Charlier et al. (2016): splice-site c.826+1G>A

Drögemüller et al. (2011) identified a likely causal variant in Tyrolean Grey cattle as the synonymous c.2229C>T SNP, which "is located within a putative exonic splice enhancer (ESE) and the variant allele leads to partial retention of the entire intron 19 and a premature stop codon in the aberrant MFN2 transcript. Thus we have identified a highly unusual splicing defect, where an exonic single base exchange leads to the retention of the pr...

By whole-genome sequencing of a trio of affected offspring, sire and dam, Jacinto et al. (2022) "identified two heterozygous private protein-changing variants present exclusively in the genome of the affected calf and absent in both parental genomes as well as in 5365 controls . . . . Only one of these variants was in a putative candidate gene for the observed phenotype. This heterozygous variant at chr10:84751870G>A (NM_001101951.1: c.416C...

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,...

On the strength of a clear candidate gene in which mutations cause the same disorder in dogs (OMIA 001003-9615), Boudreaux et al. (2007) reported that this disorder in a Simmental calf is due to a missense mutation (c.701T>C) in the CalDAG-GEFI gene which is now called RASGRP2. Jansen et al. (2013) reported that "Sanger sequencing confirmed that all thrombopathic animals are homozygous for the [same] pertinent amino acid exchange (c.701T &g...
