We now report identification of a novel p53 mutation affecting the splice acceptor site of exon 6 in the germline DNA of a family with hereditary breast-ovarian cancer.
A collaborative survey of 80 mutations in the BRCA1 breast and ovarian cancer susceptibility gene. Implications for presymptomatic testing and screening.
To investigate the putative role of BRCA1, a gene involved in hereditary breast and ovarian cancer, in sporadic ovarian tumors among Japanese women, we examined 76 unselected primary ovarian cancers for mutations in the coding region of BRCA1 using the single-strand conformation polymorphism technique.
Examples include the RB1 gene for retinoblastoma; the WT1 gene for Wilms' tumor; germline p53 mutations in families with the Li-Fraumeni syndrome; the NF1 and NF2 genes for neuroblastomatosis, types 1 and 2; the VHL gene for renal cancer and other tumors associated with Von Hippel-Lindau disease; the APC gene for adenomatous polyposis coli; the BRCA1 gene for hereditary breast and ovarian cancer; and the mismatch repair genes for colon and other common cancers.
We describe a 43-year-old woman from a hereditary breast-ovarian cancer (HBOC) family which showed linkage to BRCA1 and who was at inordinately high risk for cancer but who was denied insurance coverage for prophylactic oophorectomy, despite strong recommendations by her gynecologist and a cancer geneticist-medical oncologist.
Genetic epidemiological evidence suggests that mutations in BRCA1 may be responsible for approximately one half of early onset familial breast cancer and the majority of familial breast/ovarian cancer.
