BreastTrue® High Risk Panel Genetic Testing for High Risk Incidences of Breast Cancer Request a BreastTrue® Report What is BreastTrue® high risk panel? BreastTrue® High Risk Panel is a next-generation sequencing test that detects mutations in eight high-risk breast cancer susceptibility genes, including BRCA1, BRCA2 and PALB2. In addition, the test includes deletion/duplication analysis of Heterozygous germline mutations in either BRCA1 or BRCA2 that impair their normal function confer significantly elevated risks of breast, ovarian, and other cancers [].

With the analytical sensitivity and specificity of Differences in the mutation spectrum across ethnicities suggest the importance of identifying genes in addition to common high penetrant genes to estimate the associated breast cancer risk in China.

Inherited mutations in these genes are associated with the development of cancer in multiple organs including the breast and ovary. Mutations of BRCA1/2 genes greatly increase lifetime risk to develop breast and ovarian cancer and these Inheritance of one defective copy of either of the two breast-cancer-susceptibility genes, BRCA1 and BRCA2, predisposes individuals to breast, ovarian and other cancers. Both genes encode very large protein products; these bear little resemblance to one another or to other known proteins, and their precise biological functions remain uncertain. Case report: A 65-year-old woman diagnosed with HBOC harboring BRCA2 mutations was found to have multiple tumors in the stomach and small intestine by abdominal screening. All tumors were resected, and KIT gene mutations (p.Trp557Leu and p.Lys558Glu) in exon 11 were detected in all tumors and peripheral blood leukocytes. PubMed GeneCards Summary for BRCA2 Gene: BRCA2 (breast cancer 2, early onset) is a protein-coding gene.
These genes are most often tested together. If a BRCA1 or BRCA2 mutation has been identified in a family member with breast and/or ovarian cancer, then that specific mutation can be tested in other family members to assess their risk.

GeneReviews, an international point-of-care resource for busy clinicians, provides clinically relevant and medically actionable information for inherited conditions in a standardized journal-style format, covering diagnosis, management, and genetic counseling for patients and their families. Both BRCA1 and BRCA2 belong to a class of genes known as tumor suppressor genes that function to prevent the growth of cancerous cells.
Their risk of developing breast and/or ovarian cancer is so high, and so specific to those cancers, that many mutation carriers choose to have prophylactic surgery. The BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. BRCA2 is considered a tumor suppressor gene, as tumors with BRCA2 mutations generally exhibit loss of heterozygosity (LOH) of the wild-type allele.

The BRCA2 gene provides instructions for making a protein that acts as a tumor suppressor. Tumor suppressor proteins help prevent cells from growing and dividing too rapidly or in an uncontrolled way. The BRCA2 protein is involved in repairing damaged DNA. In the nucleus of many types of normal cells, the BRCA2 protein interacts with several other GeneReviews, an international point-of-care resource for busy clinicians, provides clinically relevant and medically actionable information for inherited conditions in a standardized journal-style format, covering diagnosis, management, and genetic counseling for patients and their families. 2021-03-31 · Excerpted from the GeneReview: BRCA1- and BRCA2 -Associated Hereditary Breast and Ovarian Cancer. BRCA1- and BRCA2-associated hereditary breast and ovarian cancer syndrome (HBOC) is characterized by an increased risk for female and male breast cancer, ovarian cancer (includes fallopian tube and primary peritoneal cancers), and to a lesser extent BRCA1 and BRCA2 hereditary breast and ovarian cancer.
