BSCR is strongly associated with human leukocyte antigen HLA-A29, one of the 21 serologically defined variants of HLA-A gene [9], and FSHD is an autosomal dominant inherited myopathy that is associated in more than 95% of cases with a low number of 3.3-kb tandem repeat units, termed D4Z4, located on chromosome 4q35 [17]. This evidence concerns the gene HLA-A and facioscapulohumeral muscular dystrophy.
