An edited linkage map for the AXB and BXA recombinant inbred mouse strains

Area of Science:

• Genetics
• Bioinformatics

Background:

• Recombinant inbred (RI) strains are valuable tools for genetic mapping.
• Previous versions of the AXB and BXA RI strain database required updates due to strain availability and data accuracy.

Purpose of the Study:

• To update and refine the AXB and BXA recombinant inbred (RI) strain database.
• To improve the accuracy and usability of the RI strain data for genetic research.

Main Methods:

• Re-evaluation of strain history and genetic integrity.
• Additional typing of loci and retyping of questionable genotypings.
• Database editing to remove extinct, contaminated, or non-independent strains and loci.

Main Results:

• Reduced the number of independent AXB and BXA RI strains from 51 to 27.
• Updated the strain distribution pattern (SDP) database to include over 700 loci.
• Created two edited versions of the database: one for general use and another optimized for quantitative trait loci (QTL) analysis.

Conclusions:

• The revised AXB and BXA RI strain database provides a more accurate and reliable resource for genetic studies.
• The availability of the edited database facilitates genetic mapping and QTL analysis.
• The updated database enhances the utility of RI strains in genetic research.
