Overview

rs25487 is a genetic variant on gene XRCC1.

This variant is located on chromosome 19. The variations at position 43551574 are the genetic letters C/C, T/T, G/T, C/T

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 combination is referred to as genotype. For variant rs25487 there are 4 currently known genotypes : C/C, T/T, G/T or C/T

Did you know genetic variants affect drugs?

Mutations are changes in genes and genetic variations are differences in the DNA among people. Variants are tiny changes in just one piece of the DNA while haplotypes are groups of these changes that usually come together.

Pharmacogenetics

The genetic variant rs25487 impacts how certain medications work in the body. This difference may cause some of us to require different dosage amounts to achieve the desired effects, while others might experience more apparent side-effects. As a result, healthcare providers may need to adjust prescriptions for those individuals with rs25487. Ultimately, understanding our genetic makeup helps improve the overall effectiveness and usability of medications. Tailoring treatments based on genetics ensures a safer, more personalized healthcare experience.
