UGT1A6 (UDP Glucuronosyltransferase Family 1 Member A6): is a gene that encodes an enzyme from the UDP glucuronosyltransferase family. This enzyme plays a vital role in phase II metabolism by facilitating the conjugation of drugs, toxins, and endogenous substances with glucuronic acid, helping to eliminate them from the body. UGT1A6 is essential for detoxification and maintaining overall metabolic balance.
