Breast cancer and importance of zygosity determination in triplet sisters

Henry T. Lynch, Patrice Watson, Theresa Conway, Jane Lynch, Jeff Boyd

Research output: Contribution to journalArticle


This study is the first to examine the genetic risk in a breast cancer-prone family wherein two of three triplet sisters and their mother manifested breast cancer. The unaffected triplet, the proband, was found to be monozygotic with her deceased sister through DNA testing of tumor blocks and dizygotic to her living affected sister. Genetic counseling implications are discussed.
