Taking a Look in Tay-Sachs Disease

Main Point C: The similarities and differences between Tay-Sachs and Fragile X as wells as the similarities and differences between Alzheimer’s and Parkinson’s.

Lysosomes – Lysosomes act as the digestive system of the cell. They are found in all parts of the cell. There are very powerful enzymes within lysosomes.

There are no treatments or cures for Tay-Sachs disease; however, through palliative care,  treatment is used to keep the child comfortable. Palliative care often includes prescription medication to relieve symptoms, the use of feeding tubes, physical therapy, and respiratory care to avoid issues with the lungs and airways.

Since children lack the HEXA-A gene it causes progressive damage and eventually the nervous system will shut down because it can no longer produce vital neurons needed to function the nervous system and life. Beta-hexosamindinidase is located in the lysosomes, which are structures in cells that act as recycling centers and breaking down the toxic substance. Beta-hexosamidnidase role is toxic and fatty substances called GM2 ganglioside. If the gangliosides become overpowering or too much, can cause destruction of the neurons. The excessive storage of the gangliosides in lysosomes is another factor that causes Tay-Sachs. Tay-Sachs occurs usually when the individual lacks the protein hexosamindinidase A and defected and alterations on chromosome 15 (specifically 15q23-q24). More than 50 mutations having been discovered on chromosome 15 and HEXA-A enzyme. The mutation can vary as in deletion, insertion, and splitting in which each mutation alters the protein. The mutation and disorder cause a decrease in enzymes activity. The severity of the disorder depends on the degree of the enzyme activity and deficiency. For example, one mutation includes, the mutation includes a G-to-T substitution at the 3-inch end of intron 5, which makes a short mRNA. Then skipping exon 6 and the polypeptide lacking 34 amino acids. (Tanaka

It has come to my attention that you believe Tay-Sachs disease is less devastating than ALD. To make an assumption does not do you justice and I am here to inform you on each of these demyelinating diseases so you can understand why in fact Tay-Sachs disease is in fact more devastating than ALD

Tay Sachs Disease, or TSD, is a fatal genetic disorder that result in the degeneration of the nervous system. TSD is presented in three forms, those being classic infantile, juvenile and adult late-onset. The most commonly seen form of TSD is that of classic infantile Tay Sachs Disease. In the classic infantile form, infants generally experience their first symptoms by 6 months of age. Death of infants with TSD is typically by age 5. The symptoms that TSD infants will experience prior to death include: an onset of retardation, paralysis, dementia, blindness and reoccurring seizures. The absence of hexosaminidase-A, or what we will refer to as Hex-A, is the cause

Tay Sachs Disease is an inherited disease that results in slow destruction of the central nervous system and sensory systems, which is caused by a mutation resulting in a deficiency of a lysosomal enzyme. The missing enzyme, hexosaminidase A, functions in breaking down the fatty material ganglioside GM2, a chemical found in nerve tissue. Without this enzyme, lipids accumulate in the brain cells and destroy them, resulting in damaged nerve cells, neurological problems, and eventually leading to death several years after birth. The disease was first discovered by Waren Tay, a British ophthalmologist in 1881. Tay-Sachs disease is very rare in the general population and is relatively common among certain ethnic groups such as Eastern Europeans

effective at keeping movement within the joints possible and helps to relieve stiffness of the patients (“Tay-Sachs disease”, 2016). There are a few experimental treatments developing. The first is Tay-Sachs Gene Therapy, this treatment includes introducing genes into diseased cells to try and correcting the mutations such as lysosomal defects (Cachon-Gonzlez, et al., "226. Effective Gene Therapy in an Authentic Mouse Model of Tay-Sachs Related Diseases", 2006). Cross correction mechanism is the proposed mechanism of action.

Tay Sachs disease is a life threatening disease that is passed down through families. Anyone can be a carrier of Tay Sachs, but is not common in the general population. The disease is most common in the Jewish population. 1 in every 27 members is a carrier of the disease. Tay Sachs disease is a rare inherited disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord. The most common form of Tay Sachs disease becomes apparent in infancy. Infants with this disorder typically appear normal until the age of 3 to 6 months, when their development slows and muscles used for movement weaken (Genetics Home Reference, 2017).

Tay Sachs is a disease in the nervous system. It mainly occurs in infancy, and the infant can appear normal until ages 3-6 months when their muscles for movement weaken and development slows down. Affected infants with Tay Sachs disease loose motor skills such as sitting, crawling, and turning over, and in some cases develop an extreme startle reaction to loud noises. As this vigorous disease advances, children distressed can experience paralysis, intellectual disability, seizures, hearing and vision loss, and an eye abnormality called a "cherry-red spot." Most children afflicted usually only live into early stages of childhood.

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.

Tay-Sachs disease (TSD) is a fatal genetic disorder resulting in progressive destruction of the nervous system. Tay-Sachs is caused by the absence of a vital enzyme called hexosaminidase-A (Hex-A

Tay-Sachs disease is an autosomal recessive genetic disorder, which means it can be passed down parents’ genes and is located on a non-sex chromosome. The form ,ost discussed is known as infantile Tay-Sachs disease, the symptoms of which are the deterioration of mental and physical abilities, which starts affecting children at six months old and normally results in death by the age of four. It is caused by a genetic defect in a single gene with one defective copy of that gene inherited from each parent. The disease occurs when harmful quantities of gangliosides gather in the nerve cells of the brain, eventually leading to the premature death of those cells. The condition is

The members will be a physician, a geneticist, an ethicist, a lawyer and a nurse. The physician, who is a pediatrician, makes the diagnosis of Tay Sachs. The geneticist, another specialist, provides more specific and applicable information on Tay-Sachs, such as causes and risks, prevention, diagnosis and treatment. These two specialists formulate a plan of care, which a nurse will implement. The ethicist informs them about accepted moral values and the proper human conduct, behavior and decisions in dealing with Tay-Sachs. The lawyer or legal practitioner informs the involved parties about the current laws and court decisions concerning or affecting the management of genetic disorders, such as Tay-Sachs. And the nurse carries out the detailed instructions of the geneticist and pediatrician as well as incorporates the guidelines inputted by the lawyer.
