Phenotypes
Anhidrotic ectodermal dysplasia, EDAR-related
Bourneuf et al. (2017): a de novo likely causal variant in Charolais is single-base insertion in EDAR, resulting in a frameshift variant g.44462236_44462237insC; p.P161RfsX97
Chondrodysplasia, EVC2-related — bovine chondrodysplastic dwarfism, bcd
Also known as Ellis-van Creveld Syndrome
Citrullinaemia
To date, all cases of this lethal disorder in cattle appear to be due to the same mutation, namely a nonsense mutation in the 5th of 9 exons of the ASS gene. Normal bovine ASS is a peptide containing 412 amino acids; the mutation occurs in the 86th codon.
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...
Dwarfism, ACAN-related — Bulldog calf; chondrodysplasia
Information about ACAN related dwarfism in Bos indicus cattle was previously listed here and was moved to 'OMIA:001271-9915 : Dwarfism, ACAN-related in Bos indicus' [19/06/2023]
Glycogen storage disease II
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.
Hairy — slick
By sequencing the most likely functional positional candidate gene from the mapped region (see Mapping section), Littlejohn et al. (2014) identified a causal mutation as a "nonsynonymous SNP in exon 5 [that] encodes a p.Cys221Gly substitution highly conserved across vertebrates and other structurally related hormones, disrupting one of three disulphide bonds defining the three-dimensional (3D) structure of mature prolactin hormone" (ss10672894...
