Genetic Variation and Cancer Risk
A study found that "the ADH1C*1 allele and genotype ADH1C*1/1 were significantly more frequent in patients with alcohol-related cancers…" A European study has found two gene variants which offer "significant" protection against mouth and throat cancers. Alcohol is a known porphyrinogenic chemical. Several European studies have linked the inherited hepatic porphyrias with a predisposition to hepatocellular carcinoma. Typical risk factors for HCC need not be present with the acute hepatic porphyrias, specifically acute intermittent porphyria, variegate porphyria and hereditary coproporphyria. Porphyria cutanea tarda is also associated with HCC, but with typical risk factors including evidence of hepatotropic viruses, hemochromatosis and alcoholic cirrhosis. Tyrosinemia Type I, an inherited disorder in tyrosine metabolism impacting the second enzyme in the heme metabolic pathway is associated with a high risk of developing HCC in younger populations, including children.

Famous quotes containing the words genetic, cancer and/or risk:
“Man is not merely the sum of his masks. Behind the shifting face of personality is a hard nugget of self, a genetic gift.... The self is malleable but elastic, snapping back to its original shape like a rubber band. Mental illness is no myth, as some have claimed. It is a disturbance in our sense of possession of a stable inner self that survives its personae.”
—Camille Paglia (b. 1947)
“I’m beginning to believe that Killer Illiteracy ought to rank near heart disease and cancer as one of the leading causes of death among Americans. What you don’t know can indeed hurt you, and so those who can neither read nor write lead miserable lives, like Richard Wright’s character, Bigger Thomas, born dead with no past or future.”
—Ishmael Reed (b. 1938)
“Better risk loss of truth than chance of error—that is your faith-vetoer’s exact position. He is actively playing his stake as much as the believer is; he is backing the field against the religious hypothesis, just as the believer is backing the religious hypothesis against the field.”
—William James (1842–1910)
