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

Possibly relevant human trait(s) and/or gene(s) (MIM number): 590100 (gene)

Mendelian trait/disorder: yes

Mode of inheritance: Mitochondrial

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).

Breed: Golden Retriever.

Associated gene:
