The application provides an acquiring method and device for
mutation sites of genes corresponding to digestive
system, and relates to the technical filed of biological information. The method comprises the steps of conducting data comparison between a plurality of short sequences of the genes to be tested and the
reference genome to obtain the preliminary variation site information of the genes to be tested; omitting the variation sites which don't meet the preset reservation requirements in the preliminary variation sites according to the preliminary variation site information, and taking the variation sites, obtained after omitted, in the genes to be tested as genes to be inspected; conducting comparison between the genes to be inspected and the multiple
mutation sites of the genes corresponding to the digestive
system in a digestive
system gene pool; obtaining the site
mutation conditions of the genes corresponding to the digestive system in the genes to be tested when the mutation sites which have the same positions and mutation basic groups as the mutation sites in the digestive system
gene pool exist in the genes to be inspected. The acquiring method and device for the mutation sites of the genes corresponding to the digestive system can acquire the mutation conditions of multiple variation sites, in the variation sites of the genes to be tested, corresponding to the digestive system.
