People inherit two copies of each gene—one from each parent—an evolutionary fail-safe to ensure survival even when one of them doesn't function. For cancer-suppressor genes like BRCA1 ...

Mutations in the BRCA1 gene that are either inherited (germline) or acquired (somatic) might not be key to the initiation of prostate cancer, as previously thought, suggests the first study of its ...

Kim Kardashian, sister Khloe and their mother Kris Jenner were spotted at a San Diego genetic clinic on Tuesday which tests for the BRCA1 mutation. Whether or not the famous family was testing ...

The BRCA1 gene is located on the long arm of chromosome 17, at position 17q21. The gene spans around 100 kilobases and codes for a protein containing 1863 amino acids. Mutations or alterations ...

Jen Culton learned she had the BRCA1 gene mutation after her older sister's breast-cancer diagnosis. She decided to have two of her daughters tested; one daughter also has the BRCA1 gene mutation.

Twins Roxana and Ana Lopez put off BRCA1 genetic testing after their mom died of breast cancer, until one of them received her own diagnosis Julie Mazziotta is the Senior Sports Editor at PEOPLE ...

When it was discovered by researchers in 1994, the BRCA1 gene was hailed as a landmark achievement not just in breast cancer prevention but in medicine in general. Its discovery led to the ...

Each gene provides instructions for how to make certain proteins. These molecules help your cells work the right way. Everyone has two copies of the BRCA1 and BRCA2 genes, or BReast CAncer gene 1 ...

The BRCA1 gene is a genetic sequence that is located on the long arm of chromosome 17 at the 17q21 position. The gene spans around 100 kilobases and codes for a protein containing 1863 amino acids.

Abnormalities (mutations) in two genes -- BRCA1 and BRCA2 - are the most common causes of hereditary breast cancer, accounting for about 20% to 25% of cases. Usually, BRCA genes help to prevent ...

Some risk factors for breast cancer — such as diet, exercise or hormone medications — are preventable. But others, like certain genetic mutations, can’t be changed. It’s already known that ...
