Genetic disorder

inheriting any of the 3,000 known genetic disorders. But such predictions are similar to casino odds. Doctors can’t predict which smokers will actually develop lung cancer, which individual will have a premature heart attack or which child actually inherited a defective gene. Genetic probes, however, will change predictive medicine. The probes are synthetic versions of genes that cause disease. Tossed into a test tube with a small sample of a person’s own genetic material—his DNA—the probes cling

Down syndrome is a genetic disorder that affects several people. Chances are, you have met or have seen somebody living with down syndrome. Down syndrome is caused when an individual has a full or partial copy of chromosome 21. This additional piece of genetic makeup leads to changes throughout the body. Some of the notable changes are having a low muscle tone, small stature, an upward slant to the eyes, and a deep crevice in the center of the palm. Down syndrome does not affect one single part of

Initially, medical genetics was devoted largely to the study of relatively rare single-gene or chromosomal disorders. But as result of advances in molecular medicine, genetics is now able to provide information about more common and accordingly more costly diseases such as Alzheimer’s disease, cancer, and coronary artery disease. It is the predictive ability of genetic tests for these diseases that makes them especially intriguing in adopting

Joubert Syndrome is a brain development disorder that affects different parts of the body. This disorder is caused by underdeveloped parts of the brain and a distorted brain stem. People with this condition have a hard time controlling and coordinating their movements. Joubert Syndrome is caused by a mutation of cells during cell development that prevent the cilia of the cells from fully developing. The condition is an autosomal recessive trait that are carried on X chromosomes in an X-linked recessive

Overview Noonan syndrome is a disorder caused by a genetic mutation that causes various parts of the patient’s body to develop abnormally. The condition occurs when a parent passes on an affected gene to their child that produces constantly active proteins, leading to a disruption in the process of normal cell division and growth. Science currently knows of eight genes in which a mutation can cause the disorder. In some cases, there is no family history and the mutation is spontaneous. Symptoms

embryos would outweigh the potential hazards. CRISPR/Cas9, a system of molecules used to change the DNA in adult human cells and animal embryos, is used to eradicate devastating genetic diseases in humans before birth. CRISPR identifies the target DNA, which shows Cas9 the correct strands to slice (“CRISPR Treats Genetic Disorder”, 2016). This process has

Genetic alteration is defined as the deliberate modification of the characteristics of an organism by manipulating its genetic material, sterilisation is defined as the process of making someone completely unable to reproduce. So, should individuals with diseases be told, sterilised or genetically altered? Sterilisation can prevent spreading of diseases to the next generation but it hinders the chance of reproduction. While altering, DNA can lead to many horrifying events, such as viral diseases

The first issue about genetic testing is the discrimination that can come out from your results that all questions that people have are to understand if they should really beginning their tested” because information about individuals Health can be used to discriminate against them the Privacy provisions of u.s. health insurance portability and Accountability Act of 1996( HIPAA) was revised in 2003 to create a category of protected health information that can be used or disclosed only under certain

Neurofibromatosis is a “genetically inherited disorder of the nervous system.” (Nordqvist, 2016) This disease causes the development of tumours in the nervous system, primarily involving the brain and the spinal cord, but may lead to the growth of tumours elsewhere on the body. There are three different types of Neurofibromatosis (NF) these involves, Type 1 NF (Von Recklinghausen NF), Type 2 NF (Bilateral neurofibromatosis NF) and Schwannomatosis. Information, regarding the various components of

Priotities of Gene Therapy Gene therapy is a relatively new area of medicine that attempts to apply recent advances in molecular biology, genetics and biotechnology to the treatment of human diseases. Gene therapy uses a set of approaches to the treatment of human disease based on the transfer of genetic material (DNA) into an individual. Gene delivery can be achieved either by direct administration of gene-containing viruses or DNA to blood or tissues, or indirectly through the introduction
