Overview
rs671 is a genetic variant on gene ALDH2 associated with Alcohol dependence.
This variant is located on chromosome 12. The variations at position 111803962 are the genetic letters A/A, G/G, A/G
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 rs671 there are 3 currently known genotypes : A/A, G/G or A/G

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.
Conditions & Traits of rs671
The different genotypes of variant rs671 can affect the likelyhood of developing certain traits or conditions. Current research shows that 1 condition and 0 traits are associated with rs671. The following table shows the relationship between genotypes and conditions and traits.
Classification of Variants
Variants can be classified either based on scientific studies or clinical tests. Scientific studies classifications aim to uncover the function of genetic variants and their role in conditions, traits, and evolution. Variants are categorized according to their functional effect, such as loss-of-function (reduced gene activity), gain-of-function (increased gene activity), neutral (no significant impact) or evolutionary conservation. This classification uses experimental data, population studies, and computational analyses to understand the long-term effects of variants. Clinical testing classifications, however, focus on the immediate health impact on the human body, distinguishing five categories from disease causing (harmful) to no effect (not harmful). This classification relies on a mix of family history, lab tests, and computer predictions, aiming to assist doctors in making medical decisions.

Pharmacogenetics
The genetic variant rs671 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 rs671. 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.
