Shprintzen-Goldberg syndrome
|
Not to be confused with Goldberg-Shprintzen syndrome, which is a microcephaly often associated with Hirschsprung's disease !
Incidence: < 1/106. Autosomal dominant transmission but sporadic occurrence in 25 % of cases of mutations of the SKI gene (1p36).
Association of:
- marfanoid phenotype: arachnodactyly, aortic dilatation, thoracic deformities (pectus excavatum or carinatum), scoliosis, joint hyperlaxity
- craniosynostosis: dolichocephaly
- facial dysmorphism: maxillary hypoplasia with retrognathia, high-arched palate, bulging forehead, hypertelorism, downslanting palpebral fissures, low set ears
- cardiac anomalies: ASD, VSD, mitral valve prolapse with or without regurgitation, progressive dilatation of the aorta (80 %)
- parietal hernias
- abnormalities of the C1 and C2 vertebrae; sometimes hydrocephalus and Arnold-Chiari malformation (see this term)
- mild mental retardation is often present
Anesthetic implications:
see Marfan's syndrome ; risk of difficult intubation; fragile dura mater.
