Species-specific name: Haplotype JH1
Species-specific symbol: JH1
Mapping: Using genotype data from tens of thousands of North American Holsteins, Jerseys and Brown Swiss cattle each genotyped with approximately 50K SNPs on the BovineSNP50 BeadChip, VanRaden et al. (2011) identified five new recessive lethal haplotypes by searching for common haplotypes that are never homozygous in live animals. One of these haplotypes occurs in Jerseys only, and (following a convention proposed by breed-association staff) VanRaden et al. (2011) named it JH1, where J stands for Jersey and H for haplotype. It maps to chromosome BTA15, at 13-18Mb (UMD 3.0 genome assembly).
Molecular basis: 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-to-T transition SNP results in an Arginine to a stop codon in exon 3 of CWC15, the bovine protein CWC15 homolog of a spliceosome-associated protein . . . . This nonsense mutation would reduce the size of the CWC15 protein product from 231 amino acids in length to only 54 amino acids. A NCBI conserved domains search on the bovine CWC15 protein product reveals that this truncated protein would not have the conserved Cwf_Cwc_15 (pfam04889) domain present in the wildtype."

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
