Abstract:

Griscelli syndrome is a rare autosomal recessive disorder that results in pigmentary dilution of the skin and the hair (silver hair) with  the presence of large clumps of pigment in hair shafts, and an accumulation of melanosomes in melanocytes.Three variants of disease have been found based on  genetic mutations. MYO5A, RAB27A and MLPH are the genes mutated leading to Griscelli syndrome type 1,2 and  3 respectively. Griscelli syndrome type 2 is the most common and if untreated leads to most severe presentation. Internationally there are 150 cases have been reported.
