Mutations in the BRCA1 and BRCA2 tumor suppressor genes are associated with an increased risk for breast and ovarian cancers as well as other types of malignancies. The observation of a germline BRCA1 mutation in an index case with a lymphoid neoplasm in the setting of a family history of breast cancer prompted us to explore the role of BRCA germline mutations as lymphoma susceptibility alleles. A panel of 286 DNA samples from Jewish lymphoma patients was analyzed for the three most frequent BRCA1 and BRCA2 germline mutations in those of Ashkenazi Jewish heritage, and compared to a cohort of 5010 DNA samples from healthy controls. Of the 286 cases, 2 patients carried a germline BRCA mutation; Both were diagnosed at an early age with an intermediate grade non-Hodgkin's lymphoma. This data indicate that germline BRCA mutations are not associated with an increased risk for lymphoid malignancies.
