Extract of sample "Genetic diseases"

Key words: Genetic Disease, Mutations, Genes, Chromosomes, Medical Practitioners and multifactorial Genetic diseases Genetic diseases are disorders, which emanate from an individual’s genes or chromosomes abnormalities (Chantal & Farndon 544). Mainly, these abnormalities may range from a small mutation in a lone gene to either addition or substation of the entire set of chromosomes (Chantal & Farndon 545). People experiencing genetic diseases normally inherit them from their parents, though current studies have also cited one’s environment as one of the key contributing factor. Genetic diseases have two modes of inheritances, which include single gene and multifactorial inheritance (Chantal & Farndon 548). The latter mode of inheritance entails involvement of environmental factors besides multiple genes’ alterations in an individual’s body. For illustration, different genes that cause breast cancer where researchers have unveiled the presence of 6, 11, 13, 14, 15, 17, and 22 chromosomes besides environmental factors (Doak 10). Other multifactorial inheritance disorders include diabetes, obesity, cancer and arthritis (Doak 29). Single gene inheritance mainly emanates from mutation changes, which take place in the DNA sequence (Doak 10).
Presently, there are no effective methods meant for the treatment of many genetic diseases affecting humanity globally, though medical practitioners can advocate for various prevention methods (Doak 29). This is due to their diverse complexities once they reach at an advanced stage. For example, breast cancer and diabetes where after they have reached at advanced stages, medical practitioners normally result to the application of their respective management practices. This is to length the patient’s lifespan, and it entails occasional gene therapies coupled with doctors advising relatives to offer the ailing person both the necessary material and moral assistance (Chantal & Farndon 550). Most of the gene therapies advocated by medical practitioners; their core purpose entails alleviating the patients’ severe pain. This is a short-term resolution meant to give patients the necessary comfort while still living.

Genetic testing/Genetic Screening

...makers, but also by every other human on the planet. Prenatal genetic testing Prenatal genetic testing and screening is performed to establish whether the fetus has any chromosomal abnormalities and whether or not there is a chance of developing a genetic disease later on. Parents can make well informed decisions on whether they wish to continue with the pregnancy or not. It involves harvesting of fetal tissue to analyze DNA for prediction of a disease risk or genetic abnormalities. Amniocentesis and Chorionic Villous Sampling are techniques through which fetal tissue is harvested for genetic testing. Amniocentesis...

...within the particular system. Our Cardiovascular system is one of the systems that are very important to paying close attention to what we are feeling. Our cardiovascular system is also known as the circulatory system. Our heart is within the system, which is responsible for pumping the blood throughout our bodies. The heart is a muscle that is about the size of one's fist. If the heart is not functioning properly then there will be problems with the other systems within the body. There are multiple problems that can occur with the heart. Some can be genetic and present at birth while other conditions can occur as we live from day to day. Carotid Artery disease is one of the heart...

Role of Genetic Variations in Human Diseases

...Role of Genetic Variations in Human Diseases: Past, Present, Future Introduction It is now a reality that the vast majority of the human genome hasbeen sequenced in the laboratory; however, this has been possible due to numerous conceptual and technological advances in the area of genetics and related technologies. This had been a process of evolution where over time scientists were able to elucidate the DNA double-helix structure, discover the restriction enzymes, and eventually the polymerase chain reaction (PCR). All these led to the development and automatization of DNA sequencing leading to generation of physical and genetic maps by the well discussed Human Genome...

In the United States of America malaria ceased being an endemic disease in 1947, and cases of malaria are few, mostly resulting from traveling to regions of the world, where malaria is endemic and neglecting to take the required prevention...

Genetic and Non-genetic diseases of the liver

...Genetic and Non-Genetic Diseases of the Liver Alcoholic liver disease is an acquired pathological condition of the liver which occurs due to consumption of alcohol. The pathological condition is major concern in the developed world owing to the increased consumption of alcohol by the people. This condition was alone responsible for the 44 percent of the deaths associated with liver disease occurring in the United States in the year 2003 (McCullough et al 2010). Alcoholic liver disease is a matter of concern owing to the fact that 10 million people residing in the United States are alcohol consumers (Kumar et al 2005). It is because of...

Multidisciplinary Approach on Genetic Diseases: Tay-Sachs Disease

...Multidisciplinary Approach on Genetic Diseases: Tay-Sachs Disease I. Nature of Tay-Sachs Disease Tay-Sach Disease is a condition in which the neurons progressively degenerate. Fatty substances abnormally accumulate in neurons. Motor and sensory functions are thus affected by this disease. Its familial nature is demonstrated by the fact that this condition is common among the Eastern European Ashkenazi Jews (http://www.ninds.nih.gov/disorders/taysachs/taysachs.htm, 2007). A. Etiology Genetic Mutations and Enzyme Defects Development of Tay-Sachs Disease is attributed to mutations on the HEXA gene,...

The use of gene therapy to treat genetic diseases

...Treatment of Genetic Diseases through Gene Therapy 09-02-12 Treatment of Genetic Diseases through Gene Therapy Inheritance of Sickle Cell Anemia and Hemophilia: In the United States of America, the most common type of inherited blood disorder is Sickle cell anemia. In accordance with the latest report of National Institutes of Health there are an estimated 80,000 cases of sickle cell anemia in the United States alone. (JONES 2008). The beta globin gene responsible for sickle cell anemia passes on from one generation to another. The genetic pattern through which sickle cell anemia is inherited is not only complex but is quite mysterious as well. In each...

...INTRODUCTION All life forms bear genetic material, chains of deoxyribonucleic acid (DNA) that for their characteristics, including biological sex. Each characteristic has two or more traits, and for organisms that undergo sexual fertilization, having one over the other depends on several factors. During fertilization, the combination of genes from the ovum and sperm cell (heterogametes) should be the first determinant of trait. For humans, the heterogametic XX and XY, each letter corresponding to the gene coming from a parent, is the definitive determinant of biological sex, and is the code for female and male trait, respectively. The effects of other processes, such as genetic imprinting, are important...

According to a survey carried out by The Department of ecology, The Royal Veterinary and Agricultural University, the prevalence of Lyme disease in Denmark is approximately 4,98% (Matthews, 2012). The average number of infected nymphs during the assessment was approximately 3.0 per 100 m2 (Matthews, 2012). In addition, there was a correlation between the number of infected nymphs and the distribution in the number of Lyme...

...Genetic Experiments Genetic Experiments Understanding the genetic make-up of every individual is essential from the earlier stagesof life since a great number of human diseases are as a result of genetic disorders ranging from inheritance to acquired types. Therefore, identifying these disorders helps restraint instances of diseases like cancer, strokes among others. Genetic engineering is carried out to identify traits to identify both the phenotypic and genotypic compositions through screening. Moreover, causes of different kinds of diseases and even possible cures to the diseases are...
