OMIA 001455-9615 : Cone-rod dystrophy, Standard Wire-haired Dachshund in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 606966 , 606996

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2008

Cross-species summary: This disorder has been renamed in OMIA on the basis of the review by Miyadera et al. (2012)

Species-specific symbol: CRD^SWHD

Mapping: Wiik et al. (2008) conducted a GWAS on 13 affected and 13 control Standard Wire-Haired Dachshunds, each genotyped with the Affymetrix version 2 Dog SNP (yielding 49,663 informative SNPs for analysis). They reporte that "For the first time, we use genome-wide association-based Sibling Transmission Disequilibrium Test (sibTDT) analysis of only 13 discordant sib-pairs to identify a single significantly associated 6.5-Mb region (PrawTDT = 4.8 × 10−5, PgenomeTDT = 6 × 10−4) on canine chromosome 5, containing more than 70 genes".

Molecular basis: Sequencing of positional candidate genes in the CFA5 region (see Mapping section) by Wiik et al. (2008) "identified a 180-bp deletion in exon/intron 5 of NPHP4 (nephronophthisis 4, also known as nephroretinin)".

Palánová et al. (2014) "analyzed all varieties of Dachshunds from the Czech Republic and five other dog breeds and found that the deletion in the NPHP4 (in heterozygous state) is present not only in standard-, but also in miniature wire-haired Dachshunds, but not in other varieties of Dachshunds or in other breeds."

Breed: Standard wire-haired dachshund.

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.
