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][2]
  • 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.[3]
