LAMB2 and cutis laxa: Mutations in at least three different laminin chain genes result in junctional epidermolysis bullosa, Laminin Gamma 3 (LAMC2),14Laminin Alpha 3 (LAMA3),15Laminin Beta 3 (LAMB3)16,17 and cutis laxa.18 Mutations in Laminin Beta 2 (LAMB2) result in Pierson’s Syndrome.19Laminin alpha4 (LAMA4) mutations are associated with cardiomyopathy20 and mutations in LAMA2 cause congenital muscular dystrophy type 1A (MDC1A).21
