BRCA2 and acinar cell carcinoma: Furukawa and coworkers have performed the exome sequencing of 11 acinar cell carcinomas and identified recurrent mutations of BRCA2 and FAT genes: somatic or germline premature BRCA2 mutations were observed in three of seven tumors, while FAT1, FAT3 and FAT4 somatic or germline mutations were observed in four of seven tumors [42].
