It is due to deficiency of enzyme tyrosinase which is responsible for the hydroxylation of L-tyrosine to 3, 4, dihydroxyphenylalanine (DOPA) and its subsequent oxidation to dopaquinone.
The tyrosinase, encoded by tyrosinase (TYR) gene, is known to be the rate-limiting enzyme affecting the production of melanin pigment (Sanchez-Ferrer et al., 1995), which oxidates tyrosine to dihydroxyphenylalanine (DOPA) (Lerner and Fitzpatrick, 1950) and determines which type of melanin (eumelanin or phaeomelanin) could be synthesized (Ito et al., 2000).

It is thought to be produced when tyrosine, an amino acid in the skin, is oxidized by the enzyme tyrosinase to form 3,4 dihydroxyphenylalanine (DOPA), which is further oxidized by UV light and the catalyst tyrosinase to form an indole derivative which polymerizes to melanin.
