History: Evans et al. (2016) described "a novel NM [nemaline myopathy] in a family of American bulldogs"
Molecular basis: Evans et al. (2016) reported a likely causal variant, namely "a nonsense mutation in NEB (g.52734272 C>A, S8042X) . . . The pathogenic variant was absent from 120 dogs of 24 other breeds and 100 unrelated ABDs, suggesting that it occurred recently and may be private to the family".
Clinical features: Evans et al. (2016): "Affected dogs could independently ambulate, had generalized atrophy, and the myopathy was relatively non-progressive (Supplemental video). Atrophy of the cervical and dorsal thoracic limb muscles was noted with bilateral hypertrophy of the triceps muscles. Serum creatine kinase (CK) activities were mildly elevated. Electromyography (EMG) revealed spontaneous electrical activity, consisting mainly of fibrillation potentials, within the proximal appendicular muscles of the thoracic limbs and the cervical paraspinal musculature. Motor nerve conduction velocity (MNCV) testing showed a mild decrease in the latency of the tibial and ulnar nerves. Respiratory difficulties were not present."
Breed:
American Bulldog (Dog) (VBO_0200034).

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.
