Griscelli Syndrome Type 1

GS1

Case Presentation Eleven Years old Saudi boy, followed up at our clinic since the age of 2 months, for Partial Albinism since birth. [omicsonline.org]

Tezcan I, Sanal O, Ersoy F, Uckan D, Kiliç S, Metin A, Cetin M, Akin R, Oner C, Tuncer A (1999) Successful bone marrow transplantation in a case of Griscelli disease which presented in accelerated phase with neurological involvement. [link.springer.com]

Griscelli syndrome has to be distinguished from Chediak-Higashi syndrome and Elejalde disease, which can also present with silvery hair. [pigmentinternational.com]

Primary neurological presentation is rare. [casereports.in]

The melanosomes are present in the center of melanocytes but must be transported to the outer part of the cells and into other cells in order to provide the pigmentation. [mybiosource.com]

    The features of silvery hair, cerebellar atrophy, hypopigmented skin lesions, and absence of recurrent infections was suggestive of Elejalde Syndrome. Discussion ES is a rare syndrome, which was first described by Elejalde et al. [3]. [symbiosisonlinepublishing.com]

Sepsis workup and CSF study including cytospin for malignant cells were negative. LDH was mildly elevated and serum ferritin, fibrinogen levels, triglycerides were normal ruling out possibility of hemo-phagocytosis [Table 1]. [casereports.in]

Treatment - Griscelli syndrome type 1 Treatment is aimed at the cause, if one can be found. Supportive therapy includes an anti-inflammatory, an antihistamine, and rest. [checkorphan.org]

However the prognosis of GS3 is good where no special treatment needed [ 17, 18 ]. GS3 patients have no need for treatment and as seen in the present case the patient has attained 11 year of age and doing well with no deficit or medical illness. [omicsonline.org]

You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]

Since prognosis, treatment options, and genetic counseling markedly differ among different types, molecular characterization has utmost importance in GS. [link.springer.com]

Management and treatment Treatment for GS type 1 is only symptomatic. In GS type 2, the hemophagocytic syndrome is often fatal and the only cure is hematopoietic stem cell transplantation (HSCT). [orpha.net]

Prognosis - Griscelli syndrome type 1 Not supplied. Treatment - Griscelli syndrome type 1 Treatment is aimed at the cause, if one can be found. Supportive therapy includes an anti-inflammatory, an antihistamine, and rest. [checkorphan.org]

Since prognosis, treatment options, and genetic counseling markedly differ among different types, molecular characterization has utmost importance in GS [ 19 ]. [omicsonline.org]

Prognosis If not treated by HSCT, the prognosis for long-term survival in GS type 2 is relatively poor, with many patients not surviving the first decade. The prognosis of GS type 1 is good. [orpha.net]

Prognosis depends on the severity of neurologic manifestations. Type 2 GS patients have mutations in RAB27A and hemophagocytic syndrome, with abnormal T-cell and macrophage activation. This type has a grave prognosis if untreated. [jddonline.com]

Etiology Mutations in in RAB27A (15q), which codes for a small GTPase(hemophagocytic syndrome) Mutations in MYO5A, which codes for an actin-based molecular motor (neurological involvement) The RAB27A and MYO5A gene products interact with each other and [humpath.com]

Etiology GS type 1 is caused by a mutation in the myosin Va (MYO5A) gene located on chromosome 15q21 and likely corresponds to Elejalde disease. GS type 2 is caused by mutations in the RAB27A encoding gene. [orpha.net]

The genetic mutation affects the transportation of melanosomes thus trapping them in the center of the melanocytes preventing the normal pigmentation of the eyes, hair and skin. [mybiosource.com]

Management [ 4 ] Drug Allogenic bone marrow transplantation (BMT) from an HLA-matched sibling is the treatment of choice but does not prevent the neurological disorders. [patient.info]

As a result, these structures clump near the center of melanocytes, trapping melanin within these cells and preventing normal pigmentation of skin and hair. [ghr.nlm.nih.gov]
