Genetic Defects Of Gene Therapy

Gene therapy is a very controversial topic that has been discussed in the last five years and is being heavily studied to help cure cancer. Gene therapy is a technique aimed at treating genetic disorders by introducing the correct form of the defective gene into the patient’s genome (Dunlop et al., 2010).

Human gene therapy is a procedure that is currently being used to help fight diseases with no known cures. Gene testing removes a gene that causes a disease and replaces it with a healthy copy of that gene. By placing a healthy copy of the gene inside the patient’s body, that gene can help fight any diseases, such as different forms of cancer, inherited disorders, immune system discords or viral infections (AIDS). Once inside the cell, the genes produce what the patient lacks, it kills the diseased cells and it activates cells in the immune system.

DNA has about 12 million single nucleotide polymorphisms and thousands of copy number variants, most of which are not harmful. Sometimes these mutations in genes can cause genetic disorders that end up altering or inhibiting protein function. Gene Therapy focuses on correcting the mutated genes usually by inserting a normal gene into the genome. Researchers treat these diseases this way by repairing dysfunctional gene or by providing copies of the missing gene. They isolate the normal DNA and package it into a vector. Other ways include replacing the abnormal gene with a normal one, repair the mutated gene, or altering the regulation of a certain gene. As of right now, reparative results have been marginal, there is potential of gene therapy treating single-gene disorders.

Gene therapy provides many benefits to the patients who undergo it. Biotechnologists believe that a genetic disease can be removed with this treatment. For example, on the U.S. National Library of Medicine website, it states, “Researchers are testing several approaches to gene therapy, including: Replacing a mutated gene that causes disease with a healthy copy of the gene. Inactivating, or ‘knocking out,’ a mutated gene that

Some people may wonder what gene therapy is. Gene therapy is the replacing of defective or missing genes with normal genes in order to cure the disorder. In the future, this technique may be used to prevent or treat a disorder by inserting

Gene therapy is the insertion of normal or genetically altered genes into cells to replace defective genes. The gene is usually inserted into

Demolishing genetic diseases from the human race has been and always will be a key role in science. However, there comes a point in time when moral standards have interjected the betterment of cleansing genetic diseases. One of the many branches of science that has the complete capability to exterminate our destiny of any genetic diseases, gene therapy, is being silenced due to the curse of society’s moral standards. There is a very narrow line in what is not morally correct and ethical to standards of people; causing the advancement of procedures like gene therapy to be narrow. The only explanation to gene therapy awaits on what we, as a community, can bring about for the future generations, but this is

Fifty years after the idea of gene therapy was first proposed, gene therapy has become a possible treatment for a couple different diseases. Before this treatment was approved, some serious unfavorable effects were found in clinical trials. However, these effects fueled more basic research in order to improve, in efficiency and safety. Gene therapy has been used for patients with blindness, neuromuscular disease, hemophilia, immunodeficiencies, and cancer.

In the future, medical professionals hope to be able to treat or even eradicate a disorder by inserting a new gene into the cell via drug or surgery that will combat or even fix the mutation in the DNA that causes that disease. This therapy is still in the very early stages of experiments, and the ethical questions surrounding it prevents much progress from being made at all. There are many potential health complications surrounding this type of approach: scientists still do not completely understand how genes work and if they can be replaced. CRISPR will be a major tool used in gene therapy. CRISPR, which stands for , is a unique technology that lets geneticist and medical researches edit part of the genome by pinpointing a certain area of DNA and adding DNA, removing DNA, or altering the DNA sequence (Your

Whether gene therapy should be allowed to be used in practice is currently a very controversial topic. In my opinion, I do not think that it should be allowed. Gene therapy is a technique where genetic material is inserted into a patient to replace missing or defective genes. Gene therapy can be further broken down into two categories: somatic and germline. From there, somatic gene therapy can be approached in two ways: in-vivo and ex-vivo. For the process of gene therapy to begin, the proper vector needs to be acquired. Once a vector is chosen, the vector delivers the new gene into the target cell. Then, the target cell becomes infected with the vector. Next, the vector’s genetic material is inserted into the target cell. Then finally, functional

There are two types of gene therapy; germline gene and somatic gene therapy. Germline gene therapy is considered to be a safer option for humans. This method makes changes to the gamete cells that are used in the reproductive process thus, the functional genes need to be inserted into the chromosomes. Somatic gene therapy is when genes are transferred to body cells by inserting vectors into a person’s body. There are three things that gene therapy can do; replace a mutated gene that causes a disease with a healthy gene, deactivate a mutated gene that is not able to function properly, or introduce a new gene into the body to prevent diseases. There has been a clinical trial in the past where over 3000 people were treated with gene therapy and the results were good however, this treatment method has serious health

Li, and Huang discuss the controversial topic of gene therapy by first providing a factual summary of gene therapy. Their introduction goes into the specifics of the types of vectors (carriers that deliver a gene to target cells) used to transfer genes in order to aide damaged proteins. Afterwards, they transition into the detailed of process of gene therapy. They start this off with naked DNA and state it is the simplest approach to nonviral transfers and the least toxic method. However, despite being the least toxic and a nonviral transfer it does not have as great of an effect as Cationic lipids. Cationic lipids have been used in various experiments but are known to be safe only when administered in small doses. Furthermore they go into

Gene therapy is a technique that allows for the modification of genes to treat or prevent disease and may become a viable way for doctors to treat a disorder without the need of drugs or surgery. This technology is still experimental, being only about three decades old with the first successful human trial occurring in 1990 when Dr. William French Anderson treated Ashi DeSilva for Adenosine deaminase deficiency (ADA deficiency), which is a genetic, metabolic disorder which causes immunodeficiency. Researchers are testing several approaches to gene therapy, which include replacing mutated, disease-causing genes with a healthy copy of the gene, inactivation a malfunctioning gene, and introducing new genes into the body that will help fight diseases. Over the last two decades, about 2,000 trials have been conducted or approved and future prospects for this technique are encouraging, include the engineering of human genetics in ways that may prove controversial and difficult to predict. This paper will explain how gene therapy works, what it has accomplished so far, its future and current hurdles, and what this all means for our species.

In the medical journal article “Harlequin Ichthyosis”, the authors Claire A. Scott, Shefali Rajpopat, and Wei-Li Di explain how “ABCA12 mutations underlie defective lipid transport, reduced protease regulation and skin barrier dysfunction." The first known case of HI was discovered in 1750, and was documented in the diary of Reverend Hart. The effects are apparent at birth and are commonly clinical. The entire body is born covered in a compact layer of white plates of scales separated by deep red cracks. The thickened skin, usually restricts movement and causes limb contractures, inevitably causing digital necrosis and autoamputation.
