Multiplex PCR (polymerase chain reaction) primer set for detection Y chromosome microdeletion, kit and application

Abstract

The invention relates to the field of gene deletion detecting, in particular to a multiplex PCR (polymerase chain reaction) primer set for detection Y chromosome microdeletion, kit and application. The multiplex PCR primer set comprises a universal primer and a specific primer, the universal primer has base sequences shown as SEQ ID NO:1 and SEQ ID NO:2, a 5' terminal of the base sequence shown as the SEQ ID NO:1 is marked with a fluorophore, and the specific primer comprises a primer having base sequences shown as SEQ ID NO:3-SEQ ID NO:22. The defect that conventional multiplex PCR is low in sensitivity and non-specific amplification is overcome; through a method combining a novel stable universal primer-multiplex PCR reaction system with a fluorescent labeling universal primer, an amplification product is subjected to capillary electrophoresis analysis, so that high sensitivity of detection is guaranteed, cost is effectively lowered, and large-sample-size efficient detection can be realized.

Description

technical field [0001] The present invention relates to the field of gene deletion detection, more specifically, to a multiplex PCR primer set for detecting Y chromosome microdeletion, the kit including the multiplex PCR primer set and the multiple PCR primer set and the kit as a method for detecting Y chromosome microdeletion Application of missing reagents. Background technique [0002] According to the research report of the World Health Organization (WHO), about 15% of couples of childbearing age in the world are plagued by infertility (fertility), of which male factors account for about 50%. More than 30% of male infertility is caused by genetic factors, mainly Klinefelter syndrome and Y chromosome microdeletion. Cytogenetic and molecular biology studies have confirmed that microdeletions in the azoospermia factor (AZF) region located on the long arm of the Y chromosome can cause spermatogenesis disorders, leading to azoospermia or severe oligospermia.
