Chediak-Higashi syndrome is a rare disease of the immune and nervous systems that involves pale-colored hair, eyes, and skin.
Chediak-Higashi syndrome is passed down through families (inherited). It is an autosomal recessive disease. This means that both parents are carriers of a non-working copy of the gene, and each parent must pass their non-working gene to the child for them to show symptoms of the disease.
Defects have been found in the CHS1 (also called LYST) gene. The primary defect in this disease is found in certain substances normally present in skin cells and certain white blood cells.
Children with this condition may have:
Other symptoms may include:
The doctor will perform a physical exam. This may show signs of a swollen spleen or liver or jaundice.
Tests that may be done include:
There is no specific treatment for Chediak-Higashi syndrome. Bone marrow transplants appear to have been successful in several patients, especially when performed early in the disease.
Antibiotics are used to treat infections. Antiviral drugs such as acyclovir and chemotherapy drugs are often used in the accelerated phase of the disease. Surgery may be needed to drain abscesses in some cases.

Death often occurs in the first 10 years of life, from chronic infections or accelerated disease that results in lymphoma-like illness. However, some affected children have survived longer.
Call your health care provider if you have a family history of this disorder and you are planning to have children.
Call for an appointment with your health care provider if your child shows symptoms of Chediak-Higashi syndrome.
Genetic counseling is recommended before becoming pregnant if you have a family history of Chediak-Higashi.
