OMIA 002592-9915 : Theileriosis, susceptibility/resistance to in Bos indicus

Mendelian trait/disorder: no

Mode of inheritance: Multifactorial

Considered a defect: yes

Key variant known: no

Cross-species summary: Theileria parva infection, East Coast fever

Inheritance: Wragg et al. (2022) "report on the genetic analysis of a cohort of Bos indicus (Boran) cattle demonstrating heritable tolerance to infection with T. parva (h2 = 0.65, s.e. 0.57)."

Mapping: Wragg et al. (2022): "Through a linkage analysis we identify a 6 Mb genomic region on bovine chromosome 15 that is significantly associated with survival outcome following T. parva exposure. Testing this locus in an independent cohort of animals replicates this association with survival following T. parva infection."

Markers: Wragg et al. (2022): "A stop gained variant in a paralogue of the FAF1 gene in this region was found to be highly associated with survival across both related and unrelated animals ... raising the promise of marker-assisted selection for cattle that are less susceptible to infection by T. parva."

Breed: Boran.
