OMIA 001279-9615 : Hypotrichosis, recessive in Canis lupus familiaris
Hytönen and Lohi (2019) reported "a 1-bp insertion in exon 2 of SGK3 . . . [resulting] . . . in a predicted frameshift and very early truncation (49/490 amino acids) of the SGK3 protein." as a likely causal variant in Scottish Deerhounds.Prevalence: Hytönen and Lohi (2019) "genotyped the SGK3:c.137_138insT variant . . . in a cohort of Scottish Deerhounds (n = 66) containing two affected dogs, two unaffected dogs, which had produced affected progeny, and 62 other unaffected dogs from our biobank. Both affected dogs were homozygous for the variant and the two obligate carriers were heterozygous, while the rest of the dogs were either heterozygous (n = 6) or homozygous for the wild-type allele (n = 56). These results demonstrate a full segregation of the variant with the disease and indicate a 12% carrier frequency in the studied cohort. We screened the variant also in a related breed, Irish Wolfhound (n = 91), but did not find any carriers, suggesting a breed-specific variant in SD population." Breeds: American Hairless Terrier, Scottish Deerhound. Associated gene:

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.
