In addition to their distinctive coats, Appaloosas are also known for their hardy constitution and gentle disposition. These are mottled skin pigment on the face and/or genitals, hooves striped with narrow vertical bands and white sclera of the eye. Decreased expression of TRPM1 in the eye and the skin may alter both cell signaling and melanocyte function (another example of a gene showing pleiotropy). To date, there are three versions (alleles) of this gene that have been identified at the molecular level: E, e, and ea. In very minimal form, the horse may only show what are known as characteristics (sclera, mottled skin, and striped hooves on non-white legs) and even these can, at times, be so minimal as to escape notice.
