Problems solved by technology

This method has no advantages for the detection of no clear candidate genes, a large number of candidate genes, and a large number of samples
At the same time, for Sanger sequencing, the sequencing fragments are short, and mutation types such as large fragment deletions and copy number variations cannot be detected, resulting in omission of detection results

Embodiment 1

[0063] The DNA sequence of the SERPINF1 gene (NG_028180.1) was analyzed according to the NCBI GeneBank database, and the amplification primers for exons 1 to 8 were designed. The amplified region includes all exons of SERPINF1 and the intron sequence at the junction of exons and introns not less than 50 bp. The nucleotide sequences of primers used in PCR amplification are shown in Table 1.

Abstract

The invention provides a primer set for detecting a human SERPINF1 gene mutation and a kit thereof. The invention belongs to the technical field of gene detection. The kit for detecting the human SERPINF1 gene mutation comprises a PCR amplification primer set which is used for detecting the SERPINF1 gene mutation and consists of first to eighth exons, a PCR amplification reagent, a PCR product purification reagent and a sequencing reagent containing the sequencing primer set for detecting the SERPINF1 gene mutation. The kit provided by the invention carries out mutation detection for the firstto eighth exons of an SERPINF1 gene and ensures accuracy and specificity of a measurement result. The primer set can be used for detecting the SERPINF1 gene mutation of a VI type osteogenesis imperfect (OI) patient, and the SERPINF1 gene mutation comprises a homozygous mutation, a compound heterozygous mutation and the like. Meanwhile, the primer set can also be used for screening VI type OI carriers and detecting complex disease lesions possibly caused by the gene mutation.

Description

technical field [0001] The invention belongs to the technical field of gene detection, and in particular relates to a primer set and a kit for detecting human SERPINF1 gene mutation. Background technique [0002] Osteogenesis imperfecta (OI) is a rare hereditary connective tissue disease caused by collagen synthesis disorder. The main clinical phenotypes include osteoporosis and increased bone fragility, blue sclera, dentin insufficiency, and premature otosclerosis. Osteogenesis imperfecta has genetic heterogeneity, including autosomal dominant inheritance, autosomal recessive inheritance, and X-linked inheritance. More than 80% of patients have mutations in the type I collagen structural gene COLIAl or COLIA2. Caused by autosomal dominant inheritance. Osteogenesis imperfecta type VI is an autosomal recessive disorder caused by mutations in the SERPINF1 gene. The protein encoded by the SERPINF1 gene is pigment epithelium-derived factor (PEDF), which is a secreted glycopro...
