USP18 deficiency is a rare genetic disorder caused by a mutation in the USP18 gene. It is characterized by recurrent infections, inflammation, and autoimmune disorders. Symptoms can include recurrent infections, fever, fatigue, skin rashes, joint pain, and organ inflammation. Treatment typically involves immunosuppressive medications and supportive care.

The symptoms of USP18 deficiency vary from person to person, but may include recurrent infections, failure to thrive, poor growth, recurrent fever, enlarged lymph nodes, and skin rashes. Other symptoms may include anemia, thrombocytopenia, and neutropenia.

USP18 deficiency is a rare genetic disorder caused by mutations in the USP18 gene. These mutations can be inherited from a parent or can occur spontaneously. USP18 deficiency is caused by a lack of the enzyme ubiquitin-specific protease 18, which is responsible for regulating the immune system.

Currently, there is no specific treatment for USP18 deficiency. Treatment is focused on managing the symptoms and complications associated with the condition. This may include medications to reduce inflammation, physical therapy to improve mobility, and nutritional support to maintain a healthy weight. In some cases, surgery may be necessary to correct any physical deformities or joint problems.
