AC blood type is a normal blood type and does not increase health risks on its own. AC genotypes can live normal, healthy lives without increased risks of sickness or disease due to their blood type. In this article, we’ll break down the facts about AC genotypes, what they are, and which genotypes make the most compatible matches.

A person who inherits the Hemoglobin A gene from one parent and the Hemoglobin C gene from the other would have the Hemoglobin C gene (AC). This is not a disease, and there are no health risks linked with it. Typically, there are five (5) unique blood genotypes. They’re AA, AS, AC, SS, and SC. While the first two pairs (AA and AS) are typical, AC is uncommon, and the last two (SS and SC) are irregular and aberrant, frequently resulting in sickle cell disease.

People with the AC genotype are considered heterozygous for that gene, meaning they carry two different versions of the allele. This can affect certain traits, like eye color or risk for disease. Often, the dominant allele will determine the trait, but sometimes, both alleles play a role.

For example, if brown eye color is dominant (B) and blue is recessive (b), someone with the Bb genotype would have brown eyes. However, with some genes, like for height or intelligence, both alleles in the heterozygous genotype contribute to the trait. So, someone with the AC genotype may display a mix of traits associated with the A and C alleles.
