Abstract

The purpose of this study is to investigate the genotype and allelic frequencies of CYP3A in Bangladeshi Tuberculosis (TB) patients which may help for individualized drug dosing and improved therapeutics. Genotyping was done using the extracted genomic DNA from 90 TB patients followed by amplification of target alleles by PCR. Amplified alleles were then digested by restriction enzymes followed by gel electrophoresis & sequencing to identify the targeted alleles namely CYP3A4*1B, CYP3A4*2, CYP3A4*4, CY3A4*5, CYP3A4*6, CYP3A4*10, CYP3A4*18, and CYP3A5*3. In TB patients, no samples were positive for CYP3A4*2, CYP3A4*4, CYP3A4*5, CYP3A4*6, CYP3A4*10, and CYP3A4*18 alleles. One sample was found to be heterozygous for CYP3A4*1B (1.11%). The wild homozygous (CYP3A5*1/*1) genotype frequency was 7.78%, the heterozygous (CYP3A5*1/*3) frequency was 42.22% and the homozygous mutant (CYP3A5*3/*3) frequency was 50% in Bangladeshi TB patients. The absence of the common polymorphic gene suggests that there will be no impact of CYP3A drug metabolizing enzymes on antituberculosis drugs.
