Abstract
We present a family with findings of Ehlers‐Danlos syndrome type VIII and a presenile appearance due to decreased subcutaneous tissue with drawn skin, defective wound healing, contractures, and thin hair. To investigate this syndrome, we studied collagen production and the growth properties of cultured fibroblasts taken from affected relatives. We could not find evidence of a collagen defect or premature senescence of cultured fibroblasts, although the fibroblasts may have a decreased growth rate. We conclude that this family has findings of EDS VIII and premature aging and propose that this overlapping phenotype is due to a single pathogenetic mechanism. Our studies of collagen production and fibroblast replication did not discern this mechanism.
