Summary: Predicted to be involved in animal organ morphogenesis; axon guidance; and tissue development. Located in basement membrane. Is expressed in several structures, including excretory canal; pharyngeal-intestinal valve; pharynx; somatic nervous system; and spermatheca. Human ortholog(s) of this gene implicated in autosomal recessive limb-girdle muscular dystrophy; congenital merosin-deficient muscular dystrophy 1A; dilated cardiomyopathy 1JJ; muscular dystrophy; and myopia. Orthologous to several human genes including LAMA1 (laminin subunit alpha 1) and LAMA2 (laminin subunit alpha 2). [provided by Alliance of Genome Resources, Apr 2022]
