OMIA:000129-9940 : Blood group system I in Ovis aries (sheep)
Categories: Haematopoietic system phene
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Considered a defect: no
Key variant known: no
Cross-species summary: Each blood group system consists of a set of blood types, each of which corresponds to a particular antigen (usually a glycoprotein) on the surface of red blood cells. The different types within a system are the result of the action of different alleles at a locus that usually encodes an enzyme that catalyses the creation of the feature of the glycoprotein unique to that type, e.g. the presence of a particular sugar at the end of a short chain of sugars.
Species-specific name: Secretor locus
Species-specific description: This locus has at least 2 alleles, which control the expression of the R blood group system.
Have human generated variants been created, e.g. through genetic engineering and gene editing
