WebThe albino state Albinism is a congenital, inherited disorder of melanin pigment and can be found throughout the animal kingdom. It is due to a metabolic error whereby the enzyme tyrosinase is either absent or inactive (Witkop 1979 ). WebMutations in Tyr might result in non-functional Tyr protein and, consequently, loss of pigment production.
