Have occurred in EDS VI (Kyphoscoliotic sort) have not been reported in BCS patients to date.DiscussionDifferential diagnosisIn maintaining having a generalised connective tissue disorder, musculoskeletal features happen to be present in manyDifferential diagnoses of BCS are summarised in Table .These have lengthy been known to consist of EhlersDanlos syndrome (EDS) type VI (OMIM:), formerly described as EDS By means of.Indeed, BCS has previously, on occasion, been termed EDS VIB, on the other hand, this nomenclature has also been made use of for a array of other phenotypes that, like BCS, show a normal LP:HP ratio, but are genetically and, ordinarily, clinically, distinct from it, such as the musculocontractural type of EDS (OMIM:).ThisBurkitt Wright et al.Orphanet Journal of

one example is the dermatosparactic form of EDS (VIIc, OMIM , due to mutations in ADAMTS ) has dramatic skin manifestations not noticed to date in BCS sufferers, while the extremely rare patients with recessive OI on account of biallelic mutations in collagen I or V genes have ordinarily had severe bone fragility and once again no dramatic eye phenotype reported.Recessive CRTAP mutations also appear to lead to extreme bone phenotypes but without having considerable ophthalmic complications , producing it most likely that these Al support and knowledge amount of care staff, and inside the

condition, but serious early onset scoliosis may very well be a lot more characteristic of EDS VI .An algorithm to help diagnosis of BCS is suggested in Figure .Other differential diagnoses for BCS include things like the musculocontractural kind of EDS, an additional autosomal recessive connective tissue disorder (OMIM:), on account of biallelic mutations in CHST .Indeed, one particular person whose sample was referred for genetic testing for BCS following corneal rupture was subsequently found to have a homozygous mutation in CHST.Fixed adducted thumbs have already been described as a
