Cross-species summary: Also called factor VIII deficiency. Impaired coagulability of the blood, with a consequential strong tendency to bleed, due to a deficiency of clotting factor VIII. Since the gene for this factor is located on the X chromosome, the disorder is expected to be X-linked. As with haemophilia B, this expectation has been confirmed in all species of mammal in which the disorder has been reported. In humans, there are hundreds of different mutations that give rise to haemophilia A. In domesticated animals, the disorder has been reported in a large range of species.

Molecular basis: Khalaj et al. (2009): "A nucleotide substitution of T to A resulting in an amino acid substitution of leucine to histidine (p.Leu2153His) was identified in a highly conserved residue in the C1 domain of factor VIII. Genotyping of 254 normal animals including the pedigree of the affected animals and randomly sampled animals of different breeds confirmed that the substitution is the causative mutation of cattle haemophilia A." Analysis of whole-genome sequence from a German Fleckvieh bull affected with a mild form of this disorder and from 19 non-affected cattle from other breeds enabled Reinartz et al. (2018) to identify a likely causal missense variant, namely ss213751737:g.38842314A>T; p.His45Leu in the F8 gene. A synonymous variant ss2137517373:g.38884774G>A; p.Ala361Ala was in complete disequilibrium with the former variant.

Prevalence: Reinartz et al. (2018): "The frequency of the mutant alleles T and A were 6/121 chromosomes in the herd of origin."

Breeds: Fleckvieh-Simmental, Germany (Cattle) (VBO_0002354), Japanese Brown, Japan (Cattle) (VBO_0004988).
Breeds in which the phene has been documented. (If a likely causal variant has been documented for the phene, see the variant table breeds in which the variant has been reported).

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.
