BRCA2 and BRCA2 (/ˌbrækəˈtuː/) are a human gene and its protein product, respectively. The official symbol (BRCA2, italic for the gene, nonitalic for the protein) and the official name (breast cancer 2) are maintained by the HGNC. Orthologs, styled Brca2 and Brca2, are common in other mammal species.BRCA2 is a human tumor suppressor gene (specifically, a caretaker gene), found in all humans; its protein, also called by the synonym breast cancer type 2 susceptibility protein, is responsible for repairing DNA.
BRCA2 and BRCA1 are normally expressed in the cells of breast and other tissue, where they help repair damaged DNA or destroy cells if DNA cannot be repaired. They are involved in the repair of chromosomal damage with an important role in the error-free repair of DNA double strand breaks. If BRCA1 or BRCA2 itself is damaged by a BRCA mutation, damaged DNA is not repaired properly, and this increases the risk for breast cancer. Thus, although the terms "breast cancer susceptibility gene" and "breast cancer susceptibility protein" (used frequently both in and outside the medical literature) sound as if they describe a proto-oncogene or oncogene, BRCA1 and BRCA2 are "normal"; it is their mutation that is abnormal.
Women who have no family history of breast cancer and don’t carry the BRCA1 or 2 gene mutation, have only a 12% chance of getting breast cancer in their lifetime. But, women with BRCA1 have about a 65% chance of developing it by the time they turn 70; the likelihood is a little lower for women with BRCA2 at 45%. Now that you know how important BRCA1 & BRCA2 is and how it affects your cancer risk, what exactly is it? Scottsdale Healthcare’s Gynecologic Oncologist Dr. Mike Janicek explains what BRCA1 & BRCA2 is in the video below.

Michelle found out she has a gene which gives her high chances of breast and ovarian cancer, meets women with similar issues and talks to Lorraine about it with Dr Hilary Jones
www.elarasystems.com October is breast cancer awareness month, and while most people are aware of breast cancer, they may be unaware of certain factors which increase the risk of developing the disease. Individuals with a strong family history of breast cancer may choose to receive a gene test to assess these risks. A gene test looks for specific mutations in your BRCA1 or BRCA2 gene. A mutation in these genes can be inherited from either your mother or your father. BRCA1 and BRCA2 help control normal cell growth. Mutations in these genes may increase the risk of developing breast cancer. According to the National Cancer Institute: About 12% of women in the general population will develop breast cancer. However, about 45% of women who have inherited a BRCA2 mutation will develop breast...

EXPLORE THE RI ADVENT CALENDAR: http://rigb.org.uk/advent Mistakes in the "recipe" of your DNA -- if bits of code go missing, or get swapped or damaged -- could spell the difference between life and death. DNA often gets damaged by everyday processes within our bodies, but also from external factors such as UV radiation or tobacco smoke. Luckily, our bodies are well equipped to fix this damage thanks, in part, to the BRCA2 gene, found on chromosome 13. BRCA2 encodes for a large protein which carries out repair work on damaged DNA. It's no surprise then that if the BRCA2 is faulty, or missing, our cells can't repair themselves properly. As a result, the damaged DNA builds up and this can lead to cancer. In turns out, however, that faults on BRCA2 aren't necessarily such an advantage to c...
We aired a story a few weeks ago about the BRCA mutation, and breast cancer. Sarah Parker saw that story and wrote into the Viewers’ Voice.
Because harmful BRCA1 and BRCA2 gene mutations are relatively rare in the general population, most experts agree that mutation testing of individuals who do not have cancer should be performed only when the person’s family history suggests the possible presence of a harmful mutation in BRCA1 or BRCA2. There are options for Couples with known BRCA 1 and BRCA 2 genes: PGD is one of them.
Throw me hard so I hit the concrete,
Scream words that you never did mean.
Even I can't stand this evidence,
It's clear, so clear.
Ringing in my ears won't stop,
And you've been smiling all along
(Burnt out!)
(Words are weakening)
She's in it for the nicotine, boys.
More poise than perfect,
Not worth saving, only leaving.
Break me up so my heart is shattered,
Three words that you never did mean.
Even I can't stand this evidence,
It's clear, so clear.
Ringing in my ears won't stop,
And you've been laughing all along.
(Burnt out!)
(Words are weakening)
She's in it for the nicotine, boys.
More poise than perfect,
Not worth saving, only leaving.
I can sit in this room and breathe abused,
I can do without the warmth from you.
But your knifelike smile needs a victim,
Worth your while.
(Words are weakening)
She's in it for the nicotine, boys.
More poise than perfect,
Not worth saving, only leaving.
(A lonely victim)
I can do what stab wounds never do,
I can peal the skin back just for you, beautiful you.
