Cats with a van pattern carry a piebald gene, which is the same gene that causes the white color on cats with tuxedo (black with a white belly) or bicolor (a color plus white) patterns.
The coloration of the Turkish Van, which is considered by many to be the original breed to carry the gene, calls for a white, semi-longhaired cat with colored markings restricted primarily to the head and tail.
