Partial albinism with immunodeficiency: A 13 year old girl presented with progressive ataxia, intentional tremors and slurring of speech for two months.

Rab27b is up-regulated in grisceoli Griscelli syndrome type II melanocytes and linked to the actin cytoskeleton via exon F-Myosin Va transcripts. Myosin-Va transports the endoplasmic reticulum into the dendritic spines of Purkinje neurons. Braz J Med Biol Res. Premature birth, griscleli distress, intracerebral hemorrhage, and silvery-gray hair: Chest x-ray dw normal. An allelic variant of Griscelli disease: Ophthalmic examination revealed snow drop appearance, perivascular cuffing [Fig.

Bone Marrow Transplant ; This can also result in the eye problem with decreased pigmentation of the iris. Immune impairment was not found. Finally, GS 3 presents as hypopigmentation in the hair and skin without another findings and griscellli related to a mutation in the 2q Instead, Lambert et al posited that the neurologic abnormalities may be linked to impaired function of a molecule playing a common role in melanocytic and neuronal organelle function.

Griscelli syndrome type 1 Elejalde syndrome. SA and VN were involved in clinical care of the patient. Thus, one way of classifying Griscelli syndrome is with other diseases that are associated with HLH, such as Chediak-Higashi syndrome.

CASE A 4-month-old male Brazilian infant, second child of consanguineous parents, with a healthy 6-year-old brother, was brought with complaints of recurrent chest infections. Griscelli disease with cerebral involvement. GS 2 represents patients with silvery gray hair, immunologic abnormalities and re neurologic defects and is related to RAB27A gene.

GS2 caused by mutations in RAB27A is characterized by hypopigmentation associated with an immune griwcelli, leading to episodes of life-threatening uncontrolled T-lymphocyte and macrophage activation that are the hallmark of hemophagocytic lymphohistiocytosis HLH [ 8 ].

Griscelli syndrome type-2 GS2 is characterized by cutaneous hypopigmentation, immunodeficiency, and hemo-phagocytic lympho-histiocytosis. Mutations in either Rab27a or Munc prevented the formation of this complex and abolished secretion. CC HPO:
