Abstract:
Objective:To identify the polymorphisms of cytochrome P450 3A5 gene (CYP3A5) and multidrug resistance gene 1 (MDR-1) and their distributions in Hans renal transplant recipients in Hunan province, we analyzed the difference of the gene polymorphisms and distributions between Hunan province and 11 other provinces of China.
Methods:We collected 598 Hans renal transplant recipients who had operation or follow-up examination in 3rd Xiangya Hospital from Hunan province. We examined the gene polymorphisms of CYP3A5 and MDR-1 and compared their distributions with the data from 11 other provinces of China by chi-square test.
Results:hTere were CYP3A5*1/*1 genotype in 58 cases (9.7%), CYP3A5*1/*3 genotype in 251 cases (42.0%), CYP3A5*3/*3 genotype in 289 cases (48.3%);MDR-1 3435CC genotype in 238 cases (39.8%), MDR-1 3435CT genotype in 263 cases (44.0%), MDR-1 3435TT genotype in 97 cases (16.2%). Frequency of CYP3A5*1/*1 and*1/*3 genotypes of Hunan province was higher than the that from the 11 other provinces of China and the frequency of mutator*3 was lower. Frequency of MDR-1 3435CC and 3435CT genotypes of Hunan province was higher and the frequency of mutator T was lower than that from the 11 other provinces of China.
Conclusions:There were significant difference in gene polymorphisms and distributions of CYP3A5 and MDR-1 between Hunan province and the 11 other provinces of China. It may be a guideline for us to use calcineurin inhibitor drugs in the early stage atfer renal transplantation.
