A rare skeletal disorder belonging to the group of spondyloepimetaphyseal dysplasia. The disease has characteristics of progressive dwarfism with short trunk, protruding sternum, microcephaly and mental retardation of varying severity. Caused by mutations of the DYM gene (18q21.1). The large majority of mutations identified in the gene predict a loss of function of its product. DYM is expressed in the majority of tissue and codes for Dymeclin, a protein that interacts with membranes of the Golgi apparatus, but its role within the cell is still unknown. Transmission is autosomal recessive.
