Analysis Of Tay-Sachs Disease

Description Tay-Sachs disease, (also known as GM2 gangliosidosis or hexosaminidase A deficiency), is a fatal autosomal recessive genetic disorder caused by insufficient activity of the enzyme beta-hexosaminidase A. It is very rare, found more prevalently among certain populations, like those with Eastern European, (Ashkenazi Jewish) heritage (Bethesda, 2014), and usually results in death by the age of four. The purpose of this essay is to illustrate the pathology and inheritance patterns of this genetic disorder, and provide the molecular base, prognosis, and possible treatments.

In biology, we learn a lot of information that we can use later on in life, no matter what field of study we go into. During this course, we learned about biochemistry, metabolic processes, homeostasis, molecular genetics and population dynamics. Throughout the learning process, we’ve had many questions or INTUS,

In order to review their inherited genetic risks and help them understand and provide counseling according to their specific needs the genetic counselor should know the Trosacks ' have already established that their unborn child has Tay Sachs disease and based on those needs they should be provided with appropriate guidance and counseling as they progress through their pregnancy. The discussion should include what causes genetic disorders, and what that means to the Trosack couple specifically, including dominant, recessive and x-linked disorders. However, recessive disorders should be fully discussed in this case. Another topic to include in the discussion are what genes and chromosomes are, and the relation to Tay Sachs disease.

Tay-Sachs disease is a rare genetic disorder that destroys the nerves of the brain and spinal cord (the neurons). Tay-Sachs is usually discovered during infancy, the child appears to be on track and developing normal until the first signs of symptoms become apparent. The children typically do not live past the age of 5 due to many symptoms of the disorder/disease. However there have been individuals with Adult Tay-Sachs Disease (ATSD) and Late Onset Tay-Sachs disease (LOTS) in which they develop mild symptoms later on and worsen throughout the years. The symptoms include: loss of motor skills or muscle movement, vision and hearing loss, intellectual disabilities and dementia, and even can cause paralysis. The most common way to notice a child

Tay Sachs is a genetic disorder that occurs when there is a missing enzyme in the body. This causes a buildup of fatty substances in the nervous system (Gale). Beta-Hemosaminidase, or HexA, is the missing enzyme that causes the various nerve disorders that happen within Tay Sachs (NTSAD). This disease is inherited in a few different areas of the world, but it is most commonly

Tay-Sachs disease is a rare genetic disorder. Nathan Harney was only 10 months old when he was diagnosed with this fatal disease. At an early age, he started to lose his skills and had consistent seizures. He couldn’t walk, sit, or stand on his own. During a careful eye examination, Nathan’s doctor found a cherry red spot in his eye which led him to the conclusion that he suffered from Tay-Sachs. Later, after he had genetic testing, Nathan was officially diagnosed with the genetic disorder Tay-Sachs. Sadly, Nathan passed away on June 18, 2015 at the age of four (Aaron and Kathryn Harney, 2011).

Imagine giving birth to a beautiful seemingly healthy baby, the doctor wiping him or her off and handing it to you. Two days later, the hospital discharges you, and you begin to spend the next 3 months adjusting your new baby to your home. Towards the 4 month mark you realize some serious symptoms that are hard to ignore such as the inability to grow beyond his or her small figure., inability to hold something like a spoon or even your finger,and lastly lack of eye contact. Scary as this scenario may seem, at least 16 babies are diagnosed with Tay-Sachs disease in United States every year. Unfortunately, the diagnosed cases are only found in toddlers because, children with this disease only survive to the age of 5 years of age.

Tay-Sachs disease is a genetic disorder which results in progressive destruction of the nervous system. Children are the most common victims of the disease. In the general population, Tay-Sachs itself is rare. Tay-Sachs disease is most commonly found in people of east and central European Jewish descent, French-Canadian communities of Quebec, Cajun population of Louisiana, and the Amish. Mutations in the HEXA gene are the cause of this disease. This can happen in Prophase one of Meiosis due to the crossing of the sister chromatids in tetrad form may have mutated the chromosome encoding all the info for the Hexa gene. The HEXA gene gives instructions to make part of an enzyme called beta-hexosaminidase A. Alterations in the HEXA gene may damage

Tay-Sachs sickness is an entangled and uncommon malady that happens when there is transformation in the DNA. This change does not permit the body to create 'Hex-A', which is basic to separating greasy mixes. Without this chemical, cerebrum and nerve harm can happen. Tragically this ailment has no treatment arrange and normally by 10 months of age, the youngster may encounter visual deficiency, seizures and be formatively postponed. The visualization is tragic: the kid will once in a while live past 5 years of age. The reason the youngster has this malady is on account of it is acquired. Either one or both of the folks are a transporter of this genotype that when communicated in posterity brings about Tay-Sachs. In the event that both folks

Tay Sach’s Disease The body is a very diverse and complex system. Tay-Sachs disease can be a very scary but rare illness. Tay-Sach’s is a genetic disease which causes destruction to vital body systems, such as the brain and spinal cord. The invisible disease at first, begins within the fetus

Tay Sachs Disease is an inherited disorder that kills nerve cells in the brain, and also in the spinal cord. A couple of things that could cause this mutation is a missing enzyme. This is an enzyme called ganglioside, that is a fatty substance. Another reason why tay sachs could appear is a change in chromosomes. This is chromosome number 15. The gene is the HEXA gene, or hexosaminidase A. This is a recessive disorder that you can only inherit if both parents have tay sachs. Some symptoms to know if you have this disease is weakened muscles, startling of loud noises, seizures, hearing loss, blindness, and paralysis. If you’re an infant and you have tay sachs disease, you will start to gain abilities, like crawling, but then start to lose them.

an affected gene, and a normal gene, and being a disease carrier like their parents. Scientists

Tay Sachs is a inherited and rare genetic disorder named after the two scientists that discover significant aspects of the disease. Their names are Warren Tay and Bernard Sachs. Warren Tay was a ophthalmologist who discovered the cherry red spot on the retina of the eye. Whereas, Bernard Sachs, a neurologist, discovered the cellular changes of the disorder (National Tay Sachs & Allied Disease Association, 2015). Tay Sachs varies and the most common being in infants. What is Tay Sachs disease? Tay Sachs is a inherited genetic disorder where both parents carry the gene and pass it on to their child.

Doctors have an important role in honor the patient’s autonomy by let them make their own decision in rather or not to have the embryos screen out for Tay-Sachs disease prior to fertilization. However, in this specific case we should also take in consideration the child’s best interest. The parents have already lost two children for the disease. As health care professionals we know that the couple still have a chance to produce an affected child since both of them are carriers. Therefore, we decided to do the Tay-Sachs PGD screening anyway, implant the healthy embryos and not disclose the fact that PGD was performed. In doing so the parents will have a chance to bear a healthy child who will have higher chance to have the best life possible.

A concept that supports the foregoing claim is the fact that genetic engineering in humans can help diminish and forestall congenital conditions. Moreover, many illnesses give individuals the demand to receive organ transplants; with organ transplants, their well-being would then be reimposed. Over one hundred and sixty thousand individuals in
