OMIA 001130-9615 : Leucodystrophy in Canis lupus familiaris

In other species: American mink

Mendelian trait/disorder: yes

Mode of inheritance: Mitochondrial

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2006

Species-specific name: canine spongiform leukoencephalomyelopathy

Molecular basis: Li et al. (2006) showed that this disorder is due to a missense variant in the mitochondrial gene for cytochrome b. The variant is a G>A transition as position 14,474 of the mitochondrial genome (NC_002008) predicted to result is a p.V98M substitution on the protein level. This is the first report in domesticated animals of a naturally-occurring base substitution in a mitochondrial gene, leading to an inherited disorder

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.
