Genetic diseases, as defined by The University of Utah, are either a mutation in one gene, or the addition or subtraction of a chromosome or set of chromosomes. Examples of genetic diseases include various cancers and Down syndrome. No one can...
Each cell within the human body contains DNA, made up of a sequence of billions of chemicals called base pairs. The sequence of specific base pairs codes for thousands of genes found on two sets of 23 chromosomes--large pieces of DNA, each...
Genetic tests are done either to diagnose genetic disorders or identify risks associated with developing a disease. Testing problems range from the accuracy of the genetic tests and oversight of the testing labs, to the growing market for...
Due to recent discoveries of new genes and the development of new testing methodologies, the availability of genetic testing has increased dramatically. Several companies now offer direct-to-consumer genetic testing through which individuals can...
DNA provides the blueprint for life: it codes the information required for cells to generate the compounds required for growth, development and metabolism. Genetic diseases may develop due to abnormalities or deletions of single genes, or large...
The availability of genetic testing has boomed recently. Consumers can now order genetic tests via the Internet without a doctor's involvement. Although these tests are designed to help people by providing more information about their health...
With the advent of new testing methodologies and increased availability of tests thanks to direct-to-consumer genetics companies and the Internet, more people are able to access a wide range of genetic tests. Although these tests can provide...
Genetic testing can serve many different purposes, from diagnostic testing for symptomatic disease to predictive testing for diseases that won’t set in for years. When used properly and in the context of adequate informed consent, the...
Numerous genetic diseases can affect the elderly. According to the U.S. National Library of Medicine and the National Institutes of Health, or NIH, genetic diseases or disorders are caused by gene variations or mutations, and many diseases have a...
Newborn genetic screening is an effort to discover adverse genetic conditions in infants, according to the Genetics Department at the University of Utah. The existence of this program enables doctors to get ahead of the diseases by planning early...
A genetic disorder is caused when an abnormality in the genetic framework of an individual is present. Genes are passed from parents to child. When a mutation of a gene occurs, it prevents it from developing normally. Some genetic disorders are...
People consider having genetic testing done for several reasons. People who have a family history of a genetic disease, couples planning to get pregnant and pregnant women concerned about genetic anomalies in their baby may all consider genetic...
Genetic diseases occur because of abnormal genes or chromosomes. Causes of genetic diseases include mutated genes, chromosome duplication, missing chromosomes and a portion of a chromosome erroneously attaching to another chromosome. Some genetic...
Genetic diseases have a wide spectrum of presentations ranging from mild in individuals unaware of their condition to severe, resulting in death at a young age. Single-gene disorders are caused by mutations that affect individual genes. Examples...
Medical experts believe alcoholism stems from a combination of genetic and environmental factors. A strong genetic contribution to alcoholism shows in the three- to four-fold higher risk for alcoholism among first-degree relatives of an alcoholic...
A genetic disorder is a medical condition caused by a mutation in an individual’s genomic makeup. Most genetic disorders are caused by a mutation in the DNA sequence of a single gene, gross breaks in individual chromosomes or the addition of...
There is no single simple cause for alcoholism. Rather, medical experts believe that alcoholism develops from a combination of interrelated genetic and environmental factors. The Department of Psychology at the University of Minnesota reports a...
Genetic diseases are present in 8 percent of live births. Based on a population study reported in the "American Journal of Human Genetics" in May 1988, about 0.4 percent of the population have a single gene disorder, 0.2 percent have a chromosomal...
Almost all human disease has a genetic basis, even those associated with lifestyle choices such as obesity, heart disease and alcoholism. So why do genetic diseases occur in some people, but not in others? The answer lies in the human genome. ...
Alcoholism, which is defined by inability to stop drinking, drinking in the presence of severe psychological and physiological issues, high tolerance and withdrawal symptoms, affects approximately 5 percent of the United States population,...
The brain is able to control the actions of skeletal (voluntary) and smooth (involuntary) muscles by sending signals that stimulate muscles to contract or relax. Genetic neuromuscular disorders disrupt this system. Some of these disorders are...
Genetics is the process in which parents pass certain genes onto their children. An abnormal gene that is passed down through the family may have only minor consequences, or it may have a dramatic impact on one's quality of life. Abnormal genes...
The term Sephardic describes people of Jewish descent whose ancestors came from Spain, Portugal, North Africa and some regions of the Mediterranean, according to a 2009 article written by Talia Bloch for Haaretz.com, but the term is often used to...
The skin is a complex organ made up of a number of tissue types, which work together to maintain the integrity of the skin and form a barrier between the environment and the rest of the body. Skin contains thousands of follicles, which contain...
No matter how hard you work out, sooner or later you will hit your body's genetic limit for muscle mass. This limit varies per individual and declines with age. With a proper bodybuilding routine, however, you can ensure that you maximize muscle...
The mouth, also known as the oral cavity, describes the part of the body bound by the cheeks, lips, palate and floor of the mouth. The mouth contains the tongue, teeth, the gums and bones supporting the teeth and the salivary glands. Genetic...
Genetic diseases or disorders result from a mutation in the genes (DNA). Sometimes, one gene can be mutated or a group of genes become mutated. In fact, some genes are passed within families. These genetic alterations can significantly affect a...
Genetic diseases are caused by gene mutations that are inherited from one or both parents. Certain genetic diseases can cause abnormalities in the teeth, affecting the rate of development of primary (baby) and secondary (adult) teeth or their...
Hypertension, or high blood pressure, appears to have a strong genetic contribution. It can occur as an isolated symptom, in the case of essential hypertension, or as one of many symptoms in a variety of genetic syndromes. Syndromes that affect...
