WebSep 30, 2024 · The CYP3A7*1C allele thus possesses the transcription binding site CYP3A4-ER6 which has a higher affinity for PXR and CAR, resulting in a significant expression of CYP3A7 well into adulthood [47]. In general, CYP3A7*1C allele frequencies range from approximately 1.7%–6% depending on the ethnic group being considered … WebCYP3A7 mRNA is polymorphically expressed in both liver and intestine, with 11% of subjects belonging to a distinct sub-group of high expression phenotype. Two-thirds of the subjects in this group carry the CYP3A7*1C or (less frequently) the CYP3A7*1B promoter allele. The CYP3A7*1C allele is the ex-clusive marker of high CYP3A7 expression in the ...
