Gutiérrez-Gil et al. (2007): c.64G>A Jolly et al. (2008): c.50_52delTTC Laible et al. (2021): "To better adapt dairy cattle to rapidly warming climates, we aimed to lighten their coat color by genome editing. ... Using gRNA/Cas9-mediated editing, we introduced a three bp deletion in the pre-melanosomal protein 17 gene (PMEL) proposed as causative variant for the semi-dominant color dilution phenotype observed in Galloway and Highland cattl...

By cloning and sequencing a very likely comparative candidate gene (based on the homologous human disorder), Dennis et al. (2000) identified two causal mutations in Brahman cattle, namely a frameshifting 2-bp deletion (c.1057delTA; the "E7" mutation) and a nonsense mutation (c.1783C>T; p.Arg595Ter; the "E13" mutation) in the bovine GAA gene; and a 2-bp frameshifting deletion (c.2454delCA; the "E18" mutation) in Shorthorns.

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,...

Bourneuf et al. (2017) detected COL6A3 g.117453719G>A; p.T1894M; omia.variant:1184 as a de novo recessive potentially lethal mutation from an analysis of whole-genome-sequence of a Holstein AI bull. No information was provided on the descendants of this bull.
