Congenital muscular dystrophies (CMD/MDC)

Definition:

Congenital muscular dystrophies (CMDs) are a heterogeneous group of inherited disorders characterized by muscle weakness from birth and variable clinical manifestations of the eye and central nervous system. According to the disease mechanisms, the CMDs may be grouped as follows: defects in genes encoding for structural proteins of the basal membrane or extracellular matrix of the skeletal muscle fibers, which include collagen 6 genes, laminin alpha2 chain and integrin alpha7; defects in genes encoding for putative or demonstrated glycosyltransferases, which include POMT1, POMT2, POMGnT1, fukutin, fukutin-related protein (FKRP), Large, and ISPD; defects in ER and nuclear proteins, which are selenoprotein 1 and lamin A/C.
