OMIA 001830-9913 : Haplotype with homozygous deficiency HH7, CENPU related in Bos taurus |
Hozé et al. (2020) reported a new haplotype, also named HH7, located in the BTA27 region 13.0-14.4Mb. (The reason for reusing the haplotype ID HH7 for a haplotype different from the one originally reported is explained by Hozé et al. (2020).)
Molecular basis: Hozé et al. (2020) reported a likely causal variant for the new HH7 haplotype as being "a 4-bp deletion (Chr27 g.14168130_14168133delTACT) that affects a highly conserved region among mammals". Prevalence: Hozé et al. (2020) "genotyped the candidate variant in 232,775 Holstein individuals and did not observe any homozygotes, whereas 16 were expected (Poisson P-value = 1.1 × 10−7; allele frequency = 0.8%). In addition, genotyping of 250,602 animals from 19 additional breeds revealed that the mutant allele is restricted to animals of Holstein descent." Breed: Holstein.

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.
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.

991 | Holstein | Abortion due to haplotype HH7 | CENPU | deletion, small (<=20) | Naturally occurring variant | ARS-UCD1.2 | 27 | g.15123637_15123640del | Hozé et al. (2019): "Considering that CENPU is transcribed in the antisense orientation, this mutation is predicted to result in deletion of the nucleotides located at position +3 to + 6 bp after the splicing donor site of exon 11. Using cross-species nucleotide alignment, we observed that the nucleotide at position +3 is entirely conserved among vertebrates . . . , which suggests that it plays an important role in regulation of CENPU splicing. If modified after exon 11, the abnormal splicing of CENPU could cause mRNA decay or the production of a protein modified after residue 319 out of 409 AA. Based on these factors, we assumed that mutation g.14168130_14168133delTACT on chromosome 27 alters the splicing of CENPU and is embryonic lethal." | 2020 | 31733857 |
