A coat variant associated with 'furnishings' (moustache and eyebrows) and facial wire hair in the dog, caused by a 167 bp insertion in the 3'UTR region of the RSPO2 gene. It is not a disease, but a morphological trait with variable expression. The test reports the genotype for the variant.

Described in the Dachshund (Cadieu et al. 2009) and in the Portuguese Water Dog (Parker et al. 2010). There are no reliable population frequencies by breed; mentions of other specific breeds require an additional source.

- Presence of moustache and eyebrows (furnishings)\n- Long facial hair/eyebrows; association with hard coat\n- Variable phenotypic expression between individuals and breeds\n- Does not cause disease

Cadieu et al. (2009), using GWAS, localized the furnishings signal to chromosome 13 and associated the trait with a 167 bp insertion in the 3'UTR of RSPO2. Parker et al. (2010) described the same insertion associated with the 'improper coat' coat in the Portuguese Water Dog.

- Use the test as a coat selection tool, not as a disease screening\n- Interpret the phenotype together with other coat loci (FGF5, KRT71)\n- Do not use medical language of 'affected/carrier' for this trait\n- Communicate that it is a morphological trait with variable expression

Do not confuse with dermatological pathology. The absence of furnishings ('improper coat') is associated with the variant in some breeds such as the Portuguese Water Dog. The final coat expression is polygenic.
