<p>Growth factor-induced protein phosphorylation plays a key role in the signal transduction that leads to mitogenic responses.

For pharmacologic blockade, the authors engineered a bispecific receptor decoy termed 'CD4-TGFB-Trap' (4T-Trap) by attaching the TGFB-neutralizing extracellular domain of human TGFBR2 to ibalizumab, a nonimmunosuppressive human CD4 antibody. Compared with a nontargeted TGFB-Trap, 4T-Trap selectively inhibited T-helper cell Tgfb signaling in tumor-draining lymph nodes of transgenic mice expressing human CD4, causing reorganization of tumor vasculature and cancer cell death, a process dependent on Il4. The 4T-Trap-induced tumor tissue hypoxia led to increased Vegfa expression.

As multiple collagens normally expressed in the aorta are derived from early-induced target genes of TGF-beta (including COL1A1 and COL3A1), these data were considered consistent with increased (rather than decreased) TGF-beta signaling. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=15731757" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p><p><a href="#6" class="mim-tip-reference" title="Disabella, E., Grasso, M., Marziliano, N., Ansaldi, S., Lucchelli, C., Porcu, E., Tagliani, M., Pilotto, A., Diegoli, M., Lanzarini, L., Malattia, C., Pelliccia, A., Ficcadenti, A., Gabrielli, O., Arbustini, E. &lt;strong&gt;Two novel and one known mutation of the TGFBR2 gene in Marfan syndrome not associated with FBN1 gene defects.&lt;/strong&gt; Europ.

The other allele was wildtype in the constitutional DNA and showed deletion in tumor tissue.

Dissection had occurred throughout the aorta, and in 1 case in the absence of aortic root dilatation. Subarachnoid hemorrhage due to a ruptured berry aneurysm had occurred in 2 individuals. Four gene carriers and 1 deceased family member who were investigated had tortuous cerebral blood vessels. One had tortuous vertebral arteries, 2 had tortuous carotid arteries, and 1 had tortuous abdominal aorta. Two individuals were found to have a brachiocephalic artery aneurysm and a subclavian artery aneurysm, respectively. Despite the predisposition to aortic dilatation and dissection, members of the family did not frequently manifest the skeletal features of Marfan syndrome, with the exception of joint hypermobility. None had ocular lens dislocation. Striae and hernias were common.

(2017)</a> reported a 3-generation pedigree with LDS2 segregating the R497X mutation. The proband was a 48-year-old man who had been referred for genetic testing because his maternal cousin had undergone surgery for a dilated aortic root and was found to carry the R497X mutation, prompting cascade testing. The proband had a right inguinal hernia repair at age 14 years, resection of Meckel diverticulum at age 16, and gastric adenocarcinoma at 42 years of age, treated with subtotal gastrectomy and chemotherapy. A dilated aortic root of 43 mm was present at the sinus of Valsalva. His oldest son had hypertelorism, downslanting palpebral fissures, and bifid uvula. Echocardiogram showed a dilated aortic root of 40 mm. The second affected son was diagnosed antenatally with hypoplastic left heart syndrome (HLHS) on ultrasound scan at 20 weeks' gestation. At 12 years of age he had subtle nasal speech but no other features to suggest LDS. At 14 years of age he had developed downslanting palpebral fissures, hypertelorism, and arachnodactyly; these were not appreciated before. The neoascending aorta was found to be 50 mm at that time. The last affected child was 8 months old and had been diagnosed with Loeys-Dietz syndrome, with aortic root measurement at the upper limit of normal. The proband and his 2 older affected sons were being treated with irbesartan. The proband's mother and maternal aunt, ages 73 and 68 years, respectively, were both mutation carriers and were asymptomatic at the time of the proband's diagnosis. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=28225382" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<p>By screening a human hepatoma cell cDNA library with a porcine TGFBR2 cDNA as probe, Lin et al. (1992) isolated a TGFBR2 cDNA encoding a deduced 567-amino acid protein.

<strong>Gene Function</strong>

</div>
<span class="mim-text-font">
<p>Growth factor-induced protein phosphorylation plays a key role in the signal transduction that leads to mitogenic responses. Most growth factor receptors are transmembrane tyrosine kinases or are associated with cytoplasmic tyrosine kinases. However, another class of transmembrane receptors is predicted to function as serine-threonine kinases. The type II activin receptor (102581) and the types I (190181) and II TGF-beta receptors (Lin et al., 1992) belong to the serine-threonine kinase family. The many activities of TGF-beta (TGFB1; 190180) in regulating cell proliferation and differentiation and extracellular matrix production are mediated through these receptors. With the use of cells overexpressing truncated type II receptors as dominant-negative mutants to block type II receptor signaling selectively, Chen et al. (1993) demonstrated the existence of 2 receptor pathways. The type II receptors, possibly in conjunction with type I receptors, mediate the induction of growth inhibition and hypophosphorylation of the retinoblastoma gene product. The type I receptors are responsible for effects on extracellular matrix, such as the induction of fibronectin and plasminogen activator inhibitor I, and for increased JUNB (165161) expression. Selective inactivation of the type II receptors alters the response to TGF-beta in a manner similar to the functional inactivation of the RB protein (614041), suggesting a role for RB in the type II, but not the type I, receptor pathway. </p><p>Expression of the TGFBR2 gene, a putative tumor suppressor gene, is regulated by ETS transcription factors, of which FLI1 (193067) is one. Hahm et al. (1999) performed experiments to test the hypothesis that TGFBR2 may be a target of the EWS-FLI1 fusion protein found in Ewing sarcoma and related peripheral primitive neuroectodermal tumors (see 612219). Their experiments led them to conclude that indeed TGFBR2 is a direct target of EWS-FLI1. </p><p>Ozdamar et al. (2005) demonstrated that PAR6 (607484), a regulator of epithelial cell polarity and tight-junction assembly, interacts with TGF-beta receptors and is a substrate of TGFBR2. Phosphorylation of PAR6 is required for TGF-beta-dependent epithelial-mesenchymal transition in mammary gland epithelial cells and controls the interaction of PAR6 with the E3 ubiquitin ligase Smurf1 (605568). Smurf1, in turn, targets the guanosine triphosphatase RhoA (165390) for degradation, leading to a loss of tight junctions. Ozdamar et al. (2005) concluded that an extracellular cue signals to the polarity machinery to control epithelial cell morphology. </p><p>Tesseur et al. (2006) found significantly decreased levels of TGFBR2 in human brain extracts from patients with Alzheimer disease (AD; 104300) brain compared to controls; the decrease was correlated with pathologic hallmarks of the disease. Similar decreases were not seen in brain extracts from patients with other forms of dementia. In a mouse model of AD, reduced neuronal TGFBR2 signaling resulted in accelerated age-dependent neurodegeneration and promoted beta-amyloid accumulation and dendritic loss. Reduced TGFBR2 signaling in neuroblastoma cell cultures resulted in increased levels of secreted beta-amyloid and soluble APP (104760). The findings suggested a role for TGFB1 signaling in the pathogenesis of AD. </p><p>Using mice, Liu et al. (2020) showed that depletion of Tgfbr2 in Cd4 (186940)-positive T cells, but not Cd8 (see 186910)-positive T cells, halted cancer progression due to tissue healing and remodeling of blood vasculature, leading to cancer cell hypoxia and death in distant avascular regions. The host-directed protective response depended on the T-helper-2 cytokine interleukin-4 (IL4; 147780), but not on the T-helper-1 cytokine Ifng (147570). Liu et al. (2020) concluded that type-2 immunity can be mobilized as an effective tissue-level defense mechanism against cancer. </p><p>In a follow-up to the work of Liu et al. (2020), Li et al. (2020) showed that blocking TGFB signaling in CD4-positive T cells remodeled the tumor microenvironment and restrained cancer progression. In a mouse model of breast cancer resistant to immune-checkpoint or anti-Vegf (see VEGFA, 192240) therapies, inducible genetic deletion of Tgfbr2 in Cd4-positive T cells suppressed tumor growth. For pharmacologic blockade, the authors engineered a bispecific receptor decoy termed 'CD4-TGFB-Trap' (4T-Trap) by attaching the TGFB-neutralizing extracellular domain of human TGFBR2 to ibalizumab, a nonimmunosuppressive human CD4 antibody. Compared with a nontargeted TGFB-Trap, 4T-Trap selectively inhibited T-helper cell Tgfb signaling in tumor-draining lymph nodes of transgenic mice expressing human CD4, causing reorganization of tumor vasculature and cancer cell death, a process dependent on Il4. The 4T-Trap-induced tumor tissue hypoxia led to increased Vegfa expression. Vegf inhibition enhanced starvation-triggered cancer cell death and amplified the antitumor effect of 4T-Trap. Li et al. (2020) concluded that targeted TGFB signaling blockade in helper T cells elicits an effective tissue-level cancer defense response that can provide a basis for therapies directed towards the cancer environment. </p>

<p><strong><em>Role in Carcinogenesis</em></strong></p><p>
Germline (190182.0002) and somatic (e.g., 190182.0001) mutations in the TGFBR2 gene can result in hereditary nonpolyposis colorectal cancer-6 (HNPCC6; 614331).</p><p>Markowitz et al. (1995) stated that transforming growth factor-beta (TGFB; 190180) inhibits the growth of multiple epithelial cell types, and loss of this negative regulation is thought to contribute to tumor development. The TGFB growth inhibitory signal is transduced through 2 receptors, type I (TGFBR1) and type II (TGFBR2), which function as a heteromeric complex. Markowitz et al. (1995) investigated whether inactivation of TGF-beta receptors is a mechanism by which human colon cancer cells lose responsiveness to TGF-beta. They found that the TGFBR2 gene was inactivated in a subset of colon cancer cell lines (referred to as RER(+), for 'replication errors') exhibiting microsatellite instability, but not in RER(-) cells. Eight such examples, due to 3 different mutations, were identified. The mutations (e.g., 190182.0001) were clustered within small repeated sequences in the TGFBR2 gene and were accompanied by the absence of cell surface receptors. Markowitz et al. (1995) stated that TGFBR2 mutation, by inducing the escape of cells from TGF-beta-mediated growth control, links DNA repair defects (120435) with a specific pathway of tumor progression. The small repeat sequences in the TGFBR2 gene make it a favorable target for RER(+)-associated mutator mechanisms. Once generated, the proliferative advantage of cells with inactivated type II receptor would drive colon tumor progression. This pathway may also be operative in other human malignancies in which the RER(+) phenotype has been detected (reviewed by Eshleman and Markowitz, 1995). </p><p>Whereas TGFB inhibits the growth of many epithelial cell types including nontransformed colon epithelial cells, colon and many other cancer cell lines are resistant to suppression of growth by TGFB. Parsons et al. (1995) confirmed the presence of TGFBR2 mutations in 100 of 111 cases of RER+ colon cancers. As in the report of Markowitz et al. (1995), in each of these cases, a frameshift mutation was detected within a small adenine mononucleotide repeat at nucleotides 709-718 of the TGFBR2 cDNA. Insertions or deletions of adenines within this repeat produce -1, -2, or +1 frameshift mutations, resulting in predicted synthesis of truncated receptor proteins of 161, 129, or 130 amino acids, respectively. Myeroff et al. (1995) demonstrated that TGFBR2 gene mutations are also commonly present in RER+ gastric cancers. In contrast, they found that mutations in this gene are distinctly uncommon in RER+ endometrial cancers. </p><p>Souza et al. (1996) analyzed microsatellite instability within the coding regions of the TGFBR2 and IGF2R (147280) genes. They noted an anticorrespondence of IGF2R and TGFBR2 mutations. Of 31 gastrointestinal lesions studied with IGF2R or TGFBR2 mutations, 90% (28) contained mutations in one or the other, but not both, of these genes. They suggested that IGF2R and TGFBR2 genes comprise serial points in the same tumorigenesis pathway. </p><p>Tannergard et al. (1997) studied colorectal tumorigenesis in patients with HNPCC. Tumors from members of 29 HNPCC families known to have germline mutations of the MLH1 gene (120436) were studied. By using intragenic markers, inactivation of the wildtype allele of MLH1 was shown to have occurred through loss of heterozygosity and not through a somatic point mutation. Microsatellite instability was very common and occurred early in almost all colorectal tumors from HNPCC patients. Mutations in the TGFBR2 gene occurred at a high frequency in these tumors. Of colorectal cancers from HNPCC families, 63% had frameshift mutations in TGFBR2, compared with 10% of sporadic colorectal cancers. Mutations in APC (611731) and KRAS2 (190070) appeared to be as frequent in the HNPCC tumors as in the sporadic counterpart. </p><p>Lu et al. (1998) identified a germline mutation in TGFBR2 in an 80-year old patient with colorectal cancer (HNPCC6; 614331). The patient and her 2 brothers had had colorectal cancers complying with the clinical criteria of HNPCC, except that the onset of cancer was beyond 50 years of age in all cases. Constitutional DNA was heterozygous for a thr315-to-met (T315M; 190182.0002) mutation, whereas loss of the wildtype allele was observed in tumor DNA. The same mutation was present in 2 of the patient's 6 children, but they had not developed cancer. </p><p>Adjuvant chemotherapy improves survival among certain patients with stage III colon cancer. Watanabe et al. (2001) studied molecular predictors of outcome and found that retention of 18q alleles in microsatellite-stable cancers and mutation of the TGFBR2 gene in cancers with high levels of microsatellite instability pointed to a favorable outcome after adjuvant chemotherapy with fluorouracil-based regimens. </p><p><strong><em>Loeys-Dietz Syndrome</em></strong></p><p>
Identification of a 3p24.1 chromosomal breakpoint disrupting the TGFBR2 gene in a Japanese individual with a diagnosis of Marfan syndrome (154700) led Mizuguchi et al. (2004) to consider TGFBR2 as a gene underlying a phenotype referred to as Marfan syndrome type 2 (see LDS2, 610168) which mapped to a locus on chromosome 3p. They identified the mutation 1524G-A in TGFBR2 (causing the synonymous amino acid substitution Q508Q and resulting in abnormal splicing; 190182.0004) to segregate with the phenotype in the French family described by Boileau et al. (1993). In 4 unrelated probands, they identified 3 other missense mutations in TGFBR2 that led to loss of function of TGF-beta signaling activity on extracellular matrix formation. These results showed that heterozygous mutations in TGFBR2, a putative tumor suppressor gene implicated in several malignancies, are also associated with inherited connective tissue disorders. Fbn1 (134797)-deficient mice have excessive TGF-beta activity that probably underlies their tendency to develop emphysema and could explain other manifestations of Marfan syndrome (Neptune et al., 2003). Domain-specific germline mutations of TGFB1 (190180) have been described in Camurati-Engelmann syndrome (131300) and affected individuals usually have Marfanoid habitus, i.e., long slender limbs and vertebral deformation. The findings of TGFBR2 mutations provides further evidence that perturbation of TGF-beta signaling contributes to the pathogenesis of extracellular matrix disorders. </p><p>Among the 10 French probands with a diagnosis of Marfan syndrome examined by Mizuguchi et al. (2004), only 4 had mutations in TGFBR2. These 4 individuals shared a common clinical description: prominent aortic, skeletal, and skin/integument anomalies; mild ocular anomalies (except for one individual in the original family who had ectopia lentis); infrequent dural ectasia; and pulmonary abnormalities. </p><p>In 10 families with a disorder characterized by widespread perturbations in cardiovascular, craniofacial, neurocognitive, and skeletal development (see LDS1, 609192), Loeys et al. (2005) reported heterozygous mutations in the genes encoding either TGFBR1 (190181) or TGFBR2. Loeys et al. (2005) considered TGFBR2 as a candidate gene because TGF-beta signaling has a prominent role in vascular and craniofacial development in mouse models (Sanford et al., 1997; Azhar et al., 2003) and because conditional knockout of TGFBR2 in neural crest cells causes cleft palate and defects of the calvaria (Ito et al., 2003). Loeys et al. (2005) sequenced all exons of TGFBR2 and identified heterozygous mutations in 6 of 10 families (LDS2; 610168). The other 4 families were found to have mutations in the TGFBR1 gene (190181). Despite evidence that receptors derived from selected mutated alleles cannot support TGF-beta signal propagation (Mizuguchi et al., 2004), cells derived from individuals heterozygous with respect to these mutations did not show altered kinetics of the acute phase response to administered ligand. Furthermore, tissues derived from affected individuals showed increased expression of both collagen (see 120150) and connective tissue growth factor (CTGF; 121009), as well as nuclear enrichment of phosphorylated SMAD2 (601366), indicative of increased TGF-beta signaling. The data were interpreted as indicating that perturbation of TGF-beta signaling is involved in many common human phenotypes, including craniosynostosis, cleft palate, arterial aneurysms, congenital heart disease, and mental retardation. </p><p>Loeys et al. (2005) reported that histologic analysis in patients with mutations in TGFBR2 showed loss of elastin (130160) content and disarrayed elastic fibers in the aortic media similar to that in patients with classic Marfan syndrome. Structural analysis showed loss of intimate spatial association between elastin deposits and vascular smooth muscle cells. These characteristics were observed in young children and in the absence of inflammation, suggestive of a severe defect in elastogenesis rather than secondary elastic fiber destruction. In addition, they had previously observed a marked excess of aortic wall collagen in individuals with Marfan syndrome compared with age-matched controls; this collagen excess was accentuated in individuals with mutations in TGFBR2. As multiple collagens normally expressed in the aorta are derived from early-induced target genes of TGF-beta (including COL1A1 and COL3A1), these data were considered consistent with increased (rather than decreased) TGF-beta signaling. </p><p>Disabella et al. (2006) identified 3 different mutations in the TGFBR2 gene (e.g., 190182.0015) in 3 unrelated patients with a phenotype that they identified as Marfan syndrome. None of the patients had major ocular signs. </p><p>In a Japanese boy with clinical findings reported as Shprintzen-Goldberg syndrome (SGS; 182212) but consistent with Loeys-Dietz syndrome, Kosaki et al. (2006) identified heterozygosity for a splice site mutation in the TGFBR2 gene (190182.0016). Because the patient had a bifid uvula and sigmoid configuration of the brachycephalic, left common carotid, and left subclavian arteries, Robinson et al. (2006) suggested that the diagnosis of Loeys-Dietz syndrome would also be appropriate for this patient. </p><p>Singh et al. (2006) searched for TGFBR1 and TGFBR2 mutations in 41 unrelated patients fulfilling the diagnostic criteria for Marfan syndrome of the Ghent nosology (De Paepe et al., 1996) or with the tentative diagnosis of Marfan syndrome, in whom mutations in the FBN1 coding region were not identified. In TGFBR1, 2 mutations and 2 polymorphisms were detected. In TGFBR2, 5 mutations and 6 polymorphisms were identified. Reexamination of patients with a TGFBR1 or TGFBR2 mutation revealed extensive clinical overlap between patients diagnosed with Marfan syndrome type 1 (MFS1; 154700), Marfan syndrome type 2, and Loeys-Dietz syndrome. </p><p>In 2 male patients with Loeys-Dietz syndrome who had a significant history of low bone mineral density and multiple low-impact fractures, Kirmani et al. (2010) identified 2 different heterozygous mutations in the TGFBR2 gene, respectively (see, e.g., 190182.0005). </p><p><strong><em>Susceptibility To Abdominal Aortic Aneurysm</em></strong></p><p>
For a discussion of a possible association between variation in the TGFBR2 gene and susceptibility to abdominal aortic aneurysm, see AAA (100070).</p><p><strong><em>Role in Left-Right Patterning</em></strong></p><p>
By high-resolution genotyping of 262 heterotaxy (see HTX1, 306955) subjects and 991 controls, Fakhro et al. (2011) identified a 2-fold excess of subjects with rare genic copy number variations (CNVs) in heterotaxy (14.5% vs 7.4%, p = 1.5 x 10(-4)). Although 7 of 45 heterotaxy CNVs were large chromosomal abnormalities, 38 smaller CNVs altered a total of 61 genes, 22 of which had Xenopus orthologs. In situ hybridization identified 7 of these 22 genes with expression in the ciliated left-right organizer, a marked enrichment compared with 40 of 845 previously studied genes (7-fold enrichment, p less than 10(-6)). Morpholino knockdown in Xenopus of heterotaxy candidate genes demonstrated that 5 genes (NEK2, 604043; ROCK2, 604002; TGFBR2; GALNT11, 615130; and NUP188, 615587) strongly disrupted both morphologic left-right development and expression of PITX2 (601542), a molecular marker of left-right patterning. These effects were specific, because 0 of 13 control genes from rare heterotaxy or control CNVs produced significant left-right abnormalities (p = 0.001). </p>

<p>Han et al. (2005) found that human skin cancers frequently overexpress TGFB1 (190180) but exhibit decreased expression of TGFBR2. In transgenic mouse models in which Tgfb1 expression could be induced at specific stages of skin carcinogenesis in tumor epithelia expressing a dominant-negative Tgfbr2, they observed that late-stage Tgfb1 overexpression in chemically induced skin papillomas did not exert a tumor-suppressive effect and that dominant-negative Tgfbr2 expression selectively blocked Tgfb1-mediated epithelial-to-mesenchymal transition but cooperated with Tgfb1 for tumor invasion. Han et al. (2005) concluded that TGFB1 induces epithelial-to-mesenchymal transition and invasion via distinct mechanisms: TGFB1-mediated epithelial-to-mesenchymal transition requires functional TGFBR2, whereas TGFB1-mediated tumor invasion cooperates with reduced TGFBR2 signaling in tumor epithelia. </p><p>Li et al. (2006) found that mice lacking Tgfbr2 specifically in T cells had lethal inflammation associated with T-cell activation and differentiation. Maturation of Cd8-positive T cells and development of natural killer T cells were inhibited in thymus. Peripheral Foxp3 (300292)-positive regulatory T cell numbers were reduced, and Cd4-positive T-cell survival depended on Tgfb signaling. Li et al. (2006) concluded that TGFB has pleiotropic functions in T cells in terms of T-cell development, tolerance, and homeostasis. </p>

Four gene carriers and 1 deceased family member who were investigated had tortuous cerebral blood vessels. One had tortuous vertebral arteries, 2 had tortuous carotid arteries, and 1 had tortuous abdominal aorta. Two individuals were found to have a brachiocephalic artery aneurysm and a subclavian artery aneurysm, respectively. Despite the predisposition to aortic dilatation and dissection, members of the family did not frequently manifest the skeletal features of Marfan syndrome, with the exception of joint hypermobility. None had ocular lens dislocation. Striae and hernias were common. There was some overlap with Ehlers-Danlos syndrome type IV (130050), with soft translucent skin that was easily bruised. </p>

<p>In a Japanese boy with clinical findings reported as Shprintzen-Goldberg syndrome (182212) but consistent with Loeys-Dietz syndrome (LDS2; 610168), Kosaki et al. (2006) identified heterozygosity for a -2A-G transition at the splice acceptor site in intron 5 of the TGFBR2 gene. Because the patient had a bifid uvula and sigmoid configuration of the brachycephalic, left common carotid and left subclavian arteries, Robinson et al. (2006) suggested that the diagnosis of Loeys-Dietz syndrome would also be appropriate for this patient. </p>

<p>In a male patient of German origin with Loeys-Dietz syndrome (LDS2; 610168), Singh et al. (2006) identified a c.1489C-T transition in exon 6 of the TGFBR2 gene that resulted in premature termination of the protein at arg497 (R497X). Height was 195 cm, while family members were of rather short stature. Dilated ascending aorta without dissection was replaced at a size of 8.0 cm. Involvement of the skeletal system included pectus excavatum, scoliosis, and arachnodactyly with positive thumb and wrist signs. Ocular symptoms were absent. The patient was lost to follow-up. </p><p>Tooley et al. (2017) reported a 3-generation pedigree with LDS2 segregating the R497X mutation. The proband was a 48-year-old man who had been referred for genetic testing because his maternal cousin had undergone surgery for a dilated aortic root and was found to carry the R497X mutation, prompting cascade testing. The proband had a right inguinal hernia repair at age 14 years, resection of Meckel diverticulum at age 16, and gastric adenocarcinoma at 42 years of age, treated with subtotal gastrectomy and chemotherapy. A dilated aortic root of 43 mm was present at the sinus of Valsalva. His oldest son had hypertelorism, downslanting palpebral fissures, and bifid uvula. Echocardiogram showed a dilated aortic root of 40 mm. The second affected son was diagnosed antenatally with hypoplastic left heart syndrome (HLHS) on ultrasound scan at 20 weeks' gestation. At 12 years of age he had subtle nasal speech but no other features to suggest LDS. At 14 years of age he had developed downslanting palpebral fissures, hypertelorism, and arachnodactyly; these were not appreciated before. The neoascending aorta was found to be 50 mm at that time. The last affected child was 8 months old and had been diagnosed with Loeys-Dietz syndrome, with aortic root measurement at the upper limit of normal. The proband and his 2 older affected sons were being treated with irbesartan. The proband's mother and maternal aunt, ages 73 and 68 years, respectively, were both mutation carriers and were asymptomatic at the time of the proband's diagnosis. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
