Therefore, we analyzed global melanoma data, alcohol consumption, and published ALDH2 information and found that the wild-type ALDH2 allele was strongly positively correlated with melanoma incidence (R = 0.70; p < 0.001), while the allelic variants had a modest to strong negative correlation (R = −0.70; p < 0.001 and R = −0.51; p = 0.01 for ALDH2*1/*2 and ALDH2*2/*2, respectively) [6]. Here, ALDH2 is linked to melanoma.
