Abstract:
The present invention relates to an apparatus for predicting the risk of disease of a user based on single nucleotide polymorphism (SNP) combination related to the target disease. The apparatus comprises a whole genome analysis-based disease related database saving the relation between the disease and SNP combinations extracted from a disease group and a control group based on the whole genome analysis information thereof; and an SNP combination extraction part filtering the target disease related SNP data from the disease related database in stages according to priority and conducting the following stage of filtering based on error rates of candidate SNP combinations generated from each stage of filtering, and extracting a candidate SNP combination showing the lowest error rate as the target disease related SNP combination.
