Homoeologous Region Determining Method by Homo Junction Fingerprint Method, Homoeologous Region Determining Device, and Gene Screening Method

摘要

To provide a method for efficiently searching for a recessive disease gene without needing any pedigree analysis. In a homoeologous region determining method, the following steps are conducted. It is determined whether or not the base constituting a polymorphic marker of a sample DNA of diploid or higher polyploidy is a homojunction. Homojunction region information representing the region of the sample DNA where polymorphic markers determined as continuous homojunctions acquired. If the continuous probability and/or continuous distance of the polymorphic markers contained in the homojunction region information satisfy a predetermined determination condition, the homojunction region is determined as a homoeologous region. A homoeologous region determining device and a gene screening method for identifying a disease susceptibility gene from the determined homoeologous region are also provided.
