What is an Alternative Allele?

An alternative allele is a version of a gene that differs from the most common form found in the population. It's simply one of the possible genetic variants you can inherit from your parents.

You inherit two copies of each gene — one from each parent — and each copy can be a different allele. These alleles influence how a gene functions and, in some cases, how it relates to your health.

How Alternative Alleles Can Affect Health

Some alternative alleles are associated with:

  • Increased risk for certain health conditions
  • Decreased risk or protective effects
  • No noticeable impact at all

For example, a gene related to heart health may have multiple alleles — one associated with higher disease risk and another that may be associated with lower risk.

Looking at the Bigger Picture

Your overall health profile isn't determined by a single allele. It's shaped by the combination of alleles you carry across many genes. Several alleles associated with higher risk may raise your susceptibility for certain conditions, while more protective alleles may lower your risk in specific health areas.

This is why SelfDecode evaluates many genes together — to give you a complete and balanced view of how your genetics may influence your health.
