Large kindred with Ehlers-Danlos syndrome type IV due to a point mutation (G571S) in the COL3A1 gene of type III procollagen: low risk of pregnancy complications and unexpected longevity in some affected relatives.

Abstract excerpt

Ehlers-Danlos syndrome (EDS) type IV is an autosomal dominant connective tissue disorder. Early morbidity and mortality results from rupture of vessels and internal organs. A large kindred with EDS type IV was studied clinically, and the biochemical defects and underlying mutation in the COL3A1 gene that encodes the chains of type III procollagen were identified. A G-->A transition results in a single amino acid...
