Genetics of Hodgkin's and non-Hodgkin's lymphoma: a review.

Host susceptibility factors have been documented in both HD and NHL wherein a subset of pedigrees provide evidence for an autosomal dominantly inherited factor. Families with both HD and NHL occurring in genetically informative patients provide evidence in support of a possible common pathogenetic pathway for these diseases, as does recent cytogenetic and molecular genetic evidence. AIDS as an unmasking factor for familial predisposition to lymphoma and other cancers may be a powerful tool for identifying lymphoma- and cancer-prone families, but to date has not been employed. In concert with ecogenetic research, it will be important that lymphoma-prone families be subjected to multidisciplined research involving experimental designs developed by geneticists and epidemiologists in concert with pathologists, immunologists, and molecular geneticists.
