Cross-species summary: Bleeding disorder due to deficiency of factor VII, a vitamin K–dependent glycoprotein

Molecular basis: By sequencing the most likely candidate gene (based on a prolonged prothrombin time in the presence of a normal partial thromboplastin time) in a single Asian elephant, Lynch et al. (2017) identified the likely causal mutation as "a single homozygous point mutation (c.202A.G) in the F7 gene of the FVII deficient elephant that was not present in unrelated elephants. This mutation causes an amino acid substitution (p.Arg68Gly) that is predicted to be deleterious."

Clinical features: As reported by Lynch et al. (2017), "Consistent with FVII deficiency investigations in other species, the condition did not cause a serious bleeding tendency in this individual elephant".

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.
