Impairment of peripheral nerve myelination causing various axonal abnormalities, including naked axons and axons with abnormal myelin, was reported in Largemyd/myd mice [39], Fukutin-deficient chimeric mice [40], a patient with LAMA2 deficiency [41], and a Fukuyama CMD patient [42]. Here, LAMA2 is linked to congenital muscular dystrophy.
