Weaver Syndrome; Wvs

Description

Weaver syndrome comprises pre- and postnatal overgrowth, accelerated osseous maturation, characteristic craniofacial appearance, and developmental delay. Most cases are sporadic, although autosomal dominant inheritance has been reported. Although there is phenotypic overlap between Weaver syndrome and Sotos syndrome (OMIM ), distinguishing features of Weaver syndrome include broad forehead and face, ocular hypertelorism, prominent wide philtrum, micrognathia, deep horizontal chin groove, and deep-set nails. In addition, carpal bone development is advanced over the rest of the hand in Weaver syndrome, whereas in Sotos syndrome carpal bone development is at or behind that of the rest of the hand (summary by Basel-Vanagaite, 2010).The 'Weaver-like' syndrome reported by Stoll et al. (1985) in a mother and son may be a separate entity.Sotos syndrome (OMIM ), which shows considerable phenotypic overlap with Weaver syndrome, is caused by mutation in the NSD1 gene (OMIM ) on chromosome 5q35.
