Genetic profiling for better treatment outcome. Hype or real possibility. Introduction Genomic technologies that have taken shape in the last two decades have virtually altered the human understanding of intricate molecular processes that supports the delicate web of life on the planet. A wide range of sophisticated genetic assays and state-of-the-art sequencing technologies have allowed researchers to identify genetic events such as mutations that are closely linked to malignancies. This has given

healthcare providers unprecedented access to information that could a long way in achieving amazing results with regards to treatment and intervention outcomes (ASH Clinical News, 2015). The concept of personalized medicine based on individual DNA profiling is already helping doctors and physicians carry out highly accurate assessment of risk and arrive upon excellent cancer treatment and research outcomes (Orchard, 2016). Genomic profiling through high throughput DNA sequencing is allowing doctors and researchers identify rare genetic conditions easily and considering the fact that 1 in 10 Americans is affected by at least 1 of the 7000 known rare genetic conditions, this is a significant leap in medical technology in the entire history of mankind (Orchard, 2016). The benefits and prospects of genetic profiling: Doctors have traditionally relied on techniques such as amniocentesis to ascertain if the fetus that is developing inside the womb is carrying any genetic defects. Though reliable, amniocentesis is invasive in nature as it involves transabdominal insertion of a needle into the abdomen of the pregnant woman. With modern genomic profiling technologies doctors today can obtain traces of fetal DNA sample from a tiny blood sample of the mother and detect the presence of any fetal genetic problems. This is not just non-invasive and less traumatic than amniocentesis but also highly accurate, fast and easy to perform (Orchard, 2016). Similarly, researchers have established that genetic screening for the presence of epidermal growth factor receptor overexpression in lung cancer tumors lead to better treatment outcome. This is because such tumors exhibiting overexpression of epidermal growth factor receptor respond far better to certain drugs and doctors can make the most informed choice with regards to their prescription (Orchard, 2016). Genetic screening for entities such as phenylketonuria in

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
