Abstract
OBJECTIVES: The iPlex® ADME PGx Pro Panel was developed to investigate 191 polymorphisms including single nucleotide polymorphisms (SNPs), insertion-deletions (INDELS), and copy number variations (CNV) relevant for absorption, distribution, metabolism, and excretion (ADME) of drugs. The purpose of this study was to perform a technical evaluation of the iPlex® ADME PGx Pro Panel by genotyping 50 unrelated Danes and estimate preliminary genotype frequencies among Danes. DESIGN AND METHODS: The investigations were performed by the use of PCR, single base extension (SBE) and Matrix Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry (MALDI-TOF-MS). RESULTS: The typing quality of 161 SNP assays was categorized as well performing or acceptable, whereas 22 SNP assays were categorized as either questionable or unacceptable. The frequencies of the genotypes observed in the Danish population were compared to those of the European reference population from the 1000 Genome Project. Three SNPs (rs737865, rs35167514, and rs34305973) showed statistically significantly differences between the frequencies of the 1000 Genomes Europeans and the Danes. The CNV assays could only be used as a guideline. CONCLUSION: In conclusion, the iPlex® ADME PGx Pro Panel is a cost-effective way of genotyping genes relevant for ADME.
