Abstract
A 7-month-old Turkish boy presented with partial albinism and typical clinical features of an accelerated phase, suggesting the diagnosis of Griscelli syndrome. The diagnosis was confirmed by light microscopic evaluation of hair and a peripheral blood smear. Genetic analysis identified a mutation in the Rab27A gene. He was initiated immunosuppressive treatment but accelerated phase could not be ameliorated. He unfortunately died from multiorgan failure. The finding of partial albinism in children should alert clinicians to consider Griscelli syndrome since simple methods can confirm the diagnosis and early diagnosis is life-saving.

Abstract
Elejalde syndrome is a rare autosomal recessive condition, with only 10 reported cases through 2001. It is characterized by silvery hair, pigment abnormalities, and profound central nervous system dysfunction. The differential diagnosis includes Griscelli and Chediak-Higashi syndromes, which present with silvery hair, pigment abnormalities, central nervous system alterations, and severe immunologic dysfunction. We report a 6-year-old girl with Elejalde syndrome and review Elejalde, Griscelli, and Chediak-Higashi syndromes.

Abstract
An eight month old male infant presented with recurrent infections and partial albinism. Initially a possibility of Chediak Higashi syndrome (CHS) was considered, but a negative investigative work up prompted us to look for an alternate diagnosis. A literature search revealed that Griscelli syndrome (GS) has overlapping symptoms and signs. The findings in skin and hair biopsies in Griscelli syndrome are distinctive.

Abstract
White, identical twin boys aged 3 months were referred to our centre with persisting fever, mouth ulcers, hepatosplenomegaly, pancytopenia and failure to thrive. The parents were first cousins and there was a history of a sibling with similar manifestations who had died. The infants had silvery-grey hair and pigment clumps on the hair shafts, and skin biopsy showed accumulation of melanocytes on melanosomes. Bone marrow revealed hypercellularity and haemophagocytosis. HLH-94 chemotherapy (initial therapy with daily dexamethasone and etoposide, maintenance with dexamethasone pulses, etoposide and cyclosporin A) was started. Though partial haematological remission was achieved, one of the boys died on the 34th day following aspiration pneumonia. No pathogen could be identified. The second boy responded to therapy but had a haematological relapse and died 68 days after first being admitted. Genetic study revealed a 5 bp deletion in the RAB27A gene (510 del AAGCC in exon 5). Transient haematological remission can be achieved with chemotherapy but allogeneic bone marrow transplantation is the only curative therapy in Griscelli disease, as in other familial haemophagocytic syndromes. Identification of the mutation also provides an opportunity for prenatal diagnosis.

Abstract
We present an eleven-year-old female patient who was referred to us with silvery hair, hepatosplenomegaly, neutropenia-thrombocytopenia, hypogammaglobulinemia and degenerative white matter disease, with a family history of a female sibling dying at the age of five and two living male cousins, ages 10 and 11. She had been followed up for her cytopenia the last three years and had totally recovered from a hemiplegic episode before admission. The family was of Arabic origin, and a second-degree consanguinity was reported between the parents. Microscopic analysis of her hair shafts revealed irregularly distributed small and large clumps of melanin, and skin biopsy findings were consistent with partial albinism. Bone marrow aspiration and biopsy did not detect any evidence of hemophagocytosis. Genetic analysis identified a homozygous two-base-pair deletion (51 del CT leading to S18X) in the Rab27A gene of the patient. She suffered from febrile neutropenic episodes. Her persistent cytopenia could not be corrected with immunoglobulin, thrombocyte infusions, or a short course of growth factor treatment. Splenectomy was planned due to her progressive splenic enlargement. She was also considered for bone marrow transplantation. She unfortunately died from an intracranial hemorrhage. Her clinical presentation was remarkable, mostly resembling partial albinism immunodeficiency/Elejalde syndrome due to her older age and absence of hemophagocytosis, but with molecular findings confirming Griscelli syndrome.

Abstract
Griscelli syndrome (GS), a rare autosomal recessive disorder, is characterized by partial albinism, along with immunologic abnormalities or severe neurological impairment or both. Mutations in one of two different genes on chromosome 15q can cause the different subtypes of GS. Most patients with GS display the hemophagocytic syndrome and have mutations in RAB27A, which codes for a small GTPase. Two patients with neurological involvement have mutations in MYO5A, which codes for an actin-based molecular motor. The RAB27A and MYO5A gene products interact with each other and function in vesicle trafficking. We report the molecular basis of GS in a Muslim Arab kindred whose members have extremely variable neurological involvement, along with the hemophagocytic syndrome and immunologic abnormalities. The patients have normal MYO5A genes but exhibit a homozygous 67.5-kb deletion that eliminates RAB27A mRNA and immunocytofluorescence-detectable protein. We also describe the molecular organization of RAB27A and a multiplex polymerase chain reaction assay for the founder deletion in this kindred. Finally, we propose that all patients with GS have RAB27A mutations and immunologic abnormalities that sometimes result in secondary neurological involvement. The two patients described elsewhere who have MYO5A mutations and neurological complications but no immunologic defects may not have GS but instead may have Elejalde syndrome, a condition characterized by mild hypopigmentation and severe, primary neurological abnormalities.

Abstract
Griscelli disease is a rare autosomal recessive disorder characterized by diffuse pigmentary dilution and occurrence of acute phases of uncontrolled lymphocyte and macrophage activation, so-called "hemophagocytic syndrome" (HS) that leads to death. Recently, two closely linked genes located on human 15q21 region have been found to be responsible for the disease. We present clinical and laboratory findings of 13 unrelated patients with Griscelli disease as well as mutation analyses in an effort to define a genotype-phenotype correlation. Eight patients who showed RAB27A mutations presented with HS. In contrast, two patients who primarily presented with a neurological impairment in the absence of infection susceptibility or HS were found to have homozygous MYO5A mutations. No mutation in RAB27A could be detected in the other three patients. One of the latter developed HS at a rather late age, while the other two are free of HS at 12 and 15 years of age. Griscelli disease presents with a heterogeneous clinical picture that seems to reflect the involved gene defect. This genotype-phenotype correlation suggests that the natural course of the disease and outcome is dictated by the site and type of the genetic mutation.

Abstract
Griscelli syndrome (GS) is a rare inherited disease characterized by immunodeficiency and partial albinism. The microscopic findings of the skin and hair are highly suggestive of the disease. The GS locus colocalizes on chromosome 15q21 with the myosin-Va gene (MYO5a), and mutations have been identified in few patients. We describe a 2-month-old Hispanic girl with severe pancytopenia secondary to hemophagocytosis. Even though a mutation at the Griscelli locus had not been identified, her clinical features and outcome were typical of GS. The purpose of this article is to alert physicians to the association between GS and hemophagocytosis. We suggest that GS should be considered in infants with hemophagocytosis because the features of partial albinism can be subtle. The relevant literature is summarized.

Abstract
Chediak-Higashi syndrome (CHS) is a rare autosomal recessive disorder characterized by variable degrees of oculocutaneous albinism, easy bruisability, and bleeding as a result of deficient platelet dense bodies, and recurrent infections, with neutropenia, impaired chemotaxis and bactericidal activity, and abnormal NK cell function. Neurologic involvement is variable, but often includes peripheral neuropathy. Most patients also undergo an "accelerated phase," which is a nonmalignant lymphohistiocytic infiltration of multiple organs resembling lymphoma. Death often occurs in the first decade from infection, bleeding, or development of the accelerated phase. The hallmark of CHS is the presence of huge cytoplasmic granules in circulating granulocytes and many other cell types. These granules are peroxidase-positive and contain lysosomal enzymes, suggesting that they are giant lysosomes or, in the case of melanocytes, giant melanosomes. The underlying defect in CHS remains elusive, but the disorder can be considered a model for defects in vesicle formation, fusion, or trafficking. Because the beige mouse demonstrates many characteristics similar to those of human CHS patients, including dilution of coat color, recurrent infections, and the presence of giant granules, it is considered the animal homologue of CHS. The beige gene, Lyst, was mapped and sequenced in 1996, prompting identification of the human LYST gene on chromosome 1q42. Lyst and LYST show 86.5% sequence homology. LYST encodes a 429 kDa protein with a function that remains unknown, but the source of extensive speculation among students of cell biology.

Abstract
Hemophagocytic lymphohistiocytosis (HLH), also referred to as familial erythrophagocytic lymphohistiocytosis, is a rare disorder of infancy associated with proliferation of activated histiocytes and T cells, anemia, thrombocytopenia, and fevers. This disorder appears to be due to the uncontrolled activation of T cells producing IL-2, tumor necrosis factor-alpha, and interferon-gamma. Untreated, the disorder is universally fatal. Various deficits in immune function have been described during acute disease activity including impaired T cell function, impaired monocyte-mediated antibody-dependent cytotoxicity, impaired natural killer cell function, and impaired IL-1 production. We examined natural killer cell function in familial HLH patients to determine whether this finding was consistently associated with the disease. We also examined natural killer cell function in asymptomatic parents and siblings of patients. Impaired natural killer cell function was identified in all patients and in some family members, including obligate carrier parents. This implies that one potential genetic defect in HLH may result in depressed natural killer function, but that this may not be sufficient to reliably predict eventual progression to disease.

Abstract
Partial albinism with immunodeficiency (Griscelli syndrome) is an uncommon disorder characterized by pigmentary dilution and variable immunodeficiency. Features include a silvery-gray sheen to the hair, large clumped melanosomes in hair shafts, and prominent mature melanosomes in cutaneous melanocytes with sparse pigmentation of adjacent keratinocytes. Immunologic abnormalities most often include impaired natural killer cell activity, absent delayed-type hypersensitivity, and impaired responses to mitogens. Impaired helper T cell function and hypogammaglobulinemia have also been described. The syndrome can be differentiated from Chediak-Higashi syndrome by pathognomonic light and electron microscopic features in skin and hair, and absence of consistent granulocyte abnormalities, but similarly carries a poor prognosis without bone marrow transplantation. We describe a patient with Griscelli syndrome who presented with hepatosplenomegaly, hepatitis, pancytopenia, and silvery hair in the newborn period.

Abstract
We report a male caucasian German pediatric patient of no Arab or Mediterranean ancestry with virus associated CNS lesions in Griscelli's syndrome (GS; McKusick No. 214450). The boy presented with recurrent infections, and meningitis with subsequent progressive signs of increased intracranial pressure leading to death at 32 weeks of age. At autopsy, various sites of the CNS revealed necroses in gray and white matter. CNS histology revealed numerous and massive predominantly perivascular CD8 positive lymphohistiocytic infiltrates. These findings were associated strictly with the presence of human herpesvirus-6 (HHV-6) genome or the HHV-6 specific late antigen H-AR 3, found in neurons, oligodendrocytes, and astrocytes. The search for HHV-6 replication dependent antigen, HHV-7 DNA, CMV, adenovirus, Coxsackie B1, B2, and B4-antigens, and mycobacteria was not successful. Detection of viruses was attempted using immunohistochemistry, in situ hybridization or nested polymerase chain reaction, respectively. Lymphocyte typing was carried out immunohistochemically. In GS, virus induced CNS damage does not seem to require necessarily active virus replication. It may also appear as a consequence of an immune reaction triggered by antigen expression.
