BRCA Share is structured as a user group. Any participant in BRCA Share is expected to timely share their BRCA1 and 2 gene variant data with other users and abide by other customary obligations. 2020-09-21 · Most inherited cases of breast cancer are associated with two abnormal genes: BRCA1 (BReast CAncer gene 1) or BRCA2 (BReast CAncer gene 2). Women who inherit a mutation, or abnormal change, in either of these genes — from their mothers or their fathers — have a much higher-than-average lifetime risk of developing breast cancer and ovarian cancer. Both BRCA1 and BRCA2 belong to a class of genes known as tumor suppressor genes that function to prevent the growth of cancerous cells.

They have function in DNA repair processes and thus they are tumor suppressor genes. There are hundreds of mutations identified in these genes. Functional deficiencies due to these mutations impair DNA repair and cause irregularities in the DNA synthesis. The BRCA gene test is a blood test that uses DNA analysis to identify harmful changes (mutations) in either one of the two breast cancer susceptibility genes — BRCA1 and BRCA2. People who inherit mutations in these genes are at an increased risk of developing breast cancer and ovarian cancer compared with the general population.

En nyligen publicerad metaanalys anger att män med mutation i BRCA1 och BRCA2 har en ökad risk för prostatacancer, vilket i första hand beror på en ökad risk associerat med sjukdomsassocierade varianter i BRCA2 (Oh et al., 2019). Mutations in BRCA1 and BRCA2 are strongly implicated in some hematological malignancies. BRCA1 mutations are associated acute myelogenous leukemia and chronic myelogenous leukemia.

Maria och Alexandra, mor och dotter bär båda på BRCA mutationen.

BRCA1 (BReast CAncer gene 1) and BRCA2 (BReast CAncer gene 2) are genes that produce proteins that help repair damaged DNA. Everyone has two copies of each of these genes—one copy inherited from each parent. BRCA1 and BRCA2 are both DNA-repair genes. They hold the code for BRCA1 and BRCA2 proteins, which repair DNA damage in cells. When the BRCA1/2 genes are mutated or abnormal, they create malfunctioning BRCA1/2 proteins, which result inadequate repair of DNA damage. This can cause normal cells to turn cancerous. What are BRCA1 and BRCA2?
