OMIA 001140-9615 : Cleft lip with or without cleft palate in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 119530 , 600625 , 608864 , 602966 , 600757 , 608371 , 608874 , 608864 , 613705 , 610361

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2015

Species-specific symbol: CL/P

Mapping: From a GWAS on 7 affecteds and 112 control Nova Scotia Duck Tolling retrievers, each genotyped with the Illumina CanineHD BeadChip (yielding 110,021 informative SNPs), Wolf et al. (2015) mapped this disorder to a 2.88Mb region on chromosome CFA27. Subsequent homozygosity mapping narrowed this to a 1.44Mb region, namely CFA27: 9.29–10.73 Mb

Molecular basis: Frameshift deletion: c.1360_1361delAA; p.Lys453Ilefs*3 (CanFam 3.1 boxer reference genome) "resulting in premature truncation of 1461 amino acids from the 1916 amino acid protein" (Wolf et al., 2015)

Breed: Nova Scotia Duck Tolling retriever.

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.
