Description:

In this article, the writer notes that mutations of the BRCA1 are known to be a cause in early onset breast-ovarian cancer, prostate cancer and colon cancer. The writer describe and experiment that aimed to sequence the exon containing the BRCA1 gene in order to identify disease causing mutations and then clone the gene to accept or reject heterozygosity shown in the sequence on the chromatogram. Salivary DNA was collected, amplified, and sequenced so that the sequence of the chromatogram obtained could be compared with the normal sequence to identify the positions of mutations. The writer discusses that the results obtained helped identify mutations and how to find their positions so that a better understanding of gene mutations and how to find them is acquired. The writer concludes that with the growing knowledge of gene mutations this brings us one step closer to finding a cure.

From the Paper:

"The BRCA1 gene was initially discovered in 1990 by Mary-Claire King, however, it wasn't until 1994 that a team of scientists located and amplified the gene. The reason why it took so long to locate the gene was due the fact that it only accounts for only 5% of all breast Cancer Cases. The gene is 100kb long and is located on the long arm of chromosome 17 at locus q21. It is a tumor suppressor gene which, with the interaction of other tumor suppressor genes, helps repair damaged DNA and control cell growth, therefore, keeping genomic stability.
"In response to damage BRCA1 produces a product which is activated and interacts with the BRCA2 and RAD51 to repair the broken DNA. The BRCA2 gene in another gene which when mutated causes breast cancer in men and women whereas BRCA1 only causes breast cancer in women."
