Batch inter-group comparative analysis method for SNP variation rate

The invention discloses a batch inter-group contrastive analysis method for SNP variation rate. The method comprises the following steps: case grouping: dividing case groups into case groups and control groups according to a collection and arrangement standard; in-group SNP variation data integration: a VCF file stores variation results obtained after the whole sequencing data of the case group and the control group are compared with reference genes, and the SNP variation data of the case group and the SNP variation data of the control group are integrated respectively; calculating the variation number of each SNP in the integrated data; and calculating the variation number of each SNP variation of the case group and the control group in each group. The genetic disease/character susceptible gene is found through genome SNP variation rate screening, the screening efficiency of the disease risk gene is effectively improved through batch inter-group comparative analysis of the SNP variation rate, the association
