Embodiment 1

[0020] Example 1 Screening of the most dangerous genes

[0021] 1) Selected 66 patients with sporadic dilated cardiomyopathy, extracted 3ml of venous blood, and extracted DNA;

[0022] 2) The 24 genes that lead to familial dilated cardiomyopathy were fully sequenced for these patients through the method of next-generation sequencing;

[0023] 3) The sequencing results are: a total of 87 non-synonymous sites were found. In order to clarify whether these sites are mutations, the dbSNP (single nucleotide polymorphism database) and 1000 genomes project of NCBI (National Center for Biotechnology Information) database (Thousand Genomes Project database), and at the same time, 197 Chinese adults from the Thousand Genomes database were used as the same-race control group to calculate the carrying rate of these loci in the database and the control group, and the carrying rate in the case cohort Compare, calculate p-value;

[0024] 4) According to information biology technology, using...

Embodiment 2

[0030] Example 2 Screening Kit

[0031] According to the four "most dangerous genes" obtained in Example 1, the present invention provides a test kit for screening dilated cardiomyopathy, which includes a test kit for human MYBPC3, SCN5A, MYH7 and MYPN Reagents for whole exome sequencing of genes, only for human MYBPC3, SCN5A, MYH7 and MYPN The screening of these four genes can significantly increase the detection rate of patients, greatly save the detection cost, increase the early detection rate, so as to achieve early treatment and improve the survival rate of patients.

Abstract

The invention relates to a kit for screening dilated cardiomyopathy. The following four detection genes are used in the kit: MYBPC3, SCN5A, MYH7 and MYPN. The invention also provides the application of the four genes (MYBPC3, SCN5A, MYH7 and MYPN) in preparing the kit for screening dilated cardiomyopathy. The invention has the following advantages: the effective method and the kit for early diagnosis of sporadic dilated cardiomyopathy in the Han nationality in China are developed by screening the four genes causing sporadic dilated cardiomyopathy which are most susceptible in the Han nationality in China, so that the early screening rate of patients with dilated cardiomyopathy is effectively increased to support early treatment and increase the survival rate of patients; compared with the expensive and low-efficiency dilated cardiomyopathy gene screening method in the prior art, the discovery of the four high-risk pathogenic genes enables the screening to be more targeted, so as to reduce the examination expenses and increase the detection efficiency.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an early diagnosis method and a screening kit effective for sporadic dilated cardiomyopathy in Chinese Han population. Background technique [0002] Dilated cardiomyopathy is one of the most common cardiomyopathies, characterized by enlarged ventricular cavity, decreased myocardial systolic function and normal left ventricular wall thickness. It is the third cause of heart failure and the first cause of heart transplantation. It can be caused by coronary heart disease, myocarditis and systemic diseases, but it can also be primary. The incidence of primary dilated cardiomyopathy is about 40 / 100,000, and the cellular and molecular mechanisms of its pathogenesis are still unclear. About 30% of cases show familial inheritance, and recently we found that 70% of sporadic dilated cardiomyopathy also have multiple gene mutations, suggesting that genetic factors play an important role i...
