An allelic variant of the 5HT7 serotonin receptor was discovered. Family study data indicate that this variant can be correlated to alchoholic offerders. DNA encoding the variant protein, the protein itself, vectors containing the variant gene and cell lines carrying a vector with the variant gene are part of the invention.

Allelic variation of the serotonin 5HT7 receptor

A method of detecting abnormal serotonergic function in an impulsive human subject is disclosed. The method comprises detecting an L allele of a gene encoding tryptophan hydroxylase. The invention also includes an isolated nucleic acid having a sequence specific to an L allele of a gene encoding tryptophan hydroxylase. The nucleic acid may migrate in a denaturing gel at the same rate as a second nucleic acid specific to a corresponding region of a U allele of a gene encoding tryptophan hydroxylase, and migrate in a nondenaturing gel at a rate about 1.02 times the migration rate of the second nucleic acid.
