The chromosomal location of BRCA1 was discovered by Mary-Claire King's team at UC Berkeley in 1990. [21] After an international race to refine the precise location of BRCA1, [22] the gene was cloned in 1994 by scientists at University of Utah, National Institute of Environmental Health Sciences (NIEHS) and Myriad Genetics.
A negative test result, if a specific mutation is known to be present in the family, shows that the person does not have a BRCA-related predisposition for cancer, although it does not guarantee that the person will not develop a non-hereditary case of cancer. By itself, a negative test result does not mean that the patient has no hereditary ...

BRCA1-associated RING domain protein 1 is a protein that in humans is encoded by the BARD1 gene. [5] [6] [7] The human BARD1 protein is 777 amino acids long and contains a RING finger domain (residues 46-90), four ankyrin repeats (residues 420-555), and a tandem BRCT domain (residues 568-777).
However, many people remain healthy with such a loss, because there still is one functional gene left on the other chromosome of the chromosome pair. The remaining copy of the tumor suppressor gene can be inactivated by a point mutation or via other mechanisms, resulting in a loss of heterozygosity event, and leaving no tumor suppressor gene to ...
At the finish of this study, King's team was still unsure of the reason for such high levels of Triple-negative breast cancer, since many of the people diagnosed were not showing mutations in the BRCA1 gene. Her study supported the idea that genomic sequencing could be useful as a tool to help detect gene mutations early and be proactive in ...
