UGT1A6 (UDP Glucuronosyltransferase Family 1 Member A6): is a gene that encodes an enzyme from the UDP glucuronosyltransferase family. This enzyme plays a crucial role in phase II metabolism by aiding the conjugation of drugs, toxins, and endogenous substances with glucuronic acid, assisting in their elimination from the body. UGT1A6 is vital for detoxification and sustaining overall metabolic balance.
