The laminin α2–related muscular dystrophies (LAMA2-RDs) are a subtype of congenital muscular dystrophy (CMD) caused by recessive variants in the LAMA2 gene [6q22–q23; OMIM*156225] (Helbling-Leclerc et al., 1995; Zhang et al., 1996). This evidence concerns the gene LAMA2 and congenital muscular dystrophy.
