Genotype to phenotype correlations in cartilage oligomeric matrix protein associated chondrodysplasias.

ABSTRACT: Pseudoachondroplasia (PSACH) and autosomal dominant multiple epiphyseal dysplasia (MED) are chondrodysplasias resulting in short-limbed dwarfism, joint pain and stiffness and early onset osteoarthritis. All PSACH, and the largest proportion of MED, result from mutations in cartilage oligomeric matrix protein (COMP). The first mutations in COMP were identified in 1995 in patients with both PSACH and MED and subsequently there has been over 30 publications describing COMP mutations in at least 250 PSACH-MED patients. However, despite these discoveries, a methodical analysis of the relationship between COMP mutations and phenotypes has not been undertaken. In particular, there has, to date, been little correlation between the type and location of a COMP mutation and the resulting phenotype of
