characteristics.</h4><p>Shprintzen-Goldberg syndrome (SGS) is characterized by: delayed motor and cognitive milestones and mild-to-moderate intellectual disability; craniosynostosis of the coronal, sagittal, or lambdoid sutures; distinctive craniofacial features; and musculoskeletal findings including olichostenomelia, arachnodactyly, camptodactyly, pectus excavatum or carinatum, scoliosis, joint hypermobility or contractures, pes planus, foot malposition, and C1-C2 spine malformation. Cardiovascular anomalies may include mitral valve prolapse, secundum atrial septal defect, and aortic root dilatation. Minimal subcutaneous fat, abdominal wall defects, and myopia are also characteristic findings.</p></div><div><h4 class="inline">Diagnosis/testing.</h4><p>The diagnosis of SGS is established in a proband with a heterozygous pathogenic variant in <i>SKI</i> identified by molecular genetic testing.</p></div><div><h4 class="inline">Management.</h4><p><i>Treatment of manifestations:</i> Early intervention for developmental delay with placement in special education programs; standard management of cleft palate and craniosynostosis; surgical fixation may be necessary for cervical spine instability; routine management for scoliosis; surgical correction for pectus excavatum is rarely indicated; physiotherapy for joint contractures; clubfoot deformity may require surgical correction. If aortic dilatation is present, treatment with beta-adrenergic blockers or other medications should be considered in order to reduce hemodynamic stress; surgical intervention for aneurysms may be indicated; treatment of myopia as per ophthalmologist; surgical repair of abdominal hernias as indicated.</p><p><i>Prevention of secondary complications:</i> Subacute bacterial endocarditis prophylaxis is recommended for dental work or other procedures for individuals with cardiac complications.</p><p><i>Surveillance:</i> Developmental assessment with each visit; cervical spine evaluation and clinical evaluation for scoliosis as recommended by orthopedist; imaging per cardiologist familiar with this condition; ophthalmology exams as recommended by ophthalmologist.</p><p><i>Agents/circumstances to avoid:</i> Contact sports; use of agents that stimulate the cardiovascular system; activities that may lead to joint pain and/or injury.</p></div><div><h4 class="inline">Genetic counseling.</h4><p>SGS, caused by a heterozygous pathogenic variant in <i>SKI</i>, is an autosomal dominant disorder. Most individuals with SGS have unaffected parents, suggesting that the causative variant has occurred either as a <i>de novo</i> event in the affected individual or as a result of germline mosaicism in one of the parents. Affected sibs born to unaffected parents support the occurrence of germline mosaicism in some families with SGS. Once a <i>SKI</i> pathogenic variant has been identified in an affected family member, prenatal testing for a pregnancy at increased risk and preimplantation genetic testing are possible.</p></div></div><div id="sgs.Diagnosis"><h2 id="_sgs_Diagnosis_">Diagnosis</h2><p>Formal diagnostic criteria for Shprintzen-Goldberg syndrome (SGS) have not been established.</p><div id="sgs.Suggestive_Findings"><h3>Suggestive Findings</h3><p>SGS <b>should be suspected</b> in individuals with a combination of the following clinical (see <a class="figpopup" href="/books/NBK1277/figure/sgs.F1/?report=objectonly" target="object" rid-figpopup="figsgsF1" rid-ob="figobsgsF1">Figure 1</a>) and radiographic features:</p><div class="iconblock whole_rhythm clearfix ten_col fig" id="figsgsF1" co-legend-rid="figlgndsgsF1"><a href="/books/NBK1277/figure/sgs.F1/?report=objectonly" target="object" title="Figure 1.
