X-linked immunodeficiency

X-linked immunodeficiency is a genetic disorder where a gene on the X chromosome affects the immune system's ability to function properly. Since males have only one X chromosome, a mutation in this gene often leads to a weakened immune response, making it harder to fight infections. Females have two X chromosomes, so the healthy one can usually compensate. This condition can cause recurrent infections and increased vulnerability to illnesses. It’s inherited, meaning it runs in families, and affected individuals often require medical management to help boost their immune defenses.
