rs671 is a genetic variant on gene ALDH2 associated with Chronic obstructive pulmonary disease and Coronary artery disease.

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

The different genotypes of variant rs671 can affect the expression or likelyhood of developing certain traits or conditions. Current research shows that 8 conditions and 0 traits are associated with rs671. The following table shows the relationship between genotypes and conditions and traits.

Did you know genetic variants affect drugs?

Genetic variants can influence how our body reacts to certain drugs. The presence of specific genetic variants can increase or decrease the efficiency and effectiveness of a drug, impacting how well it works inside our system. Additionally, certain genetic variants can heighten or lessen the toxicity of a drug, thereby affecting the risk of unwanted side effects. They can also alter how a drug is metabolized, which influences the appropriate dosage one should receive.

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.

rs671 is commonly tested together with other variants on the same gene.

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.
