Phenotypes
Ataxia and dyslipidemia, LIPC-related
Weber et al. (2026) investigated an inherited neuromuscular disorder in Brown Swiss cattle. Use of whole genome sequencing resulted in the identification of a "rare homozygous missense variant in LIPC (chr10:51715800G>C; NM_001035410.1:c.924C>G; p.Phe308Leu; omia.variant:1842) ... and in-silico predictions classified this variant as deleterious. Population-level genotyping of over 20.000 BS cattle revealed a variant allele frequency of 1...
Brachygnathia, WNT10B-related
Widmer et al. (2023): "A breed specific frameshift duplication in WNT10B (rs525007739; c.910dupC; p.Arg304ProfsTer14) ... was found to be associated with a 21.5-fold increased risk of brachygnathia inferior in homozygous [Brwon Swiss] carriers."
Hemimelia, tibial

Ichthyosis, ABCA12-related
In the words of Charlier et al. (2008): "a missense mutation in exon 39 (A5804G) resulting in an H1935R substitution in the fourth extracellular loop". The His (normal) form of the peptide is conserved in all vertebrates sequenced to date. (FN 080330) Whole-genome sequencing of the affected Shorthorn calf described by O'Rourke et al. (2017), and subsequent checking for deleterious variants in functional candidate genes, enabled Woolley et al. ...
Trimethylaminuria (fishy taint)
In a neat piece of comparative detective work, Lunden et al. (2002; Genome Research 12:1885-1888) investigated whether the fishy off-flavour occasionally reported in cow's milk could be an animal model of fish-odor syndrome in humans, an inborn error of metabolism characterised by a fishy body odor, and known to be due to mutations in the gene for flavin-containing mono-oxygenase 3 (FMO3). They were able to show that this is, indeed, the case:...
