    Type 2 collagen disorders encompass a diverse group of skeletal dysplasias that are commonly associated with orthopedic, ocular, and hearing problems. However, the frequency of many clinical features has never been determined. We retrospectively investigated the clinical, radiological, and genotypic data in a group of 93 patients with molecularly confirmed SEDC or a related disorder. The majority of the patients (80/93) had short stature, with radiological features of SEDC (n=64), others having SEMD (n=5), Kniest dysplasia (n=7), spondyloperipheral dysplasia (n=2), or Torrance-like dysplasia (n=2). The remaining 13 patients had normal stature with mild SED, Stickler-like syndrome or multiple epiphyseal dysplasia. Over 50\% of the patients had undergone orthopedic surgery, usually for scoliosis, femoral osteotomy or hip replacement. Odontoid hypoplasia was present in 56\% (95\% CI 38-74) and a correlation between odontoid hypoplasia and short stature was observed. Atlanto-axial instability, was observed in 5 of the 18 patients (28\%, 95\% CI 10-54) in whom flexion-extension films of the cervical spine were available

    Expanding the clinical and mutational spectrum of the Ehlers-Danlos syndrome, dermatosparaxis type
    (NATURE PUBLISHING GROUP, 2016-01-01) Van Damme, Tim; Colige, Alain; Syx, Delfien; Giunta, Cecilia; Lindert, Uschi; Rohrbach, Marianne; Aryani, Omid; Alanay, Yasemin; Simsek-Kiper, Pelin Ozlem; Kroes, Hester Y.; Devriendt, Koen; Thiry, Marc; Symoens, Sofie; De Paepe, Anne; Malfait, Fransiska
    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
