title: A family study of IgG subclasses in sickle cell anemia.
abstract: Three siblings with sickle cell anemia were studied immunologically and hematologically. Their patterns of Protein A-Sepharose chromatography distribution showed considerable heterogeneity, particularly with respect to the IgG2 and IgG3 subclasses, even though their hematological make up was similar. An attempt was made to correlate their IgG2: IgG1 subclass ratios with their clinical history of recurrent bacterial infections, as well as a possible compensatory IgG3 heterogeneity.
