In the group of EOMG patients, the previously demonstrated association with the HLA-A*01, -B*08, -C*07, and  -DRB1*0301 alleles was, also, confirmed in this study and further conditional analysis revealed that HLA-B*08 was the responsible allele for the strongest risk to MG susceptibility, detected for this haplotype (Table 1) [26]. This evidence concerns the gene HLA-DRB1 and myasthenia gravis.
