Description: (OMIM) Rock et al. (2008) provided an overview of the brachyolmias, a heterogeneous group of skeletal dysplasias that affect primarily the spine. Type 1 brachyolmia includes the Hobaek and Toledo (271630) forms and is inherited in an autosomal recessive ...
Clinical Description OMIM Brachyolmia comes from the Greek for 'short trunk.' Occasional patients have been described with short stature limited to the trunk and with radiologic changes likewise only in the spine (reviews by Fontaine et al., 1975, and Shohat et ...
