Coat colour, white spotting, KIT-related — Hereford pattern or white headed, as well as spotting
Fontanesi et al. (2010): "[V]ariation in the white spotting in several cattle breeds is largely influenced by the multiple allelic series at the S locus, which includes at least four alleles (Olson 1999): SH (Hereford pattern), SP (Pinzgauer pattern or lineback), S+ (non-spotted) and s (spotting pattern). The SH allele gives white face, belly, feet and tail, often with a white stripe over the shoulder when homozygous. The SP allele gives pigm...
Haplotype with homozygous deficiency NH7, CAD-related
Mesbah-Uddin et al. (2019) reported a likely causal variant as a "missense mutation CAD g.72399397T>C (p.Tyr452Cys)"
Haplotype with homozygous deficiency, RFC5-related
Besnard et al. (2023) "present a data-mining framework designed to detect recessive defects in livestock that have been previously missed due to a lack of specific signs, incomplete penetrance, or incomplete linkage disequilibrium. This approach leverages the massive data generated by genomic selection. Its basic principle is to compare the observed and expected numbers of homozygotes for sliding haplotypes in animals with different life histo...
Osteogenesis imperfecta, type II, COL1A1-related
Bourneuf et al. (2017): a de novo likely causal variant is COL1A1 p.1049_1050delinsS in Fleckvieh Petersen et al. (2019): "Whole-genome sequencing revealed the presence of a missense mutation in the alpha 1 chain of collagen Type I (COL1A1), for which both calves were heterozygous. The variant resulted in the substitution of a glycine residue with serine in the triple helical domain of the protein; in this region, glycine normally occupies eve...
Retinitis pigmentosa 1
Michot et al. (2016): "a one base pair insertion (Chr14: g.23995411_23995412insA) that affects the retinitis pigmentosa-1 gene (RP1) . . . [and] is predicted to cause a frameshift at codon 791 and to terminate the protein 13 amino acids later (p. R791KfsX13)".
