Griscelli Syndrome Type 3: A Case Report from Kingdom of Saudi Arabia

Griscelli syndrome (GS) is a rare autosomal recessive disorder characterized by partial albinism. GSis a rare condition; its prevalence is unknown. Type 2 appears to be the most common of the three known types. The three different types of GS are caused by mutations in three different genes. Patients with GS type 1 have primary central nervous system dysfunction, resulting from mutations in the MYO5A gene. Type 2 patients commonly develop hemophagocytic. Lymphohistiocytosis, caused by mutations in the RAB27A gene, and type 3 have only partial albinism resulting from mutations in the MLPH. While hematopoietic stem cell transplantation is lifesaving in type 2, no specific therapy is required for types 1 and 3. Patients with GS types 1 and 3 are very rare. To date, 12 patients with similar presentation of GS-3 as our case have been reported. About 20 GS type 1 patients, including the patients described as Elejalde syndrome, have been reported. We report a 11 years old child with type 3 GS, referred to our clinic for partial albinism, healthy otherwise, having only pigmentary dilution; silvery gray hair, eye brows, and eyelashes. Though GS type1 and 2 have been reported in the literature; however reports on GS type 3 from Saudi Arabia are very scanty. In communities with high incidence of consanguinity possibility of GS should be kept in mind.
