Abstract

Autosomal recessive Weissenbacher-Zweymuller syndrome (WZS) is a skeletal dysplasia characterized by rhizomelic dwarfism and severe hearing loss. Mutations in the COL11A2 gene have been implicated in causing the autosomal dominant form of this syndrome as well as non-ocular Stickler syndrome and the autosomal recessive syndrome otospondylomegaepiphyseal dysplasia (OSMED). In a consanguineous Bedouin tribe living in Southern Israel, five individuals affected by autosomal recessive WZS were available for genetic analysis. Homozygosity of a mutation in the COL11A2 gene was found in all affected individuals. This finding lends molecular support to the clinical notion that autosomal recessive WZS and OSMED are a single entity.
