Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In genetics, rs1800532 (A218C) is a genetic variant. It is a single nucleotide polymorphism in the TPH1 gene and located in intron 7. It has been examined in relation to personality traits. 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 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.
