The Importance Of Risk Assessment In Genetic Counseling

1609 Words7 Pages

1. Describe risk assessment in genetic counseling Genetic risk should be estimated as precisely as possible as it is an important component of genetic testing and counseling, and for family decision making. It is always good to take out extra information from pedigree charts and genetic testing as it can improve the accuracy of risk assessment drastically. The risk can be calculated using Bayesian analyses. Among populations, families or individuals within the same family have significantly different probabilities of carrying a particular mutation. Genetic risk assessment is subject to modification as it is a population based estimate of probability at a particular time (it is because population based data and testing methods are being updated constantly, expansion of families, new offsprings and new clinical and genetic testing information are being added). Other factors that affect risk assessment are analytic or interpretive laboratory errors as they can alter the estimates of carrier frequencies, allele distributions ad other such parameters. Therefore, genetic risk is quantified systematically. The most often …show more content…

This idea was used by Galton and many others to promote selective breeding in humans to improve the human species. The Eugenicists described lack of education as familial feeble mindedness and rural poverty as shiftlessness. There was an overestimation of scientific difficulties in seeing whether traits are heritable and to what limit hereditary contributes to the trait as most human traits are strongly influenced by environmental factors and are even complex in their inheritance pattern. Though genetic counseling aims to help patients and families in managing pain and suffering caused by a genetic disorder , it should not be confused with the eugenic goal of decreasing the incidence and recurrence of a genetic

    Darwinists in turn, believed biology to be destiny and that if one's ancestors were unfit their children would be as well. Much like in evolution, Spencer assumed that the unfit populations would decline overtime due to their failure to compete, however paranoia led some Americans to speed up this process, introducing eugenics. Eugenics were supposed to improve men, ridding the undesirable traits of the unfit and changing genetic structure to create more fit individuals. The Eugenics movement in America took people of color, the mentally ill or disabled, LGBTQ individuals, and other members of society deemed unfit, and conducted experimentation ranging from forced breeding, involuntary sterilization, or institutionalization on them. Although the movement was eventually stomped out, it violated thousands of

    The twentieth century American eugenics movement was a social and scientific movement that sought to enhance the genetic quality of the human population through sterilization and selective breeding. Eugenics, the scientific practice and theory of planned breeding and racial purity, was widely popularized by an English polymath, Sir Francis Galton. Galton, cousin of Charles Darwin, supported the idea of selected marriages and breeding, which then spread to countries across the globe. The social Darwinist philosophy of the early twentieth century and the newly developing science of genetics both had an impact on the eugenics movement as it rose in popularity in the United States. The movement was backed by many well known scientists, politicians,

    Eugenics is the study of how to arrange reproduction within a human population to increase the occurrence of heritable characteristics regarded as desirable. This belief that eugenics was not scientific was shown by a scientific article entitled "The Progress of Eugenics." In this article, biologists state that eugenics is not scientific because people will never know what traits will be desired in the future, and it is best to just let natural selection take its course. This is shown by biologist Huxley when he states that there is "no hope that mere human beings will ever possess enough intelligence to select the fittest. " This shows that some aspects of the Progressive Era, such as the belief that eugenics was bad, were

    Eugenics is the science of using artificial selection to improve genetic features of the population. It is thought that improvement of the human race can be seen through sterilization of people who exhibit undesirable traits and selective breeding. Often called Social Darwinism, the concept was widely accepted during the time of World War I. It quickly became a taboo after World War II when Nazi Germany used it as an excuse for genocide. The thought of improving the human race by manipulating who is allowed to breed can either be appalling or compelling.

    Therefore, if two parents are carriers of a certain gene that will disable their child, they can modify that gene to make a child that will not have that disability. As well as some parents will have designer babies to save another child they already have with a certain disease. In this method, parents will choose their child’s blood type and such in order for them to match that other diseased child and potentially give them their blood, marrow, and even organs. Genetically modifying a child’s chance of disease ensures that a child may live a life without potential disease and disability that they may have been more prone to had their parents’ not used this method. This also ensures a healthy life for a child that had a greater potential of having a medical condition due to their parents being carriers of that particular gene.

The Enterprise stumbles upon an isolated colony that is genetically engineered to be the perfect society—they have eradicated disease, live in harmony with their environment (and each other), and are designed specifically to fulfill a defined purpose in the society. Nearly everything is accounted for and very little occurs that is unexpected. The colony’s society is perfectly balanced, but it is also extremely fragile. One change could destroy the society, could let it fall to chaos.
