Essays on Genetic Disorder

Description

The Rett syndrome is originally known as cerebroatrophic hyperammonemia. It is a rare genetic disorder which commonly affects women although there are cases where it could be found in male patients. It is considered as a postnatal neurological disorder which affects the grey matter of the brain. Rett syndrome is also considered as a progressive disorder which affects the development of the brain. It is also considered as one of the common cause of mental disorders among women. It occur about 1 in 10,000 births and it typically develops at age 6 to 18 months. The signs or ...

Abstract

Hemophilia is a genetic condition that is traceable in generations. The disease is usually linked to the excessive bleeding of the patient at a point where the blood vessel is damaged. A lot of research on the disease has been carried out trying to define the origin of the disease and offer extensive support to the solution of the condition. Over time, the disease has attracted extensive attention as the cases of the disease increase. It has not been easy to control the disease since the condition has been overwhelmingly disturbing to the patients as well as the family ...

Medical genetics is viewed as one of the ways to diagnose and manage any hereditary disorders. It encompasses various areas, such as physician’s clinical practice, activities in diagnostic laboratory, and even research to point out the possible causes of genetic disorders. This medical approach can be beneficial many people, as there could be new ways to predict any future diseases that may arise due to the disorders of the gene. It can also benefit the children when it comes to knowing the possibility of having medical issues based upon the tested genes of his or her parents. However, ...

Gene Typing Tay-Sachs

Tay-Sachs disease is an inherited metabolic disease of lysosomal lipid metabolism, and it is caused by the mutation of genes encoding the HEXB gene. It is a very severe genetic disorder which occurs in children in most cases and results in progressive destruction of the nervous system of the affected individual (Walker, 2007). The factors that cause the occurrence of the diseases is the absence of the hexosaminidase-A (HEX-A) enzyme that is very critical to have in the human genetic system. The lack of the HEX-A enzyme causes the accumulation of a fatty substance known as GM2 ganglioside in ...

Genes are the hereditary units that express proteins in a cell to carry out body metabolism and overall growth and survival. They are the functional units on DNA that is packages inside the nucleus within chromosomes. Humans consist of 23 pairs of chromosomes where 22 are autosomes and one is sex chromosome. These chromosomes have been studied to comprise of around 25,000 protein coding genes. There are continuous phenomenon of changes and aberrations occurring in bases and chromosomes that alter its composition and sequences. These changes or mutations can be harmful if it modifies the gene information as ...

What is Down syndrome?

Down syndrome also known as Trisomy 21 is a chromosomal condition where a person possesses extra genetic material that is: an extra complete or fractional duplicate of chromosome 21. It is one of the most common birth defects. It affects 1 in 800 to 1 in 1000 live born infants. Close to half of all affected children develop heart defects right from birth (Goldstein 71).

Causes

Down syndrome is typically caused by non-disjunction; when one of the three types of abnormal cell division involving chromosome 21 occurs. Non-disjunction occurs when a pair of chromosomes fails to detach during sperm or egg formation. After ...

Introduction

King Tutankhamun also known as King Tut or Tutankhamen was an Egyptian pharaoh who ruled between the period of 1336 and 1327 BC. He is believed to the 12th ruler of the 18th Dynasty of Egyptian history (Carter and Romer 2008). His precious mummy discovered in 1922, in the Valley of Kings by Howard Carter and George Herbert first brought king Tutankhamun to light.. It is the discovery of Tutankhamun’s mummy that first made Tutankhamun and his lineage a subject of public interest worldwide. A lot of facts have been uncovered about him ever since, and all these facts ...

In 1997, the public have been shocked about the announcement of the successful mammal cloning. Dolly, the sheep, is the first to be cloned by Ian Wilmut and his co-workers by the process of transferring nuclear genome (Brock 1). There are issues that arise from the public about the morality and ethics of the research method and objective. They are afraid of what should the next thing that could happen after this technological advancement. On the other side, the scientific world have been fascinated and rejoiced about the announcement of Wilmut. There are many scientists that are excited of ...

Down Syndrome is a genetic disorder. According to NSGC (para.1), the National Society of Genetic Counselors, the human body is made of cells whose nucleus have chromosomes that contain the DNA that carries traits. Each Nucleus normally contains 23 pairs of chromosomes; down syndrome occurs when an individual ends up with an excess of chromosome 21, full or partial. When this chromosomal abnormality due to the extra chromosome occurs, a child is born exhibiting traits characteristic of down syndrome. Many children are born with Down syndrome, since it the most common genetic disorder. Due to progress in medical technology and research, ...

Introduction

Most of us have faced moments when we were not able to concentrate on the work on hand. There were times when focusing on a task was a big challenge. However, for most of us this type of syndrome is not very common. However, for some people these types of behaviors are a day-to-day affair. For those people this type of syndrome is uncontrollable and persistent. If a person shows such signs then they may be a victim of attention deficit hypersensitivity syndrome. Attention Deficit Hypersensitivity Syndrome (ADHD) does not show any physical signs or cannot be detected using laboratory tests. The symptoms of ...

Introduction

Genes are the smallest functional units present in the human body, which controls the development and formation of the organism. These genes are present on the chromosomes as pair and are expressed when the body needs a certain protein or compound. However, at times, one or both the genes may be faulty due to mutations. This impaired gene causes the formation of a Genetic disorder. These genetic diseases were studied with the tools of biotechnology and thus developed the Gene Therapy technique (Sheridan 121). Gene therapy is a tool that uses biotechnological techniques to prevent diseases caused by defective genes. It ...

Argumentative Essay on Fertility Donation

- Introduction Assisted reproductive technologies (ART), also referred to as third party reproduction, are a wide range of technologies that are used to help people to get children. The technologies are used in various circumstances that make it impossible for the person to bear a child, for instance where either of the partners is infertile, in gay marriages, where a genetic disorder that may be passed on the offspring has been detected in one of the partners and other circumstances that will be specifically mentioned in this paper. The assisted reproductive technologies, while they have helped people who could not have ...

Genetic testing also known as DNA based test, involves direct examination of DNA molecules to test for genetic disorders and diseases (Gene testing, 2010). According to the Human Genome Project Information (2010), Genetic testing can be used for various reasons to include: - Identifying people who carry one copy of genes causing diseases such as Huntington’s disease. - Pre-symptomatic testing of adult onset diseases/disorders such as Huntington’s disease - Forensic testing and determining paternity. - Newborn screening and pre- natal testing. DNA stands for Deoxyribonucleic acid, and these are chemical Data bases ...
