Have occurred in EDS VI (Kyphoscoliotic form) haven't been reported in BCS individuals to date.DiscussionDifferential diagnosisIn keeping using a generalised connective tissue disorder, musculoskeletal capabilities have already been present in manyDifferential diagnoses of BCS are summarised in Table .These have long been identified to include things like EhlersDanlos syndrome (EDS) sort VI (OMIM:), formerly described as EDS By way of.Certainly, BCS has previously, on occasion, been termed EDS VIB, nevertheless, this nomenclature has also been employed for any selection of other phenotypes that, like BCS, show a typical LP:HP ratio, but are genetically and, typically, clinically, distinct from it, for example the musculocontractural form of EDS (OMIM:).ThisBurkitt Wright et

ZIP OMIM Other, rare, autosomal recessive types of Ehlers Danlos syndrome (EDS) and osteogenesis imperfecta (OI) have also been characterised, but these would be unlikely to present within the differential diagnosis of BCS, for instance the dermatosparactic type of EDS (VIIc, OMIM , on account of mutations in ADAMTS ) has dramatic skin manifestations not observed to date in BCS patients,

ophthalmic complications , making it likely that these severe recessive OI presentations will be in a position to be differentiated from BCS.predicament suggests that BCS remains greatest classified as a separate entity.Clinical differentiation amongst EDS VI and BCS could possibly be difficult, but patients with EDS VI frequently have extra pronounced generalised connective tissue manifestations.Premature death from arterial or visceral rupture, comparable to that observed in EDS sort IV (OMIM:) is nicely documented in EDS form VI , but no such complications have but been
