Integrin alpha-7 functions as a laminin receptor that is essential for skeletal muscle fiber anchorage, structural integrity, and myoblast migration during muscle development. Mutations cause autosomal recessive congenital muscular dystrophy due to ITGA7 deficiency, presenting in early infancy with muscle weakness and developmental delays. This gene is highly constrained against loss-of-function mutations, indicating its critical importance for normal muscle function.
