LAMA2 and congenital muscular dystrophy: Nonsense was more frequent in LAMA2-CMD patients (56.9%, 66/116) than in LGMDR23 patients (21.4%, 3/14), consequently, combinations containing nonsense (frameshift + nonsense, nonsense + nonsense, nonsense + CNV, and nonsense + splicing) were mainly found in LAMA2-CMD patients.
