Recent studies suggest that mutations in DNA repair genes are associated with PARP beyond the synthetic lethal targeting of BRCA1/BRCA2 mutated tumors, 

Although the NCCN does not have melanoma screening guidelines for men with a BRCA2 gene mutation, it does recommend they consider yearly full-body skin exams to check for signs of melanoma and limit sun exposure [ 155 ]. Men who have a BRCA2 gene mutation, and to a lesser degree men who have a BRCA1 mutation, also have an increased risk of breast cancer [1]. Risk of other types of cancer.

BRCA2 gene mutations likely reduce the BRCA2 protein's ability to repair DNA, allowing potentially damaging mutations to persist in various other genes. The accumulation of damaging mutations can lead to the out-of-control cell growth and division that can result in development of a tumor.
