Abstract
A three to sevenfold increased risk of Hodgkin's disease has been noted in families of patients. We report the first family in which all four of a four member sibship had Hodgkin's disease. In these four sibling cases, we were able to explore markers of infectious etiologic factors by measuring antibodies to Epstein Barr virus (EBV) and human T-cell lymphotropic virus (HTLV), and possible genetic risk factors by human leukocyte antigen (HLA) typing and chromosome analysis. All three men were diagnosed within six months of their 30th birthday. HLA typing revealed that all four siblings share the DR5 antigen, and two siblings share HLA-B27. Chromosome analysis on peripheral lymphocytes revealed no abnormalities. A detailed, structured interview failed to elicit evidence of unusual exposures. The EBV antibody titers are probably within the normal range and none of the family had antibodies to HTLV-III. Observations on this family suggest that genetic factors play a greater role than environmental factors in the etiology of familial Hodgkin's disease.
