IL2RG gene

The IL2RG gene provides instructions for making a protein called the common gamma chain, which is essential for the immune system to function properly. This protein is part of several receptors on immune cells that help them communicate and fight infections. If the IL2RG gene is faulty or missing, it can lead to severe combined immunodeficiency (SCID), a condition where the immune system is severely compromised, making individuals highly vulnerable to infections. The gene's proper function is crucial for the development and activity of various immune cells that protect the body.
