Point coloration in cats originated in the [[Siamese cat|Siamese]] and closely related Asian breeds, and is found in many Western-developed modern breeds. It is a form of partial [[albinism]] resulting from a [[mutation]] that affects [[tyrosinase]], an enzyme involved with [[melanin]] production. The mutated enzyme is [[thermolabile]]; it fails to work at normal body temperatures, but becomes active in cooler areas of the skin.<ref>{{cite journal
