4-digit alleles are preferentially reported unless a 2-digit allele is significantly more associated. P values (uncorrected), OR and 95% CI were calculated in a regression including the most significantly associated independent variants. Associations reaching study-wide significance are reported (p<2.9×10–5).
HLA, human leucocyte antigen.
