“…The greatest contribution to propofol’s individual response is seen in the variants of the CYP2C9 , CYP2B6 , UGT1A9 , SULT1A1 , NQO1 genes, involved in the biotransformation pathway of the anaesthestic and also of transporting proteins: especially P-glycoprotein and serum albumin, encoded by the ABCB1 and ALB genes, as well as the receptor genes GABRA1 and ADRA1A 4 , 9 , 10 . The crucial role can be probably played by three of the genes mentioned above: CYP2B6 (OMIM123930), CYP2C9 (OMIM601130) and UGT1A9 (OMIM606434), coding for metabolizing enzymes: cytochromes P-450 2B6 and 2C9, and UDP-glucuronosyltransferase 1A9, acting mainly in the liver.…”
