NAT2 Genotype details
What NAT2 Genotype shows
NAT2 is a gene that makes an enzyme called N-acetyltransferase 2, which helps your liver process certain medicines and chemicals by a step called acetylation. Medicines affected include isoniazid, used for tuberculosis, and hydralazine, used for blood pressure. This test identifies the NAT2 variants you carry in DNA from your blood. The result is a lifelong genetic variant, not a level that changes. Some combinations of variants slow acetylation, which can raise drug levels and the chance of side effects. Your genotype is used to predict your acetylator phenotype, and any medicine decisions are made by your prescriber.
Tests that include NAT2 Genotype
Pharmacogenomics Panel reporting genotype/phenotype only. Genetics can play a significant role in the selection of certain medications. For instance, individuals may metabolize medications too fast or too slow. This test analyzes genes of known pharmacogenomic value allowing clinicians to gain valuable insight into an individual's response to and adverse effects from medications with known gene-drug interactions. For reporting that includes medication guidance please reference: Pharmacogenomics panel with Coriell Life Sciences (CLS) Report, test code 14271.
