摘要：
A moderately severe form of autosomal dominant (AD) spondyloepiphyseal dysplasia (SED) has been documented in 14 individuals in 3 generations of a family in Cape Town, South Africa. Affected persons had a short trunk; radiographic investigations indicated that skeletal involvement was worst in the hips and spine. Linkage studies with restriction fragment length polymorphisms (RFLPs) associated with the COL2A1 gene and the phenotype yielded a maximal LOD score of 4.51 at theta = 0.00. This result suggests that the structural locus for type II collagen is primarily involved in the pathogenesis of this form of SED.
