A male infant with lethal short limbed dwarfism is described. His father had spondyloepiphyseal dysplasia congenita and his mother had achondroplasia. It is believed that the infant inherited both of these disorders and that their combined effects resulted in early death owing primarily to severe pulmonary hypoplasia.

Introduction The role of WNT pathway in bone formation and maintenance has been extensively studied since the identification of mutations in key signalling WNT mediators in diseases with high or low bone-mass phenotypes. In humans, loss-of-function mutations in WISP3, encoding Wnt1-inducible signaling protein 3, cause progressive pseudorheumatoid dysplasia (PPD), an autosomal recessive form of ...

The prevalence of bone dysplasias is estimated to be one case per 1,000 inhabitants, which suggests that, at some point in the career of an orthopaedic surgeon, he will face with one of these patients. The aim of this paper is to review the general aspects of bone dysplasias and focus on those, which due to their frequency and importance, we consider most relevant (achondroplasia, multiple epip...

BACKGROUND A new type of corneal opacity with prominent corneal nerve fibers as an ocular complication of spondyloepiphyseal dysplasia tarda (SEDT). CASE A 58-year-old woman, diagnosed with SEDT at 5 years of age, underwent a complete ophthalmological examination. OBSERVATIONS The patient had no complaints and no history of eye disease. No relatives were reported to have suffered from SEDT....

Spondyloepiphyseal Dysplasia (SED) accompanying with congenital joint dislocations; is a genetic disease different subtypes that progress multiple dislocations. It occurs due to mutation in the CHST3 gene. This syndrome requires long and cascading surgeries, which presents short-bodied dwarfism, dislocations range of motion (ROM) limitations (knee, hip, elbow). In this case report, we describe ...

Spondyloepiphyseal dysplasia (SED) is an autosomal dominant skeletal dysplasia characterized by short stature, abnormal epiphyses and flattened vertebral bodies. SED is mainly caused by mutations in the gene encoding the type II procollagen α-1 chain (COL2A1). We looked for mutations in COL2A1 in three unrelated Chinese families with SED. Putative mutations were confirmed by RFLP analysis. We i...

A large family with dominantly inherited rhegmatogenous retinal detachment, premature arthropathy, and development of phalangeal epiphyseal dysplasia, resulting in brachydactyly was linked to COL2A1, the gene encoding proalpha1(II) collagen. Mutational analysis of the gene by exon sequencing identified a novel mutation in the C-propeptide region of the molecule. The glycine to aspartic acid cha...
