ADH7 and cancer: The available peritumoral tissues analysis of ADH7 expression showed that carcinoma patients with the haplotype “CGTCGTCCC” (n = four: two heavy drinkers, one social drinker, and one non-drinker) had a lower, but not significant (p = 0.09), copy number of ADH7 (33.82 copies/μL) with respect to cancer patients (n = 6) with other haplotypes (78.02 copies/μL).
