Visualization of genomic sequence in BRCA1 and BRCA2
Abstract
Heredity is the main reason of breast cancer in women and mutation or genetic variations also another reason for the spread of breast cancer. Heredity and genetic variations are responsible 5%-10%, 30%-50% respectively. There are 90% chances of developing neoplasm by the mutations. The effect of BRCA1 and BRCA2 may leads to the variations in DNA therefore it should be in limited amounts so that there will be minimum changes in DNA. The BRCA1 and BRCA2 helps to repair or heal the DNA sequences but it grows rapidly and causes cancer. BRCA1 and BRCA2 can carry out for the patients who have the past occurrence (family history) of the carcinoma. The past history is done by the clinical evidence or diagnosis of the particular patient.For the diagnosis, we can use the various methods blood test, mammogram, breast ultrasound, biopsy etc.The ayurvedic and allopathic treatment is useful for the cure of various kinds of cancers, the ayurvedic medicines such as herbal drugs are helpful because they have the anti-cancer properties as well as the allopathic treatment is also required because the tumour is suppress by these and the examples of pharmacological treatment like alkylating agents, plant producers, etc. BRCA1 and BRCA2 are cancer suppressor genes, the sequence of these coding regions shows no similarity to the proteins with each other. If one copy in the gene is mutated, the result becomes hereditary and transfer breast and ovarian cancer fronm one generation to other generation.
