Parentage SNP Exchange (GenoEx-PSE)
The International Genotype Exchange Platform (GenoEx) was established at the Interbull Centre in June 2018 to facilitate genetic information exchange. It includes two databases: GenoEx-PSE and GenoEx-GDE.
GenoEx-PSE is designed for sharing standardized SNP sets for genotyped animals, aimed at streamlining parentage analysis by organizations focused on parentage integrity. It functions as a "bucket" where only authorized parties can upload and access parentage SNPs.
This service does not perform parentage analyses or provide easy access to SNPs for new entrants, and it does not replace national authorities or established parentage verification providers.
GenoEx-PSE is a SNP exchange only for parentage analysis. GenoEx-PSE enables exchange of standardised sets of SNPs for genotyped animals to facilitate and streamline parentage analysis activities carried out by authorised users of the service. National Genetic Evaluation Centres (NGECs) or other relevant organisations in respective countries are responsible for their official parentage verification services.
Animals targeted for routine uploading via GenoEx-PSE are:
- AI sires and their dams
- Foreign-born sires with daughters born in the relevant country
- Parents of animals born by embryo transfer (ET)
- Other special cases (as needed)
A defined set of 200 SNPs recommended by ISAG for Parentage Verification can be exchanged via GenoEx-PSE. For Parentage Discovery a set of 354 SNP (in addition to the 200 SNP for Parentage Verification) can also be uploaded.
GenoEx-PSE users can download SNPs in accordance with what they upload:
1. Organisations officially in charge of parentage certification in each of the ICAR member countries, or otherwise traditionally providing parentage certificate.
2. Organisations that in their capacity as the official body in charge of genetic and/or genomic evaluation services.
3. ICAR/ISAG accredited laboratories that are under contract with the organisations identified in 1 or 2 above.
- GenoEx-PSE covers all beef and dairy cattle breeds.
- Parentage verification SNPs (~200)
- Parentage discovery SNPs (~354)
- Access to parentage analysis genotypes for essentially all dams and AI sires and potentially missing genotypes for some sires
- Safe sharing and exchanging genotypes sufficient for parentage analyses but limited enough to prevent unauthorized imputation or other misuse.
- AI bull owners have more accurate identity of progeny in countries importing semen.
- Eliminate costs of genotyping duplication.
- Membership of ICAR or nomination by an ICAR member.
- Valid ICAR Certification for DNA Interpretation Centres (for SNP-based parentage analysis).
