Spondyloepimetaphyseal dysplasia, aggrecan type

A new form of skeletal dysplasia with manifestations of severe short stature, facial dysmorphism and characteristic radiographic findings. To date, three cases have been described, all originating from the same family. The disease results from a missense mutation affecting the C-type lectin domain of aggrecan (AGC1 gene; chromosome 15) which regulates endochondral ossification. Transmission is autosomal recessive.
