Haplotype with homozygous deficiency JH1 — Haplotype JH1
Sonstegard et al (2013) investigated the lethal Jersey haplotype, namely haplotype JH1 on chromosome BTA15 (see Mapping section). They first refined the haplotype "to a 15-marker window (15,162,470 to 15,949,175)" and then obtained whole-genome sequence from 11 bulls carrying this haplotype. Analysis of the sequence of these carriers in the candidate region revealed a "high-impact stop-gain SNP located at position 15,707,169 on BTA15. This C-t...

Sieck et al. (2020): "Whole-genome sequencing (WGS) of 20 animals [including 3 affected calves] led to the discovery of a variant (Chr26 g. 14404993T>C) in Exon 3 of CYP26C1 associated with MD. This missense mutation (p.L188P), is located in an α helix of the protein, which the identified amino acid substitution is predicted to break"
