Determination of CYP2D6 gene copy number by pyrosequencing.
BACKGROUND Identification of CYP2D6 alleles *5 (deletion of the whole CYP2D6 gene) and *2xN (gene duplication) is very important because they are associated with decreased or increased metabolism of many drugs. The most commonly used method for analysis of these alleles is, however, considered to be laborious and unreliable. METHODS We developed a method to determine the copy number of the CY...
متن کاملDetermination of Cytochrome P450 2D6 (CYP2D6) Gene Copy Number by Real-Time Quantitative PCR
Gene dosage by real-time quantitative PCR has proved to be accurate for measuring gene copy number. The aim of this study was to apply this approach to the CYP2D6 gene to allow for rapid identification of poor and ultrarapid metabolizers (0, 1, or more than 2 gene copy number). Using the 2(-Delta Delta Ct) calculation method and a duplex reaction, the number of CYP2D6 gene copies was determined...
متن کاملSimple copy number determination with reference query pyrosequencing (RQPS).
The accurate measurement of the copy number (CN) for an allele is often desired. We have developed a simple pyrosequencing-based method, reference query pyrosequencing (RQPS), to determine the CN of any allele in any genome by taking advantage of the fact that pyrosequencing can accurately measure the molar ratio of DNA fragments in a mixture that differ by a single nucleotide. The method invol...
متن کاملRapid identification of homologous recombinants and determination of gene copy number with reference/query pyrosequencing (RQPS).
Manipulating the mouse genome is a widespread technology with important applications in many biological fields ranging from cancer research to developmental biology. Likewise, correlations between copy number variations (CNVs) and human diseases are emerging. We have developed the reference-query pyrosequencing (RQPS) method, which is based on quantitative pyrosequencing and uniquely designed p...
متن کاملCYP2D6 genotyping for functional-gene dosage analysis by allele copy number detection.
BACKGROUND Cytochrome P450 2D6 (CYP2D6), one of the most important drug-metabolizing enzymes, has been reported to possess variation in the encoding CYP2D6 gene (cytochrome P450, family 2, subfamily D, polypeptide 6) that affects enzymatic activity. For the pharmacogenetic study of CYP2D6, accurate measurement of the dosage of the functional gene is essential; however, current genotyping techni...
