Overview

SNPs are specific locations in the DNA where genetic variations can occur. Every person has a unique composition of variations.

SNP rs12913832 is located on chromosome 15. The most common variation at this position is the A. People with other variations might have letter G instead.

Since humans have each twice (one from each parent), these letter-variations occur on both chromosomes. People can have the same or different letters on both chromosomes. Every person's individual variation assembly is referred to as genotype. For SNP rs12913832 there are 3 currently known genotypes: G/T , G/G or T/T

Effects relating to rs12913832

Your genetic code influences you in many ways. This may be by either causing you to have a specific trait (eg. Eye colour) or your risk of developing a specific disease.

Each combination of genetic letters (called bases) is called a genotype for this specific SNP. Each Genotype can have a different effect on your body. The table below shows which genotype causes which traits or disease risks.

Current research shows 2 disease risks associated with rs12913832. The following table shows the relationship between genotype and .

The T allele of rs12913832 showed a dominant effect on darker hair color in that the heterozygote carriers had a further increased OR of black hair (genotypic OR: 8.6; 95% CI: [3.918.9]; P=7.2108; Supplementary Table S2)

Distribution

Knowing your genome can actually tell you a lot about your ancestors.

The prevalence of the different genotypes is based on the native inhabitants of a region. In the map below you see how common each genotype is in the native inhabitants of those regions. Since genetic material is passed down form generation to generation, your DNA shows traces of the geographical origins of your ancestors.

This data is based on “The 1000 Genomes Project” which established one of the most detailed overviews of human genetic variations across the globe. The regions are broadly categorized into five continental groups: Africa, America, Europe, South Asia and East Asia. All continental groups together display the global prevalence. Click through the regions, to learn more about the local prevalence of the possible genotypes.

At present, there is no distribution data available for SNP rs12913832.
