Abstract Scientific advances have allowed the development of multiplex gene‐panels to assess many genes simultaneously in women who have tested negative for BRCA1/2 . We examined correlates of interest in testing for genes that confer modest and moderate breast cancer risk and risk communication preferences for women from BRCA negative families. Female first‐degree relatives of breast cancer patients who tested negative for BRCA1/2 mutations ( N = 149) completed a survey assessing multiplex genetic testing interes…
