Finally, the variant in the ATP2A1 gene associated with congenital muscular dystrophy [56] presented an LD of r2 = 0.88 with the lead SNP in both the ST GWAS for rump and the MT GWAS for muscular development traits (see Additional file 1: Fig. S10). Here, ATP2A1 is linked to congenital muscular dystrophy due to LMNA mutation.
