Study: A new method for determining whether genetic variants in BRCA1 increase cancer risk
Ever since BRCA1 was discovered, researchers have been trying to understand which of the thousands of possible DNA changes in this gene increase cancer risk and which are harmless changes. A new study in Nature reports how a cutting-edge technology called “genome editing” may be used to classify changes—known as variants of uncertain significance-in BRCA1 as harmful or harmless. Once validated, this same technology may be used to classify variants in other genes. (9/29/18)

Article: Cancer experience in families affects decision making
Women with inherited mutations in genes that increase breast and ovarian cancer risk have an additional challenge: coping with how those mutations impact their families and how a family member’s cancer experience can shape their own perception. In a recent U.S. News and World Report article, Elaine Howley explores how a woman's decisions about healthcare, cancer prevention and treatment are affected by experience with cancer in the family.

Study: Hormone therapy and breast cancer risk after ovary removal in women with a BRCA1 mutation
Does hormone therapy (HT) alter the risk of breast cancer for woman carrying a BRCA1 mutation who have never been diagnosed with cancer? In this study, researchers showed that among women with BRCA1 mutations, HT use did not increase breast cancer rates for 10 years after ovary removal. More women taking combined estrogen plus progesterone developed breast cancer compared to those taking estrogen only, though this difference was not statistically significant. (9/7/18)

Study: Study identifies genes associated with risk of triple-negative breast cancer
Panel testing can identify women who are at increased risk for breast cancer. However, those at risk for triple-negative breast cancer cannot easily be identified because other than BRCA1, genes that increase the risk for triple-negative breast cancer are unknown. A new study uses panel testing to identify which genes increase the risk for triple-negative breast cancer. (8/23/18)

Study: Evaluation of some direct-to-consumer genetic testing reveals inaccuracies and misinterpretations
A clinical genetic testing laboratory examined results from direct-to-consumer genetic testing ordered directly by patients. They found many instances of false positives—reported mutations that were not actually present—and in some cases, reports of variants that "increased risk," but were actually benign. This study emphasized the importance of involving genetics experts in the interpretation of genetic test results. (6/28/18)

Article: The right not to know when not knowing is dangerous
Healthcare providers are bound by the guiding principle of doing no harm. But how does this concept apply to their patients who have not consented to genetic testing or who do not want to know their results? In that case, is providing test results more harmful or not? Anna Clausen explores these issues in the context of breast cancer gene testing in her Global Health Now article “The Right Not to Know: When Ignorance is Bliss but Deadly.” (4/20/18)
