Chediak–Higashi syndrome

Overview

Chediak-Higashi syndrome is a rare genetic disorder that affects the immune system and the body's ability to fight infections. People with this syndrome have abnormal white blood cells that are not able to properly destroy bacteria and viruses. This makes them more susceptible to recurrent infections, which can be severe and life-threatening. In addition to immune system problems, individuals with Chediak-Higashi syndrome may also have certain physical characteristics such as silver-gray hair and eye abnormalities.

Furthermore, the syndrome affects the body's ability to produce melanosomes, which are responsible for giving color to the skin, hair, and eyes. This results in the characteristic silver-gray hair and can also cause problems with vision. In addition to these physical characteristics, individuals with Chediak-Higashi syndrome may also experience neurological symptoms, such as intellectual disability and delayed development. Treatment for Chediak-Higashi syndrome focuses on managing infections and symptoms, as there is currently no cure for the condition.
