OMIA 000361-9783 : Factor VII deficiency in Elephas maximus

In other species: dog

Possibly relevant human trait(s) and/or gene(s) (MIM number): 227500

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2017

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".

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.
