NCIt definition : Human CYP1A2*11 allele is located within 15q24 and is approximately 8 kb in length.
This allele, a variant form of the CYP1A2 wild-type allele, encodes cytochrome P450
1A2*11 protein. The CYP1A2*11 allele exhibits a clinically-relevant SNP (g.558C A)
in exon 2 that results in a F186L coding change. This alteration in protein sequence
severely decreases the enzymatic activity of the cytochrome P450 1A2*11 protein.;
