▶Genetic variants at 4q21, 4q23 and 12q24 are associated with esophageal squamous cell carcinoma risk in a Chinese populationAssociationN=4,412Yong Gao et al.(2013)· Human Genetics
A case-control study of 2,139 esophageal squamous cell carcinoma (ESCC) cases and 2,273 controls in a Chinese population examined six SNPs previously associated with upper aerodigestive tract cancers in Europeans. Four SNPs showed significant association with ESCC risk: rs1494961 at 4q21 (OR=1.15, 95% CI=1.05-1.26), rs1229984 in ADH1B at 4q23 (OR=1.24, 95% CI=1.13-1.36), rs1789924 near ADH1C at 4q23 (OR=1.20, 95% CI=1.03-1.39), and rs671 in ALDH2 at 12q24 (OR=0.83, 95% CI=0.75-0.91). Combined analysis showed significant allele-dosage effects with individuals carrying 5+ risk alleles having 1.76-fold increased ESCC risk.
About ADH1C
This gene encodes class I alcohol dehydrogenase, gamma subunit, which is a member of the alcohol dehydrogenase family. Members of this enzyme family metabolize a wide variety of substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids, and lipid peroxidation products. Class I alcohol dehydrogenase, consisting of several homo- and heterodimers of alpha, beta, and gamma subunits, exhibits high activity for ethanol oxidation to acetaldehyde, thus playing a major role in ethanol catabolism. Three genes encoding alpha, beta and gamma subunits are tandemly organized in a genomic segment as a gene cluster. An association between ADH1C polymorphism and alcohol dependence has not been established. [provided by RefSeq, Sep 2019]
