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]

This assertion is certainly correct but surprisingly is presented as new and as an “alternative explanation.” [ncbi.nlm.nih.gov]

Finally, GS 3 presents as hypopigmentation in the hair and skin without another findings and is related to a mutation in the 2q37.3 chromossome4-7. [scielo.br]

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]

• Microcytosis

  The initial laboratory investigations showed anemia (Hb: 11.3, HCT: 34.4) and granulocyte count was lower than normal (n=2500), in peripheral blood smear microcytosis and anisocytosis was obvious. The ESR was about 5. [ncbi.nlm.nih.gov]

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]

The prognosis for GS type 2 is quite poor without a HSCT - the disease is usually fatal within 1-4 years following the onset of HLH. [immunodeficiencysearch.com]

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]

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

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]

Griscelli Syndrome: Background, Pathophysiology, Epidemiology Griscelli syndrome type 3characterized by hypomelanosis with no immunologic or neurologic manifestations, can be caused by mutation in the melanophilin MLPH; or MYO5A genes. [getpdffrommiara.website]

Pathophysiology Griscelli syndrome is caused grsicelli mutations in 1 of 3 genes. Large granules of melanin unevenly distributed in the hair shaft were observed. Griscelli syndrome – Wikipedia Clinical Synopsis Toggle Dropdown. [pdffilesofjennifer.online]

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]

HSCT is indicated for all patients with GS type 2 to prevent infections as well as HLH. This is the only curative therapy available for this disease. [immunodeficiencysearch.com]

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