[7] Immunodeficiency with hypopigmentation or albinism: Chédiak–Higashi syndrome, Griscelli syndrome type 2; Familial hemophagocytic lymphohistiocytosis: perforin deficiency, UNC13D deficiency, syntaxin 11 deficiency
Humoral immune deficiency (including B cell deficiency or dysfunction), with signs or symptoms depending on the cause, but generally include signs of hypogammaglobulinemia (decrease of one or more types of antibodies) with presentations including repeated mild respiratory infections, and/or agammaglobulinemia (lack of all or most antibody production) which results in frequent severe infections ...

Congenital disorders of glycosylation are sometimes known as CDG syndromes.
Infusions can be administered in three different forms: intravenously (IVIg), [26] subcutaneously (SCIg), and intramuscularly (IMIg).
