CYP2D6 is responsible for the metabolism and elimination of approximately 25% of clinically used drugs.

The CYP2A6 enzyme is a part of the Cytochrome P450 (CYPs) family. The CYP family is a group of enzymes that play a major role in detoxification in the body.

The CYP1A2 gene produces the CYP1A2 protein in the liver. This is an important enzyme required to break down toxins of all kinds.

Detoxification is a natural process through which the body removes toxins and other unwanted substances. Detoxification happens regularly to keep the body healthy.

The CYP2C9 enzyme also plays a significant role in the metabolism of warfarin, a blood-thinning drug (anticoagulant) used to prevent clotting inside the blood vessels.

Genetic testing helps understand if you are at risk of high or low CYP2B6 enzyme activity. Smokers may benefit from this information as it can help them know their risk for overexposure to nicotine.
