OverviewHigh Quality Content by WIKIPEDIA articles! In genetics, rs1799913, also called A779C, is a gene variation-a single nucleotide polymorphism (SNP)- in the TPH1 gene. It is located in intron 7. The SNP association with schizophrenia has been examined in several studies, though as of 2007 with no definitive conclusion. One study has found that the SNP may be associated with heroin addiction. A218C (rs1800532) is another SNP in the same intron in the same gene. A single-nucleotide polymorphism (SNP, pronounced snip) is a DNA sequence variation occurring when a single nucleotide - A, T, C, or G - in the genome (or other shared sequence) differs between members of a species (or between paired chromosomes in an individual). For example, two sequenced DNA fragments from different individuals, AAGCCTA to AAGCTTA, contain a difference in a single nucleotide. In this case we say that there are two alleles: C and T. Almost all common SNPs have only two alleles. Full Product DetailsAuthor: Lambert M. Surhone , Miriam T. Timpledon , Susan F.
