Bap1-Related Tumor Predisposition Syndrome, also known as tumor susceptibility linked to germline bap1 mutations, is related to bap1 tumor predisposition syndrome and tumor predisposition syndrome 1. An important gene associated with Bap1-Related Tumor Predisposition Syndrome is BAP1 (BRCA1 Associated Protein 1), and among its related pathways/superpathways are Homology Directed Repair and Homologous DNA Pairing and Strand Exchange. Affiliated tissues include skin and breast, and related phenotypes are Synthetic lethal with MLN4924 (a NAE inhibitor) and Decreased homologous recombination repair frequency
