Using Polymerase chain reactionsequence based typing (PCR-SBT) to genotype 64 children with DMD in HLA-A, -B,-C, -DRB1, and -DQB1 locus and 503 healthy controls in HLA-A, -B, -DRB1 locus, this study aimed to investigate associations of specific HLA alleles with, and their possible roles in the development and clinical phenotypic severity of DMD. Here, HLA-DRB1 is linked to Duchenne muscular dystrophy.
