Genetic testing done on normal, non-tumor cells (usually blood or saliva) to find inherited mutations in genes, such as BRCA1 and BRCA2, is known as germline testing. Germline testing helps to identify mutations that are present at birth and/or passed down from a parent.

Brca1 Gene Testing What it Means for Men who Carry a BRCA Gene Fault | Pink Hope |. gambar. A known BRCA1, BRCA2, or other inherited mutation in your family Genetic testing for hereditary breast and ovarian cancer looks for mutations in the BRCA1 and BRCA2 genes. Your doctor might suggest testing using a multigene panel, which looks for mutations in several genes at the same time, including BRCA1 and BRCA2. The BRCA gene test is a blood test that uses DNA analysis to identify harmful changes (mutations) in either one of the two breast cancer susceptibility genes — BRCA1 and BRCA2. People who inherit mutations in these genes are at an increased risk of developing breast cancer and ovarian cancer compared with the general population.

Gross deletion/duplication analysis determines gene copy number for BRCA1 coding exons 1-22 and BRCA2 coding exons 1-26. Clinically significant intronic findings beyond 5 base pairs are always reported. Intronic variants of unknown or unlikely clinical significance are not reported beyond 5 base pairs from the splice junction.
