The mutation was not found in 6,500 asymptomatic individuals. Functional analysis in COS1 cells with constitutive knockdown of SHOC2 showed that, although wildtype SHOC2 rescued epidermal growth factor (EGF; <a href="/entry/131530">131530</a>)-induced ERK1 (<a href="/entry/601795">601795</a>)/2 (<a href="/entry/176948">176948</a>) phosphorylation to the extent of endogenous SHOC2, the M173I mutant was able to restore only approximately 10% above the basal level of activity. In addition, overexpression of the M173I mutant did not lead to changes in ERK1/2 activity or in AKT (see <a href="/entry/164730">164730</a>) phosphorylation. Immunoprecipitation studies in transfected 293FT cells showed that the M173I mutant failed to precipitate endogenous PP1c (see <a href="/entry/176875">176875</a>) effectively, and stimulation with EGF resulted in only a mild increase in RAF1 (<a href="/entry/164760">164760</a>) S338 phosphorylation, compared to a dramatic increase with wildtype SHOC2.

(2019)</a> identified heterozygosity for a de novo deletion/insertion (c.807_808delinsTT, NM_007373.3) in the SHOC2 gene, resulting in a Gln269_His270delinsHisTyr substitution at 2 highly conserved residues within the eighth leucine-rich repeat in the LRR domain. The mutation was not found in an in-house RASopathy database of more than 1,000 families, or in the 1000 Genomes Project, NSEuroNet, ExAC, or gnomAD databases. In transiently transfected Neuro2 cells, the mutant protein showed significantly enhanced ERK (see <a href="/entry/601795">601795</a>) activation. Coimmunoprecipitation assays from cell lysates showed increased MRAS (<a href="/entry/608435">608435</a>) binding as well as augmented binding to the catalytic subunit of PP1 (PP1C; see <a href="/entry/176875">176875</a>) with the mutant compared to wildtype SHOC2. The authors concluded that the Gln269_His270delinsHisTyr mutant is activating and enhances signaling through the MAPK (see <a href="/entry/176948">176948</a>) cascade. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=31059601" 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>Activation of fibroblast growth factor (FGF) receptors elicits diverse cellular responses, including growth, mitogenesis, migration, and differentiation. Selfors et al. (1998) shed light on the intracellular signaling pathways that mediate these processes by studies in Caenorhabditis elegans. In this organism, they screened for genes that suppress the activity of an activated form of the EGL-15 FGF receptor consistent with the functioning of these genes downstream of EGL-15. Two of these genes were soc1 and soc2, symbolized thus for 'suppressor of clear (Clr)' phenotype; the third was sem5. Selfors et al. (1998) showed that soc2 encodes a protein composed almost entirely of leucine-rich repeats, a domain implicated in protein-protein interactions. They identified a putative human homolog, SHOC2, which is 54% identical to soc2. They showed that SHOC2 mRNA was expressed in all tissues assayed and that the SHOC2 protein is localized to the cytoplasm. </p><p>Selfors et al. (1998) showed that within the leucine-rich repeats of both soc2 and SHOC2 are 2 YXNX motifs that are potential tyrosine-phosphorylated docking sites for the SEM5/GRB2 Src homology 2 domain. However, phosphorylation of these residues was not required for soc2 function in vivo, and SHOC2 was not observed to be tyrosine phosphorylated in response to FGF stimulation. Selfors et al. (1998) concluded that this genetic system identified a conserved gene implicated in mediating FGF receptor signaling in C. elegans. </p><p>Komatsuzaki et al. (2010) examined the relative expression of SHOC2 in various tissues, including blood leukocytes and lymphocytes. In the adult human cDNA panel, the highest expression was observed in testis, with relatively high expression in several immune tissues, including spleen, bone marrow, tonsil, and lymph nodes. The authors noted that expression of SHOC2 was 6 times higher in polymorphonuclear (PMN) leukocytes than in mononuclear cells, and suggested that SHOC2 might be important to proliferation or survival of PMNs. Among fetal tissues, brain showed the highest expression. </p>

<p>Sieburth et al. (1998) identified and characterized the sur8 gene in C. elegans, which positively regulates Ras-mediated signal transduction during vulval development. The authors found that reduction of sur8 function suppresses an activated Ras mutation and dramatically enhances phenotypes of mpk1/sur1 MAP kinase (see 176948) and ksr1 (601132) mutations, whereas increase of sur8 dosage enhances an activated Ras mutation. Sur8 appears to act downstream of or in parallel to Ras but upstream of Raf. Sur8 encodes a conserved protein that is composed predominantly of leucine-rich repeats. The sur8 protein interacts directly with Ras but not with the Ras(P34G) mutant protein, suggesting that sur8 may mediate its effects through Ras binding. By use of EST primers and 5-prime RACE, Sieburth et al. (1998) cloned a structural and functional SUR8 homolog in humans that specifically binds K-Ras (190070) and N-Ras (164790) but not H-Ras (190020) in vitro. </p><p>MRAS (608435), SHOC2, and protein phosphatase-1 (PP1; see 176875) interact to form a heterotrimeric holoenzyme that dephosphorylates the S259 inhibitory site on RAF kinases, activating downstream signaling. Young et al. (2018) showed that MRAS and SHOC2 function as PP1 regulatory subunits, providing the complex with striking specificity against RAF. MRAS also functions as a targeting subunit, as membrane localization is required for efficient RAF dephosphorylation and ERK (see 601795) pathway regulation in cells. </p><p>Using immunoprecipitation of endogenous LZTR1 (600574) followed by Western blotting, Umeki et al. (2019) showed that LZTR1 bound to the RAF1 (164760)-SHOC2-PPP1CB (600590) complex. Mutations in all these genes cause Noonan syndrome or Noonan-like phenotypes. Cells transfected with siRNA against LZTR1 exhibited decreased levels of RAF1 phosphorylated at ser259. </p>

<p>Using a systems biology approach based on in silico protein network analysis that identified SHOC2 as a candidate gene, Cordeddu et al. (2009) sequenced SHOC2 coding exons in a Noonan syndrome (see 163950) cohort that included 96 individuals who were negative for mutations in known disease genes. The authors identified a heterozygous mutation (S2G; 602775.0001) in the SHOC2 gene in 4 unrelated individuals. They then analyzed the SHOC2 gene in a cohort of 410 mutation-negative patients with Noonan syndrome or a related phenotype and identified 21 individuals with the same S2G mutation. All of the patients with the S2G mutation had a relatively consistent Noonan syndrome-like disorder with loose anagen hair (NSLH; 607721). Functional studies of S2G-mutant SHOC2 demonstrated introduction of an N-myristoylation site, resulting in aberrant localization and signaling. </p><p>In a male infant with typical dysmorphic facial features and other signs of Noonan syndrome, who died of congestive heart failure at 4 months of age, Hoban et al. (2012) identified heterozygosity for the S2G mutation in SHOC2. </p><p>The MRAS (608435) GTPase, a close relative of RAS oncoproteins, interacts with SHOC2 and protein phosphatase-1 (PP1; see 176875) to form a heterotrimeric holoenzyme that dephosphorylates an inhibitory site on RAF kinases, activating downstream signaling. Young et al. (2018) showed that mutations in MRAS, SHOC2, and PPP1CB (600590) that result in Noonan syndrome invariably promote complex formation with each other, but not necessarily with other interactors. Thus, Noonan syndrome in individuals with SHOC2, MRAS, or PPPC1B mutations is likely driven at the biochemical level by enhanced ternary complex formation and highlights the crucial role of this phosphatase holoenzyme in RAF S259 dephosphorylation, ERK pathway dynamics, and normal human development. </p><p>In a cohort of 92 patients with Noonan syndrome and related disorders, who were negative for mutation in 8 genes known to be associated with these disorders, Komatsuzaki et al. (2010) sequenced all coding regions of the SHOC2 gene and identified the S2G mutation in 8 patients. The mutation was shown to have arisen de novo in the 3 families for which parental DNA was available. </p><p>In a father and daughter with features overlapping those of NSLH1, Hannig et al. (2014) analyzed a RASopathy gene panel and identified heterozygosity for a missense mutation in the SHOC2 gene (M173I; 602775.0002). Functional analysis appeared to show loss of function in the ERK1/2 pathway, in contrast to the recurrent S2G variant. However, Young et al. (2018) demonstrated gain-of-function effects with the M173I mutant, which showed enhanced interaction with MRAS and PP1 and rescued ERK activation in SHOC2-deficient cells. </p><p>In an infant boy with NSLH1, Motta et al. (2019) identified heterozygosity for a de novo deletion/insertion in the SHOC2 gene (602775.0003). The mutation was not found in an in-house RASopathy database of more than 1,000 families or in public variant databases. Functional analysis demonstrated that the mutant protein, like the 2 previously reported NSLH1-associated mutants, upregulates RAS signaling through the MAPK cascade, selectively promoting SHOC2 complex formation with MRAS and the catalytic subunit of PP1 (PP1C; see 176875). </p>

<p>Jang et al. (2019) found that knockdown of shoc2 at early stages of zebrafish embryonic development affected the number of erythropoietic and myelopoietic cells and resulted in hematopoietic defects. The authors generated shoc2-knockout zebrafish and found that loss of shoc2 resulted in multiple deficiencies during embryogenesis, including gross defects in blood cell differentiation and abnormal craniofacial development. Shoc2 -/- zebrafish displayed systemic defects in neural crest specification and hematopoiesis, indicating a central role for shoc2 in embryogenesis. In addition, shoc2 -/- zebrafish displayed an array of developmental defects, emphasizing the essential role of shoc2 in coordinating activities of linear components of the erk1/erk2 pathway. Overall, shoc2 -/- zebrafish exhibited many of the clinical hallmarks associated with human NSLH1. </p>

<p>In 25 patients with a Noonan syndrome-like disorder with loose anagen hair (NSLH1; 607721), Cordeddu et al. (2009) identified heterozygosity for a 4A-G transition in exon 2 of the SHOC2 gene, resulting in a ser2-to-gly (S2G) substitution. The mutation was shown to be de novo in the 15 patients for whom parental DNA was available. Functional studies demonstrated that the S2G mutation introduces an N-myristoylation site, resulting in aberrant targeting of SHOC2 to the plasma membrane and impaired translocation to the nucleus upon growth factor stimulation. In vitro expression of mutant SHOC2 enhanced MAPK (see 176948) activation in a cell type-specific fashion. Induction of mutant SHOC2 in C. elegans engendered protruding vulva, a neomorphic phenotype previously associated with aberrant signaling. </p><p>In a male infant with typical dysmorphic facial features and other signs of Noonan syndrome, who died of congestive heart failure at 4 months of age, Hoban et al. (2012) identified heterozygosity for a de novo S2G mutation in SHOC2. The authors noted that the 'loose anagen hair' phenotype and skin features previously reported in patients with the S2G mutation were not present in this young infant, and stated that the cardiac anomaly expanded the clinical phenotype associated with the SHOC2 mutation. </p><p>In 5 unrelated children with Noonan syndrome-like disorder and loose anagen hair, Gripp et al. (2013) identified heterozygosity for the S2G mutation in the SHOC2 gene. The mutation was shown to have occurred de novo in 2 of the patients. </p><p>In 8 unrelated patients with Noonan syndrome-like disorder and loose anagen hair, Komatsuzaki et al. (2010) identified heterozygosity for the S2G mutation, which was shown to have arisen de novo in the 3 patients for whom parental DNA was available. The authors noted that short stature, relative macrocephaly, hypertelorism, low-set ears, sparse/easily pluckable hair, and a variety of skin abnormalities, including dark skin and atopic dermatitis, were commonly seen in patients positive for the S2G mutation. Young et al. (2018) studied the SHOC2 S2G mutation in HEK293T cells and observed increased ability of the mutant protein to interact with MRAS (608435) and PP1 (601790) compared to wildtype SHOC2. In cotransfection assays, the S2G mutant also efficiently dephosphorylated positions S365 in BRAF (164757) and S259 in CRAF (164760). In addition, when reexpressed in SHOC2-knockout DLD1 cells, the S2G mutant decreased the higher basal levels of S365-BRAF and S259-CRAF phosphorylation as well as the impaired epidermal growth factor (EGF; 131530)-induced ERK (see 601795) pathway activation caused by SHOC2 ablation. Serum-starved DLD1 cells reexpressing SHOC2 S2G had modestly lower phosphorylated S365-BRAF and S259-CRAF levels and modestly higher phosphorylated MEK (see 176872) and RSK (see 601684) levels compared to cells expressing wildtype SHOC2, which the authors noted was consistent with RASopathy gain-of-function mutations being only weakly activating and ERK pathway activation by such mutants being difficult to detect in many experimental systems. Young et al. (2018) concluded that the recurrent S2G variant is a gain-of-function mutant that upregulates the ERK pathway during development by selectively promoting phosphatase complex formation with MRAS and PP1. </p>

<p>In a father and daughter with features overlapping those of Noonan syndrome, with sparse and slow-growing hair (NSLH1; 607721), Hannig et al. (2014) identified heterozygosity for a c.519G-A transition (c.519G-A, NM_007373.3) in the SHOC2 gene, resulting in a met173-to-ile (M173I) substitution at a highly conserved residue within the fourth leucine-rich repeat in the LRR domain. The mutation was not found in 6,500 asymptomatic individuals. Functional analysis in COS1 cells with constitutive knockdown of SHOC2 showed that, although wildtype SHOC2 rescued epidermal growth factor (EGF; 131530)-induced ERK1 (601795)/2 (176948) phosphorylation to the extent of endogenous SHOC2, the M173I mutant was able to restore only approximately 10% above the basal level of activity. In addition, overexpression of the M173I mutant did not lead to changes in ERK1/2 activity or in AKT (see 164730) phosphorylation. Immunoprecipitation studies in transfected 293FT cells showed that the M173I mutant failed to precipitate endogenous PP1c (see 176875) effectively, and stimulation with EGF resulted in only a mild increase in RAF1 (164760) S338 phosphorylation, compared to a dramatic increase with wildtype SHOC2.

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.
