Additionally, the intramuscular injection of the AAV9 vector containing laminin subunit alpha 1 (LAMA1) gene showed the recovery of muscle function in a mouse model of congenital muscular dystrophy type 1A (MDCA1A), which is caused by the LAMA2 gene mutation [26], probably due to the compensatory effect of LAMA1 for LAMA2 defect. Here, LAMA2 is linked to Congenital muscular dystrophy type 1A.
