Spondyloepiphyseal dysplasia, Kimberley type

Disease with characteristics of short stature and premature degenerative arthropathy. It has been described in one multigenerational South African family of English white descent. The main clinical features may include proportionate short stature (less than fifth percentile for age), stocky habitus and early-onset progressive osteoarthropathy of the weight-bearing joints. Radiographic features are flattened vertebral bodies with sclerosis and prominent endplate irregularity and flattened femoral epiphyses. Caused by mutation in the aggrecan gene (AGC1, locus 15q26.1) and transmitted as an autosomal dominant trait.
