Interest in glypican-3 (GPC3), a member of the glypican-related integral membrane heparan sulfate proteoglycans (GRIPS) family, has increased with the finding that it is mutated in the Simpson-Golabi-Behmel overgrowth syndrome (Pilia et al. [1996] Nat. Genet. 12:241-247). The working model suggested
to Xq27. It is not known whether severe, familial cases, such as ours, are genetically distinct from and map to another locus. Final resolution of the genetic basis of the phenotypic variability in SGBS must await cloning and mutation analysis of the SGBS gene(S).
Simpson-Golabi-Behmel syndrome (SGBS) is an X-linked overgrowth syndrome caused by deletions in glypican 3 (GPC3). SGBS is characterized by pre- and postnatal overgrowth, a characteristic facial appearance, and a spectrum of congenital malformations which overlaps that of other overgrowth syndromes.
