OverviewHigh Quality Content by WIKIPEDIA articles! In genetics, rs5569 (A1287G or G1287A) is a genetic variant. It is a single nucleotide polymorphism (SNP) in the SLC6A2 gene in exon 9. This gene codes the norepinephrine transporter. The SNP is a silent substitution and the nucleotides of both variants code a threonine amino acid. Several research studies have examined the effect of the variant in relation to alcohol dependence, attention deficit hyperactivity disorder, diabetes, major depressive disorder, panic disorder, Tourette syndrome and personality traits. None of the studies have found an association. 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.
