Summaries for Griscelli Syndrome, Type 1

OMIM : 57 Griscelli syndrome type 1 (GS1) represents hypomelanosis with a primary neurologic deficit and without immunologic impairment or manifestations of hemophagocytic syndrome (Menasche et al., 2002). Griscelli syndrome with immune impairment, or Griscelli syndrome type 2 (607624), is caused by mutation in the RAB27A gene (603868). Griscelli syndrome type 3 (609227), characterized by hypomelanosis with no immunologic or neurologic manifestations, can be caused by mutation in the melanophilin (MLPH; 606526) or MYO5A genes. Griscelli syndrome is a rare autosomal recessive disorder that results in pigmentary dilution of the skin and hair, the presence of large clumps of pigment in hair shafts, and an accumulation of melanosomes in melanocytes. While most patients also develop hemophagocytic syndrome, leading to death in the absence of bone marrow transplantation (Menasche et al., 2000), some show severe neurologic impairment early in life without apparent immune abnormalities. Bahadoran et al. (2003) characterized GS1 as comprising hypomelanosis and severe central nervous system dysfunction, corresponding to the 'dilute' phenotype in the mouse, and GS2 as comprising hypomelanosis and lymphohistiocytotic hemophagocytosis, corresponding to the 'ashen' phenotype in mouse. Anikster et al. (2002), Menasche et al. (2002), Huizing et al. (2002), and 3,2:Bahadoran et al. (2003, 2003) suggested that Elejalde syndrome (256710) in some patients and GS1 represent the same entity. (214450)

MalaCards based summary : Griscelli Syndrome, Type 1, also known as griscelli syndrome type 1, is related to griscelli syndrome and griscelli syndrome, type 2, and has symptoms including seizures An important gene associated with Griscelli Syndrome, Type 1 is MYO5A (Myosin VA), and among its related pathways/superpathways are Epstein-Barr virus infection and Small cell lung cancer. Affiliated tissues include skin, bone and bone marrow, and related phenotypes are nystagmus and diplopia

Disease Ontology : 12 A Griscelli syndrome characterized by silvery gray sheen of the hair, hypopigmentation of the skin and neurological impairment without immunodeficiency that has material basis in mutations in the MYO5A gene on chromosome 15q21.2.

UniProtKB/Swiss-Prot : 75 Griscelli syndrome 1: Rare autosomal recessive disorder that results in pigmentary dilution of the skin and hair, the presence of large clumps of pigment in hair shafts, silvery-gray hair and accumulation of melanosomes in melanocytes. GS1 patients show developmental delay, hypotonia and mental retardation, without apparent immune abnormalities.
