Can gene mutation cause breast cancer?
BRCA1 and BRCA2: The most common cause of hereditary breast cancer is an inherited mutation in the BRCA1 or BRCA2 gene. In normal cells, these genes help make proteins that repair damaged DNA. Mutated versions of these genes can lead to abnormal cell growth, which can lead to cancer.
Which gene mutation causes cancer?
The most commonly mutated gene in people with cancer is p53 or TP53. More than 50% of cancers involve a missing or damaged p53 gene. Most p53 gene mutations are acquired. Germline p53 mutations are rare, but patients who carry them are at a higher risk of developing many different types of cancer.
How likely are you to get breast cancer if you have the BRCA gene?
The average lifetime risk of breast cancer for women is about 12%. For women who have a BRCA1 or BRCA2 mutation, the risk of developing breast cancer in your lifetime is between about 69% and 72% — about 6 times greater than that of a woman who does not have the mutation.
What is MTHFR mutation and what does it mean?
MTHFR stands for Methylene-Tetra-Hydro-Folate-Reductase and is an enzyme that helps metabolize homocysteine. The heterozygous MTHFR gene mutation means the mutation is on one copy of the gene, while Homozygous means it is on both copies of the gene.
How did you treat the MTHFR mutation?
Consume more folate and vitamin B12. Consuming more folate in your diet may aid with methylation.
Is genetic testing necessary if you suspect MTHFR mutation?
Although it is possible to identify an MTHFR gene mutation through genetic testing, organizations such as the American Heart Association recommend against screening for common MTHFR gene variants in regards to cardiovascular risk.
What the Heck is the MTHFR gene mutation?
MTHFR stands for methylenetetrahydrofolate reductase. It’s getting attention due to a genetic mutation that may lead to high levels of homocysteine in the blood and low levels of folate and other vitamins. There’s been concern that certain health issues are associated with MTHFR mutations, so testing has become more mainstream over the years.
