Abstract
The invention provides an endometrial polyp methylation marker combination for the first time. The endometrial polyp methylation marker combination comprises the following gene markers: IGF1R, CTBP1, TCF7L1, E2F3, CACNA2D4, KCNJ12, TPO, UGT1A8, UGT1A10, CABP5, CST9, ITGA2, DLGAP2, ESPNP, NBPF25P, RASA3, ZIM2, PXDN, HDAC4 and VAV2; the endometrial polyp can be effectively diagnosed by detecting the methylation level of the gene markers in a sample to be detected from a subject, the specificity reaches 87.27%, and the sensitivity reaches 91.11%.
Description
technical field [0001] The invention relates to the field of medical diagnosis, and more specifically, to a combination of endometrial polyp methylation markers, a detection kit and applications. Background technique [0002] Endometrial polyps (endometrial polyps) is a common disease in gynecology, which is caused by local excessive hyperplasia of endometrium, manifested as single or multiple smooth masses protruding from the uterine cavity, with different pedicles; Vaginal bleeding, infertility. Women from childbearing age to postmenopausal women are all high-risk groups of endometrial polyps. The probability of women suffering from endometrial polyps in their lifetime is about 70%. Among these patients, about 15% occur in the reproductive age stage. Endometrial polyps in the reproductive age stage may lead to infertility. [0003] Commonly used examination methods for endometrial polyps are gynecological examination, ultrasonography, hysteroscopy, and pathological exami...
