GenoChip CYP2D6 macroarray as a method to genotype for CYP2D6 variants: results of a validation study in a Caucasian population.
OBJECTIVE
The aim of this study was to investigate the concordance between the novel GenoChip CYP2D6 macroarray and the AmpliChip, which is considered the gold standard in CYP2D6 genotyping.


METHODS
Germline DNA of 200 patients was genotyped with both the AmpliChip and the GenoChip CYP2D6 macroarray.


RESULTS
One hundred and ninety-eight samples (99%) showed concordance. In two discordant samples the AmpliChip identified a *41 allele while the GenoChip CYP2D6 macroarray did not. Sanger sequencing showed that the 2988G>A mutation and thus the *41 allele was not present in both samples.


CONCLUSIONS
We conclude that that the GenoChip CYP2D6 macroarray is a valid method for detecting genetic variants of CYP2D6 in a Caucasian population. Original submitted 10 November 2014; Revision submitted 23 February 2015.
