Camarillo White - W4*

Characteristic and trait of inheritance

Camarillo White W4* Camarillo White Horses are the result of a KIT gene mutation called W4. A Southern California rancher named Adolfo Camarillo purchased Sultan, a white stallion born around 1912, and bred him to Morgan Horse mares to create white horses that became famous performers in the Pasadena Tournament of Roses parade and other local events. The Camarillo family kept the white horses until 1987 when they were dispersed at a public auction. In 1992 the Camarillo White Horse Association was formed to preserve white horses descended from Sultan. The test is specific for the W4 mutation in the KIT gene that produces the dominant white phenotype of Camarillo White Horses. Homozygous CW/CW horses have not been observed. The W4 mutation is likely to be lethal in utero.


all breeds

Test duration

3-4 weeks after arrival of the sample in the lab


The DNA test is performed out of EDTA blood or or 20-30 hair roots from mane or tail. Test kits can be ordered free of charge. (order-form). If hair 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.
