MLPH and Griscelli disease type 3: Griscelli syndrome type 3 (GS3) represents a restricted expression of the disease, caused by a mutation in the melanophilin gene located at 2q37, which leads to hypopigmentation and the presence of gray hair observed in all GS subtypes.[5,6] GS3 has the best prognosis among the 3 types, as it has no impact on either the nervous or immune systems and requires no form of therapy.[7]
