S-locus (piebald, spotted white)*

Characteristic and trait of inheritance

White spotting in dogs is mostly caused by variations of MITF. Depending on a short interspersed nucleotide element (SINE), the dog is spotted or not.
Del is the dominant allele and causes solid or single-coloured dogs (genotype del/del). Dogs that inherit SINE (genotype int/int) homozygous have white markings that either cover at least the ventral surface (mantle pattern) or most of the body (piebald or extreme white spotting). In most breeds, dogs heterozygous for the SINE-insertion (genotype del/int) are solid colored or have minimal white spots, e.g. on the toes. In some other breeds heterozygotes show white undersides, often with a white collar called pseudo-Irish.

Breed

All breed

Test duration

3-5 weeks after arrival of the sample in the lab

Material

The DNA test is performed out of EDTA blood or buccal swabs. Required swabs can be ordered free of charge. (Buccal swab order-form). If a swab is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.

Testing procedure

Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer.
Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.
