Chediak Higashi Syndrome
- Chediak Higashi syndrome is caused by homozygous or compound heterogenous autosomal recessive mutation in the lysosomal trafficking gene (LYST:606897) on chromosome 1q42.[1]
- It is characterized by photophobia, nystagmus, partial albinism, neutropenia, abnormal susceptibility to infections and malignant lymphoma, large eosinophilic peroxidase positive inclusion bosides in myeloblasts and promyelocytes of bone marrow.[2]
- The most effective treatment is hematopoeitic stem cell transplantation.[3]

Griscelli Syndrome type 2
- Griscelli syndrome type 2 is a rare autosomal recessive disease caused by mutation in the RAB27A gene. [4]
- It is characterized by partial albinism, immunodeficiency, organomegaly and accelerated phases which includes hemophagocytosis, pancytopenia and neurological deterioration.[5]
- The only curative treatment is hematopoeitic stem cell transplantation.[6]
