OMIA 001467-9615 : Neuropathy, sensory ataxic in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s) (MIM number): 613561

Mendelian trait/disorder: yes

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2009

Species-specific symbol: SAN

Inheritance: This disorder showed maternal transmission: all affected dogs in a pedigree traced back to a single female, which is consistent with mitochondrial inheritance.

Molecular basis: Baranowska et al. (2009) showed that this disorder is due to a deletion of a single base (at position 5304) in the mitochondrial gene for transfer RNA for the amino acid tyrosine (called tRNA-Tyr).

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.
