Genetic variation
4:g.99318162T>C
Overview
4:g.99318162T>C is a genetic variant on gene ADH1B associated with Alcohol dependence and Alcohol use disorder.
This variant is located on chromosome 4. The variations at position 99318162 are the genetic letters A/A, C/C, G/G, T/T, G/T, A/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 4:g.99318162T>C there are 7 currently known genotypes : A/A, C/C, G/G, T/T, G/T, A/T or C/T

Did you know genetic variants affect drugs?
Mutations are random changes in the DNA 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.

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.

Variant Classification based on Scientific Studies
Scientific studies classifications aim to uncover how genetic variants function and their roles in diseases, traits, and evolution. Variants are categorized based on their functional impact, such as loss-of-function (reduces gene activity), gain-of-function (increases gene activity), neutral (no significant impact), or evolutionary conservation. This classification uses experimental data, population studies, and computational analyses to understand variant effects. Unlike clinical testing, which focuses on immediate health impacts, scientific studies explore broader genetic mechanisms and long-term implications.

Genotype 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.
