Phenotypes
Cerebellar abiotrophy, CACNA2D2-related
Jacinto et al. (2026): "Genetic analysis [of two affected Angus calvse] identified a private homozygous missense variant [omia.variant:1852] in the bovine CACNA2D2 gene (XP_024839037.1:p.(Cys395Arg)), which is linked to neurological disorders in other species, including a form of cerebellar atrophy in humans."
Chediak-Higashi syndrome
By cloning and sequencing a very likely comparative candidate gene (based on the homologous human disorder), Kunieda et al. (1999) identified a missense mutation (A to G) in the bovine LYST gene, producing an amino-acid substitution of histidine to arginine (H2015R) in the resultant peptide.
Coat colour, dilution, PMEL-related
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...

Lethality, ITGA3-related
Bourneuf et al. (2017) detected ITGA3 g.37219021G>A; p.T252M 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.
Osteopetrosis, SLC4A2-related
