Abstract

Purpose: Jamaica is an island nation with one of the highest breast cancer incidence rates in the Caribbean (40/100,000 per year). The contribution of cancer susceptibility gene mutations to the burden of breast cancer in Jamaica has not yet been explored. We sought to determine the prevalence of germline mutations in BRCA1, BRCA2, and PALB2 in 179 unselected Jamaican women with breast cancer. Methods: We sequenced the entire coding regions of BRCA1, BRCA2, and PALB2 for all the study subjects. Results: Overall, 8 of 179 patients (4.5%) had a mutation in one of the three genes: one in BRCA1, two in BRCA2, and five in PALB2. Conclusions: These data suggest that in addition to BRCA1 and BRCA2, PALB2 should be included in genetic testing for breast cancer patients in Jamaica.
