The BRCA1 mutation Analysis Sequencing is done to study the damaging mutations occurring in the BRCA1 gene. This gene is responsible for the production of proteins, which prevent the development of tumours in Humans. The mutations in BRCA1 though rare, increases the chances of developing cancer in people who inherit the mutated gene. It is known to cause cancers of breast and ovary in women. In men who inherit the harmful mutated BRCA1 there is increase in the chance of developing malignancies of the Prostate gland. To detect the mutation in the gene it needs to be extracted from the DNA
