Remarks

Donor subject is heterozygous for a variant CYP2D6 gene (CYP2D6*2) which contains two amino acid substitutions: a C>T transition at nucleotide 2938 in exon 6 resulting in an arg296-to-cys [Arg296Cys (R296C)] and a G>C transversion at nucleotide 4268 in exon 9 resulting in a ser486-to-thr [Ser486Thr (S486T)]

Allelic Variant 1

Identified Mutation

ARG296CYS AND SER486THR; This allelic variant is also known as CYP2D6*2 or CYP2D6L. In a family in which 2 sibs and their father had MRs of less that 0.02 (ultrarapid phenotype, see 608902), Johansson et al. (Proc Nat Acad Sci 90:11825-11829, 1993) found 12 extra copies of the CYP2D6 gene inherited in an autosomal dominant pattern; in a second family in which 2 sibs had MRs of less than 0.1, the authors found 2 extra copies of the CYP2D6 gene. All affected individuals had a variant CYP2D6 gene, termed CYP2D6L, which contained 2 amino acid substitutions: a 2938C-T transition in exon 6, resulting in an arg296-to-cys (R296C), and a 4268G-to-C transversion in exon 9, resulting in a resulting in a ser486-to-thr (S486T) substitution. The MR of individuals with 1 copy of the CYP2D6L gene did not differ from those with the wildtype gene, but there was a correlation between decreased MR and increased copies of the CYP2D6L gene.
