Bolton said, noting that although germline mutations in the BRCAl and BRCA2 genes
are rare in the general population, they are present in 10%-15% of those with ovarian cancer.
Mutations in the BRCA1 or BRCA2 genes
are responsible for around 5% of the 44,000 cases of breast cancer diagnosed annually in the UK and for more than 5% of the 6,615 cases of ovarian cancer diagnosed each year.
The efficacy of the operation for preventing these cancers had not been evaluated according to mutation type, even though 17 to 39 percent of all BRCA mutation carriers have a BRCA2 gene
The Cancer Research Campaign has spent 12 years and pounds 10 million researching the BRCA2 gene
to develop a genetic test for breast cancer.
The patent is the first to issue on the BRCA2 gene
in the United States.
The BRCA1 and BRCA2 genes
are usually responsible for generating molecules inside cells that help to repair DNA.
One of the 12 BRCA mutation-positive patients carried both the BRCAl and BRCA2 gene
Women with a defective BRCA1 or BRCA2 gene
are up to seven times more likely to develop breast cancer than those without the mutations.
The mother of two carries a fault in the BRCA2 gene
and could benefit from the ground-breaking research in the future.
But for women who don't harbor a mutation in either the BRCA1 or BRCA2 gene
, the normal forms of which suppress cancer, the high cost of MRI may not be justified, says Christiane K.
But doctors know that 40pc of early onset, aggressive prostate cancers are linked to inherited factors, some of which are due to alterations in the BRCA2 gene
FEARS Michelle worries she may have passed on the BRCA2 gene
Singer made painful decision to undergo hysterectomy due to mutated BRCA2 gene
with Dr Craig Lennox FORMER Liberty X singer Michelle Heaton has the BRCA2 gene
, which means she has a 40 per cent chance of developing either breast or ovarian cancer.
She has the BRCA2 gene
, which means she has an extremely high probability of getting both forms of cancer.
Researchers have discovered that women who do not have a BRCA1 or BRCA2 gene
mutation but have a female first-degree relative (mother, sister, or daughter) with a BRCA mutation do not have an increased risk of breast cancer compared to women with no personal or familial mutations.
