Neutrophil immunodeficiency syndrome is a rare genetic disorder that affects the immune system. It is characterized by a deficiency in the number and function of neutrophils, a type of white blood cell that plays a crucial role in the body's defense against bacterial and fungal infections.

Symptoms

The primary symptom of neutrophil immunodeficiency syndrome is an increased susceptibility to recurrent and severe bacterial infections and fungal infections. These infections often affect the skin, lungs, and other organs. Other symptoms may include fever, fatigue, and weight loss.

Causes

Neutrophil immunodeficiency syndrome is caused by mutations in the RAC2 gene. This gene provides instructions for making a protein that is involved in the regulation of neutrophils. Mutations in the RAC2 gene disrupt the normal function of neutrophils, leading to a reduced ability to fight off infections.

Diagnosis

Diagnosis of neutrophil immunodeficiency syndrome is based on clinical symptoms, a history of recurrent infections, and laboratory tests that show a deficiency in the number and function of neutrophils. Genetic testing can confirm the diagnosis by identifying mutations in the RAC2 gene.

Treatment

Treatment for neutrophil immunodeficiency syndrome is focused on managing symptoms and preventing infections. This may include antibiotics to treat bacterial infections and antifungal medications to treat fungal infections. In severe cases, a bone marrow transplant may be considered.
