Molecular basis: By sequencing a likely candidate gene (based on clinical signs and pathology) in a single German Shepherd Dog that had been euthanased five years previously), Boudreaux et al. (2010) reported that a "12-base pair insertion was identified in the coding region for KINDLIN3 in the affected dog but not in the canine genome sequence or the control dog sequences. This mutation is predicted to result in the insertion of amino acids RRLP within an alpha helix located in the Kindlin-3 pleckstrin-homology domain of the F2 band 4.1, ezrin, radixin, moesin (FERM) subdomain". The KINDLIN3 gene is now known as FERMT3 (fermitin family member 3).

Clinical features: Key clinical signs include pyrexia, bleeding diathesis, and dental disease (Hugo & Heading, 2014; Boudreaux et al.,2010). Other signs may include joint effusions (Hugo & Heading, 2014), lameness, and infections, such as pododermatitis, deep pyoderma, and cellulitis (Boudreaux et al., 2010). Bleeding diathesis has been noted to occur following injury or surgery (Boudreaux et al., 2010; Hugo and Heading, 2014). Affected dogs have persistent leukocytosis and neutrophilia (Hugo & Heading, 2014; Boudreaux et al., 2010). Assays of haemostasis may yield variable results, including prolonged buccal mucosal bleeding times, normal coagulation screening assays and vWF antigen concentration, and delayed platelet aggregation and clot retraction (Hugo & Heading, 2014; Boudreaux et al., 2010).

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.
