BRCA1 Genetic Analysis

Although the BRCA1 gene currently acts as a predictive factor with regards to breast cancer, this may not always prove to be the case. There are two major reasons for this. One of these reasons is that genetics can fluctuate and mutate over generations, so that the link may break and cease to hold value over time. The second of these is because we have not fully finished analyzing the human genome, and we may find out something disproving this marker as a genetic marker, instead attaching that analysis to some other gene (presumably either one that causes the BRCA1 marker, or one that coincidentally exists alongside that marker, either outcome allowing for it to have been mistaken for a marker.

The more likely of these, however, is the
