Phenotypes

Splicing variant 10 bp upstream of the intron1/exon 2 boundary (c211-10C>G) at position 79,814,520 (Bos taurus assembly: BosTau6/UMD3), leading to skipping of exon 2 (Sartelet et al., 2015)

Khalaj et al. (2009): "A nucleotide substitution of T to A resulting in an amino acid substitution of leucine to histidine (p.Leu2153His) was identified in a highly conserved residue in the C1 domain of factor VIII. Genotyping of 254 normal animals including the pedigree of the affected animals and randomly sampled animals of different breeds confirmed that the substitution is the causative mutation of cattle haemophilia A." Analysis of whole-...

Häfliger et al. (2021) investigated “the two Braunvieh populations reared in Switzerland, the dairy Brown Swiss (BS) and the dual-purpose Original Braunvieh (OB). We performed a genome-wide analysis of array data of trios (sire, dam, and offspring) from the routine genomic selection to identify candidate regions showing missing homozygosity and phenotypic associations with five fertility, ten birth, and nine growth-related traits. In addition,...

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...

Shan et al. (2020) reported "a Holstein sire named Tarantino who had been approved for artificial insemination that is based on normal semen characteristics (i.e., morphology, thermoresistance, motility, sperm concentration), but had no progeny after 412 first inseminations".

Jacinto et al. (2021) characterized "the pathological phenotype of a Romagnola stillborn calf with skeletal-cardio-enteric dysplasia and ... [identified] a genetic cause by whole-genome sequencing (WGS)."
