SCN1A
Effect of Variations on the SCN1A
Variants are common variations in genes that can significantly impact the health and traits of an individual. This section shows all variants that are located on SCN1A, as well as their associated conditions, traits and drugs.
Did you know that gene anomalies are relatively common?
On average, each person has approximately 100 to 400 genes with variations or mutations (with different genes being affected in different individuals). However, in most cases, the matching gene on the other chromosome in the pair is normal, which helps prevent potential negative effects. In the general population, the likelihood of an individual inheriting two copies of the same abnormal gene—and thus developing a genetic disorder—is very low. However, this risk increases significantly for children of parents who are closely related by blood.

Conditions caused and influenced by SCN1A
Genetic abnormalities can affect the chance of developing a condition by raising or lowering the risk. They can change how a gene works, leading to faulty or missing proteins. However, even with a higher genetic risk, a condition may not develop because factors like environment and lifestyle also have an impact.
Variants located on SCN1A
The genetic code of a gene is virtually identical between differen people. Only a few individual letters differ from one person to the next.
Did you know genetic variations may affect drugs?
Genetic differences can affect how our body reacts to drugs. Some genes can make a drug work better or worse, and others can change how safe it is or how much of it you need.
Dr. Wallerstorfer
Pharmacogenetics
Genetic differences can affect how our bodies respond to medications. Some people’s genes can make a drug work better or worse, change how safe it is, or influence how much of the drug they need. These genetic changes can affect how the body processes medicine, like how quickly it is broken down or how it interacts with cells. For example, a genetic difference might cause a person’s body to break down a drug too fast, making it less effective, or too slowly, increasing the risk of side effects. This is why people can have different reactions to the same medication.
