Is alcoholism a genetic disorder

Answer 1

Alcoholism is a big problem among many Americans. Although it has not been proven that Alcoholism is gene related, there is a bit of evidence. Now studies show the the F1 generation of the RHD2 gene have some alcoholism related signs but no specific evidence suggests any real link. On average 1 out of 13 Americans is affected by Alcoholism so based on the evidence we have the so called "Alcoholism gene" shows a recessivetendency. Based on majority grouping and known scientific evidence, this gene is in fact recessive.

Answer 2

There is evidence to suggest that alcohol and drug addictions may be hereditary, at least in part. Studies have shown that 75% of alcoholics or addicts have at least one blood relative who is an alcoholic or addict.

Answer 3

DNA testing is available on a clinical basis for: RLBP1 (autosomal recessive, Bothnia type RP) RP1 (autosomal dominant, RP1) RHO (autosomal dominant, RP4) RDS (autosomal dominant, RP7) PRPF8 (autosomal dominant, RP13) PRPF3 (autosomal dominant, RP18) CRB1 (autosomal recessive, RP12) ABCA4 (autosomal recessive, RP19) RPE65 (autosomal recessive, RP20) For all other genes, molecular genetic testing is available on a research basis only. RP can be inherited in an autosomal dominant, autosomal recessive, or X-linked manner. X-linked RP can be either recessive, affecting primarily only males, or dominant, affecting both males and females, although males are usually more mildly affected. Some digenic (controlled by two genes) and mitochondrial forms have also been described.

Answer 4

alzheimer's disease is recessive, and most likely it takes a homozygous pair to pass down to the next generation.

Answer 5

I think it is a complex trait based on some dominant and some recessive alleles with no simple mendelian inheritance pattern.
