Method and system of replacing missing genotyping data

摘要

A system and method of replacing a missing genotyping data are provided. The method includes: constructing a sample group consisting of a genotyping data with respect to SNP sites of at least one gene samples; comparing a similarity between a sample of the sample group having a missing genotyping data of an SNP site with the other samples of the sample group, and selecting a predetermined number of the samples in order of high similarity; and checking a genotyping data having a greatest frequency occurring in an SNP site disposed at the same position as the SNP site having the missing genotyping data among the selected samples, and replacing the missing genotyping data with the genotyping data having the greatest frequency. It is possible to prevent an incorrect analysis result due to data mismatch, which is caused by data loss.
