Albinism or congenital nystagmusGene: MLPH
Limited evidence for an association with hypopigmentation. Comments from OMIM: Griscelli syndrome is a rare autosomal recessive disorder that results in pigmentary dilution of the skin and the hair (silver hair), the presence of large clumps of pigment in hair shafts, and an accumulation of melanosomes in melanocytes. OMIM describes 2 patients with hypopigmentation without any immunologicic or neurologic manifestations; they were reported by Sanal et al. 2002 (PMID 12148598). Menasche et al. 2003 (PMID 12897212) identified a homozygous mutation in the MLPH gene in one of these patients and a homozygous deletion of the F-exon of the MYO5A gene. Comments from HGMDpro: Only 7 variants in total; 4 of these have Griscelli syndrome as the reported phenotype (2 missense variants, one nonsense and one frameshift variant). The misense variant reported by Menasche et al 2003 is present.
