The AA genotype might be a resistance factor against brucellosis. It was more frequent in the controls than the patients (P= 0.0035) [R].
The frequency of ''A'' allele was lower in patients with Graves' disease (GD) than controls (P = 0.011) [R].
The ''G'' allele remained significantly higher in graft versus host disease (GVHD) after allogeneic hematopoietic stem cell transplantation grade (0-I) group compared to those of grade (II-IV) group (P = 0.05) [R].
G/A variant alleles increase the risk of rheumatoid arthritis (RA) [R].
