These cats have a mutation that means the enzyme responsible for melanin (pigment) production denatures (lose its shape and consequently its function) at the normal core body temperature. Thus pigment is only produced in the fur on the cooler areas of the cat’s body - its tail, its extremities, its ears, and its nose, because of the cool air passing through the nasal passages.
