OMIA:001787-9615 : Squamous cell carcinoma of the digit in Canis lupus familiaris (dog) |
Categories: Neoplasm , Limbs / fins / digit / tail phene
Links to possible relevant human trait(s) and/or gene(s) in OMIM: 184745 (gene)
Mendelian trait/disorder: no
Mode of inheritance: Multifactorial
Disease-related: yes
Key variant known: yes
Year key variant first reported: 2013
Species-specific symbol: SCCD
Mapping: A GWAS with the Affymetrix v2 Canine SNP Chip conducted by Karyadi et al. (2013) on 31 affected (dark-coloured) Standard Poodles and 34 unrelated black Standard Poodles, followed by fine-mapping, highlighted a 28.3kb region on chromosome CFA15, in which KITLG resides.
Molecular basis: Karyadi et al. (2013) identified a copy number variant (CNV) of KITLG that is very strongly associated with SCCD in (dark-coloured) Standard Poodles. Interestingly, light-coloured Standard Poodles have the same CNV at the same frequency, but are not affected, which suggests an interaction between KITLG and a coat-colour gene (Karyadi et al., 2013). A GWAS with the Illumina CanineHD BeadChip on 24 dark-coloured and 24 light-coloured Standard Poodles implicated variation at the coat-colour gene MC1R as the only difference between the two types of Standard Poodles. Aupperle-Lellbach (2023) investigated the KITLG CNV in giant (GS), standard (SS), and miniature (MS) Schnauzers and compared KITLG CNV between black GS with and without digital squamous cell carcinoma (dSCC): " Blood samples from black GS (22 with and 17 without dSCC), black SS (18 with and 4 without dSSC; 5 unknown), and 50 MS (unknown dSSC status and coat colour) were analysed by digital droplet PCR. ... most dogs had a copy number (CN) value > 4 (range 2.5-7.6) with no significant differences between GS, SS, and MS, and ... the CN value in black GS with dSCC was significantly higher than in those without dSCC (p = 0.02)."
Clinical features: As summarised by Karyadi et al. (2013), SCCD is a "locally aggressive cancer that causes lytic bone lesions, sometimes with multiple toe recurrence".
Prevalence: As mentioned above, only dark-coloured Standard Poodles are susceptible; light-coloured dogs of the same breed are rarely affected.

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.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
