The mutations in the Cartilage Oligomeric Matrix Protein (COMP) gene are associated two common and allelic bony dysplasias: Psuedoachondroplasia (PSACH) and Multiple epiphyseal dysplasias-1 (MED-1). The characteristic radiological features of both has been well established in the literature, with areas of overlap between the two in certain forms of mild PSACH and severe MED. MED is also a genotypically and a phenotypically heterogeneous disease. Here, we emphasise the salient radiological features which aid in the diagnosis of PSACH and COMP MED; which may enable a targeted molecular analysis.
