As exhibited in Table 4, the analysis of HLA-DRB1 and DQB1 allele associations showed that DRB1*03:01–DQB1*02:01 was the most frequent association, observed in 10.4% of MS patients versus 3% of controls (p = 0.01, corrected p = 0.49), followed by HLA DRB1*15:01–DQB1*06:02 association, with 9% in patients and 5% in the control group with a statistically significant difference (p = 0.004, corrected p = 0.009). The gene discussed is HLA-DRB1; the disease is myeloid sarcoma.
