Distribution of the cytochrome P450 *alleles for CYP2C9 and CYP2C19 in a cohort of the Danish Blood Donor Study determined by using the Illumina Infinium Global Screening Array.

This article presents a study on the distribution of cytochrome P450 (CYP450) alleles in the Danish population. CYP450 enzymes are important for drug metabolism, and genetic variations in the genes encoding these enzymes can impact drug response. The study compared genotype data from different genotyping platforms and found that the CYP2C19*17 and CYP2C9*2 alleles were more common than the CYP2C19*2 and CYP2C9*3 alleles. The results provide valuable insights into the genetic variability of these enzymes in the Danish population and suggest that the Illumina GSA platform could be useful for identifying drug-gene interactions.
