Phenotypes

Hollmann et al. (2017): "Whole genome re-sequencing of one case and four relatives showed a nonsense mutation (g.5995966C>T) in the PZP-like, alpha-2-macroglobulin domain containing 8 (CPAMD8) gene leading to a premature stop codon (CPAMD8 p.Gln74*)".

Using inferred haplotypes from the 1000-bull-genomes project, Hayes et al. (2013) announced the discovery of the likely HH3 causal mutation. Using exome capture and next-gen sequencing, McClure et al. (2014) confirmed and validated Hayes et al. (2013)'s causal mutation mutation as "a non-synonymous SNP (T/C) within exon 24 of the Structural Maintenance of Chromosomes 2 (SMC2) on Chromosome 8 at position 95,410,507 (UMD3.1). This polymorphism ...

For eight of the nine haplotypes with a significant effect on calving rate (see Mapping section), Fritz et al. (2013) searched for causal mutations via whole-genome sequence data from 25 Holstein, 11 Montbéliarde and nine Normande bulls which had made major contributions to their breed. Specifically, they filtered "for mutations that were (a) located at+or –6 Mb from the detected haplotype (b) carried in the heterozygous state by the carrier b...

Besnard et al. (2023) "present a data-mining framework designed to detect recessive defects in livestock that have been previously missed due to a lack of specific signs, incomplete penetrance, or incomplete linkage disequilibrium. This approach leverages the massive data generated by genomic selection. Its basic principle is to compare the observed and expected numbers of homozygotes for sliding haplotypes in animals with different life histo...

Bourneuf et al. (2017) detected SOWAHB g.93487577G>T; p.Q379K as a de novo recessive potentially lethal mutation from an analysis of whole-genome-sequence of a Charolais AI bull. No information was provided on the descendants of this bull.
