Chronic granulomatous disease, because it affects phagocytic function, increases susceptibility to soft tissue infections, particularly of the skin, lungs, lymph nodes, and liver. Selective IgA deficiency and deficient IgGS1U1B12S1U1B0 subclass antibodies can predispose people to infection, but those infections respond readily to antibiotic treatment.Ataxia-telangiectasia can cause skin and liver problems, but its primary manifestations are ataxia and telangiectasia.
