Human Genetics and Genetic Disorders

Human genetics is the basis of the inheritance in human beings. Encompassing a wide variety of overlapping fields that include classical genetics, molecular genetics, extogenetics, and multiple other types of genetics, it is a very important aspect of biological science.

Usually the behavioral pattern in human beings is determined on the basis of genetic factors. Genes are the basic factors that influence the physique as well as psychology of a person. That is reflected in their behavioral patterns. Moreover the study of genes could be very useful in determining the answer to certain questions relating to human anatomy and psychology. At times the detection of diseases is also dependent on the genes. It has been scientifically established that many critical diseases like the diabetes often have genetic basis. Read more >>

Narcolepsy Genetic Disorder - Influencing Genes

Narcolepsy is classified as a chronic sleep disorder that interferes and disrupts the usual sleep-wake cycle. Narcolepsy can affect people of all ages; however it often first appears in adolescence.

There are many symptoms of narcolepsy which include excessive daytime sleepiness. People who suffer from narcolepsy genetic disorder may feel very tired all day as a result they may often feel like going to sleep during the day. Affected individuals can also suffer from 'Sleep attacks' which can occur during unusual times such as during a conversation or during eating a meal.

A 'Sleep attack' can vary in duration and may last for a few minutes or over an hour.

One more commonality of narcolepsy genetic disorder is a reduction in muscle tone which is usually as a result of strong emotions like surprise, laughing or anger. This extreme muscle weakness may lead to the affected person falling over which may lead to injury. Read more >>

Common Human Diseases That Are Caused by Genetic Disorders

Although all the diseases are not caused by bacteria or viruses but many develop because of our genes that is our genes are responsible for many acquired and acute diseases.Information about various diseases can be taken from medical applications,medical animations and disease movies.

Let\'s first understand what genetic disorders are.Environmental and genetic factors are responsible for the development of the disease.Genetic disorders are caused by abnormalities in an individual\'s genetic material known as genome.The genetic disorders can be classified into four types.

Common Health and Genetic Disorders in Rottweilers

Rottweilers: these dogs may look pretty tough, stocky and powerful from the outside but when it comes to health problems they sure may have their own sets of problems. For this reason, it cannot be repeated enough the importance of purchasing Rottweiler dogs from reputable breeders that test their breeding specimens for hereditary disorders. Breeding specimens that test positive to any hereditary disorders are therefore eliminated from the breeding pool. This significantly lowers the chances of encountering any genetic disorders.

Common Health Problems in Rottweiler Dogs

Orthopedic Disorders

-Hip Dysplasia

This genetic disorder is a common occurrence in large and giant dog breeds. It tends to occur when the hip bone and socket bones do not adhere as they are supposed to causing severe pain and debilitation. Responsible dog breeders will only breed their breeding dog specimens after they have received clearance for OFA, the Orthopedic Foundation for Animals. Diagnosis is obtained after reviewing hip x-rays and classifying the hips under the following categories: Excellent,Good, Fair, Borderline, Mild Dysplasia, Moderate Dysplasia or Severe Dysplasia.

Defeat Genetic disorders with Ayurveda

Genetic disorders are incurable or atleast considered difficult to cure. These ailments have roots in the chromosomes that contain blue prints of cellular functions. A chromosome is genetic material within the nucleus of a cell. Damage to the nucleus prevents the cell from behaving normally. A genetic disorder is an illness caused by abnormalities in genes or chromosomes. Genes are inherited as units, with parents dividing out their genes to their offspring. You can think of this process like mixing two hands of cards, shuffling them, and then dealing them out again. An egg then joins with a sperm to give a child with a new set of genes.

Genetic disorder damages small intestine - Celiac disease symptoms

Those suffering from Celiac disease cannot eat and digest the cake, pizza, chocolate chip cookies, and other stuffs that hold a type of protein known as gluten. When a person with Celiac disease consumes these foodstuffs, they suffer badly with various problems related to their immune system and digestion.

Gluten in common, referred to as a group of proteins that could be found in wheat, barley, rye, and grains. When he eats such food that contains gluten, their intestine suffers from severe damage. Grains are very common food that we eat almost everyday, making the gluten as the most frequently eating ingredient. When it comes about our digestive system, we must know the functions of it properly. In general, we are aware of the fact that the digestive system is the group of organs that helps us to digest whatever we eat. It absorbs the main nutrients from the food we eat, that our body requires to keep us healthy and grow. Read more >>

Genetic Disorder - Thalassemia

Thalassemia is a hereditary disease. It is an autosomal recessive blood disease. Autosomal recessive pattern means both copies of the gene in each cell have mutations. Thalassemia is also known as Mediterranean anemia, Jaksch anemia or Cooley\'s anemia. This is not a single disorder but a group of defects with similar clinical effects. A group of inherited anemia, in which there is a defect in alpha or beta chains of hemoglobin. The anemia affected to the alpha chains is known as alpha thalassemia and the anemia affected to the beta chains are called beta chains. Thalassemia major is to describe homozygote and Thalassemia minor to heterozygote. The defect results in reduced rate of synthesis of one of the globin chain that makeup hemoglobin. This causes the formation of abnormal hemoglobin molecules which causes anemia, a characteristic symptom of thalassemias. Thalassemia includes different types of anemia. The severity depends up on the number of genes it affected. In this disorder the patient is unable to produce red blood cells and the reduction has to be supplemented with the transfusion of red blood cells, every 2-3 weeks to make patient healthy and to survive.

Diseases and Disorders That Can Cause Hearing Loss

If you or someone you know is suffering from hearing loss for no apparent reason, it is a good idea to check the following disorders to see if your symptoms correlate with those caused by the disease.

Treacher Collins Syndrome (TCS). Also known as Mandibulofacial Dysostosis, among other things, TCS is a rare genetic disorder that causes obvious facial distortions and abnormalities. These can include deformed or even completely missing ears, a small lower jaw, and other eye and mouth misshapenness. This is due to hypoplasia, which is the underdevelopment of the craniofacial bones. Because of the ear formation anomalies that can happen with TCS, people with the disorder may also suffer from hearing loss. For people missing ears, bone conduction hearing aids can help.

The Role of Genetics in Attention Deficit Disorder

When asked to depict the function of Genetics when it comes to the signs of ADHD in adults you may get as many numerous answers as there are scientists answering the inquiry. Does genetics play a function in determining if a child will suffer from ADHD? The reply, so far, is that we truly cannot know for certain. Signs of ADHD don\'t follow a stern set of guidelines that can be mapped out with a cat scan or that can be exposed by a particular DNA strand. There are numerous variations of the disorder with more inattentiveness or more hyperactivity depending on the person and whilst the symptoms are alike there can be extreme variations of outcomes from patient to patient.

A study from the American Journal of Medical Genetics in 2009 followed more than 900 families from the largest genetic research of ADHD in adults, uncovering over 600,000 genetic markers and making the data public for researchers around the entire world to analyze. Whilst the study showed pretty clearly that 1 genetical marker may be associated with ADHD symptoms, the study suggests that many genes are additionally involved in those patients troubled from Attention Deficit Disorder and that every of these have individually smaller effects that lead to the patient\'s symptoms.

Information About Genetic Diseases

Genetic disorders or diseases are caused by mutations or abnormalities in genes. Genetic diseases are often heritable and can be occur due to a plethora of reasons, most of which are often unknown. Unfortunately we don\'t know ways to stop genetic disorders before giving birth to a child. In this article, I will give you information about different genetic diseases.

Common Genetic Disorders

Down syndrome

Down syndrome, Down\'s syndrome, or trisomy 21 is a chromosomal disorder caused by the presence of all or part of an extra 21st chromosome. Individuals with Down syndrome tend to have a lower than average cognitive ability, often ranging from mild to moderate developmental disabilities. Many of the common physical features of Down syndrome also appear in people with a standard set of chromosomes.
