There are many human genes in the body and two of the more prominent ones that have been linked to breast cancer are BRCA1 and BRCA2. These genes are often talked about and tested for simultaneously, but it is important to remember that they are different genes and are not identical. To get a better understanding of BRCA1 and BRCA2 gene testing, it is essential to learn about the differences of each. This is a part of your health that you must take an interest in, because it has been known to save lives. Simply being aware and knowledgeable about BRCA1 and BRCA2 genes can have an immense impact on your overall health.
What are BRCA1 and BRCA2?
BRCA1 and BRCA2 are both human genes, but they are different genes that occur inside the body. Both of these genes have the function inside the body of making proteins that re designed to suppress the growth of tumors. This means that both BRCA1 and BRCA2 genes have the function of repairing DNA, but this function can be impaired if these genes are altered or mutated in any way. This means that you can be at risk of mutated cells and cancer growth through DNA damage. That is why BRCA1 and BRCA2 gene testing has become so essential. These genes have the same function in the body, but they are not the same.
Heredity and BRCA1 BRCA2 Genes
Breast cancer has been found to be hereditary and can be passed on from one generation to the other. This is due to the fact that some BRCA1 and BRCA2 genes are more prone to mutation than others. Having inherited mutated BRCA1 and BRCA2 genes can put you at a much greater risk of breast cancer. These mutated BRCA! And BRCA2 genes can be inherited from either or both parents. It has also been found that mutated BRCA2 genes are also linked to ovarian cancer. It is possible for mutated BRCA1 genes to cause ovarian cancer, but not as frequently as altered BRCA2 genes.
Knowledge and Testing
Since BRCA1 and BRCA2 genes have such a strong connection to breast and ovarian cancers, it has become common practice for gene testing to be used as a preventative treatment. This means individuals that have mutated BRCA1 and BRCA2 genes will undergo preventive measures to ensure that these cancers are avoided.
