The normal value for BRCA1 test is >100kU/l, and this range is only for all age groups of females.

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 tumors 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.

The presence of a BRCA1 or BRCA2 mutation means that the person tested is at an increased risk for developing hereditary breast and/or ovarian cancer syndrome. It also indicates that the individual’s family members may be at increased risk for breast or ovarian cancer.

However, even within a family with the same BRCA mutation, not everyone will develop cancer and those who do may develop it at different times during their lives.
