Species-specific description: The polyneuropathy of juvenile Greyhounds shows clinical similarities to the genetically heterogeneous Charcot-Marie-Tooth disease in humans.

Molecular basis: After genotyping 7 affected Grehounds and 17 normal related Greyhounds with the 50K dog SNP chip, Drögemüller et al. (2010) used homozygosity mapping to identify the candidate 19.5 Mb region on chromosome CFA13. By sequencing the most likely candidate gene in this region, they identified the causative mutation as a 10 bp deletion in exon 15 of the NDRG1 gene (c.1080_1089del10).

Bruun et al. (2013) investigated the same disorder in Alaskan Malumutes and reported a novel mutation in the same gene: "The coding sequence of the NDRG1 gene derived from one healthy and one affected Alaskan Malamute revealed a non-synonymous G>T mutation in exon 4 in the affected dog that causes a Gly98Val amino acid substitution." The causative variant in the Alaskan Malamute is c.293G>T.

Prevalence: By genotyping archived samples, Jäderlund et al. (2017) showed that "historical and recent phenotypic polyneuropathy cases were carrying the same NDRG1-mutation [c.293G>T; p.Gly98Val]. The pedigree analysis showed that all affected Alaskan malamute cases with polyneuropathy could be traced back to one common ancestor of North American origin."

Breeds: Alaskan Malamute, Greyhound.

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.
