Cancer predisposition in some families is known to be the result of germ-line mutations. The most noteworthy hereditary gynecologic cancer syndromes include hereditary breast-ovarian cancer (HBOC) syndrome, wherein BRCA1 and BRCA2 germ-line mutations have been identified, and hereditary nonpolyposis colorectal cancer (HNPCC) of the Lynch syndrome II variant, wherein hMSH2, hMLH1, hPMS2, hMSH3, ...

background: hereditary non-polyposis colorectal cancer (hnpcc) is a common hereditary cancer predisposing syndrome has molecular and clinicopathological features still have remained ambiguous within iranian populations. we discuss in this article some molecular and clinicopathological features of the condition. methods: the study was a descriptive retrospective and designed on 1659 colorectal c...
Known gene mutations account for approximately 50% of the hereditary risk for breast cancer. Moderate and low penetrance variants, discovered by genomic approaches, account for an as-yet-unknown proportion of the remaining heritability. A truncating mutation c.325C>T:p.Arg109* (R109X) in the ATP-dependent helicase ERCC3 was observed recurrently among exomes sequenced in BRCA wild-type, breast c...
Testing for cancer susceptibility gene, in particular mutations in the BRCA1 gene in association with hereditary breast/ovarian cancer has been extensively studied. We investigated germline mutations in the BRCA1 gene from two Korean hereditary breast/ovarian cancer families using direct DNA sequencing. Blood samples of the thirteen family members were studied. We found three missense mutations...
Mitochondrial genome and functional alterations are related to various diseases including cancer. In all cases, the role of these organelles is associated with defects in oxidative energy metabolism and control of tumor-induced oxidative stress. The present study examines the involvement of mitochondrial DNA in cancer and in particular in breast cancer. Furthermore, since mitochondrial DNA is m...
BACKGROUND It is estimated that there will be more than 244,000 new prostate cancer cases diagnosed and that more than 40,000 men will die of this disease during 1995. Evidence exists for a hereditary predisposition to prostate cancer, but the proportion of cases attributable to the inheritance of a specific gene or genes is not large. Some hereditary cancer syndromes involve more than one tumo...
Women with a family history of breast cancer have an increased risk of developing the disease. Women identified as "high risk" for developing breast cancer have been shown to exhibit increased levels of psychological distress and anxiety related to breast cancer. Oncology nurses can address this barrier and others, such as altered risk perception and lack of physician recommendation for screeni...
Breast cancer is the most common malignancy in women around the world. About one in 12 women in the West develop breast cancer at some point in life. It is estimated that 5%-10% of all breast cancer cases in women are linked to hereditary susceptibility due to mutations in autosomal dominant genes. The two key players associated with high breast cancer risk are mutations in BRCA 1 and BRCA 2. A...
