Overall, this meta-analysis involved 3200 MS patients and 3069 matched healthy controls and it did not evidence significant association of the LILRA3 deletion [carriers of LILRA3 deletion: p = 0.25, OR (95% CI) = 1.07 (0.95–1.19)], even after stratification by gender and the HLA-DRB1*15:01 risk allele. This evidence concerns the gene HLA-DRB1 and myeloid sarcoma.
