Expanding the clinical and mutational spectrum of the Ehlers-Danlos syndrome, dermatosparaxis type

摘要

Purpose: The Ehlers-Danlos syndrome (EDS), dermatosparaxis type, is a recessively inherited connective tissue disorder caused by deficient activity of ADAMTS-2, an enzyme that cleaves the amino terminal propeptide domain of types I, II, and III procollagen. Only 10 EDS dermatosparaxis patients have been reported, all presenting a recognizable phenotype with characteristic facial gestalt, extreme skin fragility and. laxity, excessive bruising; and sometimes major complications due to visceral and vascular fragility.
