Overview
rs121908235 is a genetic variant on gene CACNA1A associated with Cerebellar ataxia and Familial paroxysmal ataxia.
This variant is located on chromosome 19. The variations at position 13209438 are the genetic letters
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 rs121908235 there are 0 currently known genotypes .

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 Clinical Testing
Clinical testing classifications are designed to help doctors understand how genetic changes, known as variants, might affect a person’s health and guide medical decisions. Variants are labeled as Disease Causing (harmful), likely Disease Causing, Unknown Effect (unknown impact), Likely No Effect (likely not harmful), and No Effect (not harmful). This classification relies on a mix of family history, lab tests, and computer predictions to determine the impact of variants.
Variants can have different effects based on their location. Variants on the X chromosome often impact males more because they have only one X chromosome, while females have two. This influences the classification (effect) of the variant.

Pharmacogenetics
The genetic variant rs121908235 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 rs121908235. 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.

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.
