ALDH2 and tuberculosis: Further referent and alternative (co-dominant, dominant, and recessive model) analysis of ALDH2Glu487Lys revealed that its genetic mode for the risk of TB is apparently protective and dominant, when comparing the magnitude (OR) of associations of heterozygotes and homozygotes for ALDH2*487Lys, although no significance was detected for homozygotes due to a low number of samples (Table 2).
