testing. Some of the benefits of genetic testing include assisting doctors in making healthcare decisions, providing patients with clarity for an illness that would otherwise go undiagnosed, and screening newborn babies for specific diseases or mutations. Despite its benefits, however, there is a plethora of complications that accompany genetic testing. Preimplantation Genetic Diagnosis, potential discrimination, and unnecessary anxiety and even depression…

differentiate between two different persons. Pros and Cons The pros of gene testing are its possible benefits of their health care. Results can soothe one’s uncertainty and help people make better decisions like stopping unnecessary health checkups or point a person towards available treatments and preventions. Gene testing can also determine the biological parents of a child or the identity of natural disaster victims. One the other hand, some tests are expensive and are not affordable for…

Currently, there is one procedure widely used to detect mutations that could lead to heredity diseases or genetic diseases harmful to the future child’s health. When a woman wants to be a mother, she can choose in vitro fertilization (IVF) where the eggs of the mother are removed and mixed with sperm in a laboratory ("Fertility Treatment: In Vitro Fertilization (IVF)"). It is during this time embryo selection can occur if the mother wishes. The mother can choose a procedure called…

2016). Smoking tobacco and exposure to other carcinogens increases human risk for cancer significantly by enhancing DNA mutation rates. Different carcinogens cause slightly different types of DNA damage in humans that eventually lead to cancer (Ehrenberg, 2016). These unique patterns of mutations that occur in different types of cancer tissue are what makes each carcinogenic mutation unique and leave behind their own mutational signature on the cancer genome. These signatures can be used as a…

environments will tend to produce similar outcomes. Others think its course follows unpredictable twists and turns, and that the same starting point can lead to very difficult results. Say we rewound time, and took the history of our planet back some million years. When we hit play, would we end up with the same kind of species and diversity we have today? Whether…

The development of thyroid cancer arises from mutations in either receptor tyrosine kinases or effectors involved in those pathways. In particular, papillary carcinomas generally have alterations in the mitogen-activated protein kinase pathway (MAPK). For example, RET stands for "rearranged during transfection." RET is expressed in high amounts from the C cells in the thyroid, and the RET proto-oncogene is activated by fusion of the RET TK domain with the 5′ sequence of one of different…

Gene mutation is a permanent alteration in the DNA nucleotide sequence, such that the sequence is different from what is commonly found. Mutations range in size; they can affect anywhere from a single base pair, to a large segment of a chromosome. Gene mutations can be categorized in two major ways, hereditary and acquired or somatic mutation. Hereditary mutations are mutations inherited from a parent. These mutations are present in virtually every cell of the body, and are present throughout…

Fatal Familial Insomnia is passed on through generations. The chances of a parent passing on the genetic mutation is 50%, as stated by “rarediseases.info.nih.gov” updated in 2016. Since FFI is passed on throughout generations, if a parent has two children, one of them is almost guaranteed to get FFI, except for in rare cases. The mutation occurs in the 20th chromosome which leads to other problems in th body. FFI doesn’t lead straight to death, there are multiple things leading up to the final…

Introduction Osteogenesis imperfecta describes a group of genetic disorders that are colloquially known as “brittle bone disease” and is estimated to affect around 7 out 100,000 people around the world. As the name suggests osteogenesis imperfecta is characterized by imperfect formation of the bones that leads to frequent fractures or breaks from minor trauma (Rauch et al., 2004). Depending on the severity of symptoms the impact to an affected individual 's life can differ. This paper will…

of the cells is due to a point mutation and the genome of the infected cells can’t be changed we must look into the biochemical pathways that HU affects. Throughout the literature the main theme has been discussing…
