What is Chediak-Higashi?
Chediak-Higashi syndrome (CHS; MIM #214500) is a rare, autosomal-recessive disorder characterized by recurrent bacterial infections including pyogenic infections, oculocutaneous albinism that is present to a variable extent, progressive neurologic abnormalities, mild coagulation defects, and a high risk of developing …
What is the defect in Chediak-Higashi syndrome?
Griscelli syndrome, also known as Chediak-Higashi-like syndrome, is a rare inherited disorder characterized by partial albinism and abnormalities of platelets and white blood cells.
What enzyme causes Chediak Higashi?
Chediak-Higashi syndrome is caused by mutations in the LYST gene. This gene provides instructions for making a protein known as the lysosomal trafficking regulator.
Is Chediak Higashi fatal?
Chédiak–Higashi syndrome is usually fatal at a young age, although some patients can survive until age 20 or 30 years. These survivors are usually confined to a wheelchair by their neurological symptoms.
What enzyme causes Chediak-Higashi?
What are the symptoms of Chediak-Higashi syndrome?

- frequent infections in the lungs, skin, and mucous membranes.
What is Chediak-Higashi syndrome symptoms?
How does Chediak-Higashi syndrome affect the immune system?
This disease damages immune system cells, leaving them less able to fight off invaders such as viruses and bacteria. As a result, most people with Chediak-Higashi syndrome have repeated and persistent infections starting in infancy or early childhood. These infections tend to be very serious or life-threatening.
Is the Chediak-Higashi syndrome communicable?
Both parents of a child with this type of genetic disorder carry a copy of the defective gene, but they usually don’t show signs of the condition. If only one parent passes on the defective gene, the child won’t have the syndrome but may be a carrier. That means they could pass the gene on to their children.
What is Chediak Higashi syndrome?
Chediak Higashi syndrome (CHS) is an autosomal recessive disorder that is characterized by easy bruising, oculocutaneous albinism and recurrent pyogenic infections. The defect is caused by a mutation in the lysosomal trafficking regulator protein that leads to decreased phagocytosis and predisposition to recurrent bacterial infection.
