HOMOEOLOGOUS REGION JUDGING METHOD BY HOMO JUNCTION FINGERPRINT METHOD, HOMOEOLOGOUS REGION JUDGING DEVICE, AND GENE SCREENING METHOD

摘要

[PROBLEMS] To provide a method for efficiently searching for a recessive disease gene without needing any pedigree analysis. [MEANS FOR SOLVING PROBLEMS] In a homoeologous region judging method, the following steps are conducted. It is judged 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 judged as homojunctions continue is acquired. If the continuous probability and/or continuous distance of the polymorphic markers contained in the homojunction region information satisfy a predetermined judgment condition, the homojunction region is judged as a homoeologous region. A homoeologous region judging device and a gene screening method for identifying a disease susceptibility gene from the judged homoeologous region are also provided.
