NCIt definition : Human CYP2E1*2 allele is located within 10q24.3-qter and is approximately 12 kb in
length. This allele, a variant form of the CYP2E1 wild-type allele, encodes cytochrome
P450 2E1*2 protein. The CYP2E1*2 allele exhibits a clinically-relevant SNP (g.1132G
A) in exon 2 that results in a R76H coding change. This alteration in protein sequence
severely decreases the enzymatic activity of the cytochrome P450 2E1*2 protein.;
