UGT1A1 is a polymorphic enzyme that has been associated with irinotecan drug metabolisms. We developed a pyrosequencing method to detect allele frequency and genotype of UGT1A1 polymorphisms (UGT1A128 and UGT1A16) in Thai colorectal cancer patients.
A pyrosequencing method was designed to determine UGT1A1 genetic polymorphisms including UGT1A128 (A[TA]7TAA) and UGT1A16 (211G>A) in 91 Thai colorectal cancers.
Genotyping by the pyrosequencing technique was 100% concordant with capillary electrophoresis sequencing. The allele frequencies for UGT1A1 genetic polymorphisms were *1/*1 (54.95%), *1/*6 (13.19%), *1/*28 (25.27%), *28/*6 (4.40%), and *28/28 (2.20%). No homozygous mutation UGT1A16 was found in our population.
We developed a rapid, reliable, more cost-effective, and simple assay to detect UGT1A1 genetic polymorphisms in routine practice before initiating irinotecan therapy. The UGT1A128 and UGT1A16 alleles were found to be similar in the Asian populations.
UGT1A1 是一种多态酶,与伊立替康药物代谢有关。我们开发了一种焦磷酸测序法来检测泰国结直肠癌患者 UGT1A1 多态性(UGT1A128 和 UGT1A16)的等位基因频率和基因型。
设计了一种焦磷酸测序法来确定 UGT1A1 遗传多态性,包括 91 例泰国结直肠癌患者中的 UGT1A128(A[TA]7TAA)和 UGT1A16(211G>A)。
焦磷酸测序技术的基因分型与毛细管电泳测序完全一致。UGT1A1 遗传多态性的等位基因频率为*1/*1(54.95%)、*1/*6(13.19%)、*1/*28(25.27%)、*28/6(4.40%)和28/28(2.20%)。我们的人群中未发现 UGT1A16 纯合突变。
我们开发了一种快速、可靠、更具成本效益和简单的检测方法,用于在开始伊立替康治疗前在常规实践中检测 UGT1A1 遗传多态性。UGT1A128 和 UGT1A16 等位基因在亚洲人群中相似。
