Abstract

The invention discloses a kit and method for detecting gene polymorphism of an irinotecan personalized medicine by a pyrophosphoric acid sequencing method. The kit is used for parting an irinotecan medicine gene, particularly single nucleotide polymorphism of UGT1A1*6 (rs4148323) and UGT1A1*28 (rs3064744). The kit comprises primers shown as SEQ ID NO. 3-8. According to the kit, accurate, quick and high-flux detection of the UGT1A1*6 (rs4148323) and the UGT1A1*28 (rs3064744) can be realized, so that individual administration for realizing safe, rational and effective irinotecan medicine is achieved.

Description

technical field [0001] The invention belongs to the field of molecular biology, and in particular relates to a kit and a method for detecting gene polymorphism of irinotecan individualized medicine by pyrosequencing. Background technique [0002] Irinotecan is a camptothecin prodrug, which can be metabolized into the active form 7-ethyl-10-hydroxycamptothecin (SN-38) by carboxylesterase in vivo. The target of SN-38 is DNA topoisomerase I, which can interfere with DNA replication and transcription, can inhibit DNA synthesis, and has strong tumor-killing activity. It is widely used in the treatment of solid tumors such as gastric cancer, colorectal cancer, and lung cancer, and can significantly improve the overall survival of patients. However, when irinotecan is used, the incidence of serious side effects is high, especially severe delayed diarrhea and agranulocytosis, which affect its clinical application. Clinical studies have shown that more than 40% of patients receivin...
