Ashkenazi's Beta-Hemosaminidase Disease

Huntington's disease is an inherited neurodegenerative disorder. It is passed on to children from one or both parents (though two parents with Huntington's is extraordinarily rare) in an autosomal dominant manner. This is different from autosomal recessive disorder, which requires two altered genes (one from each parent) to inherit the disorder.

There are many diseases in the world that can have severe negative impacts on a person and their family. Many neurodegenerative diseases are caused by genetic mutations. This essay will be discussing the similarities and differences between the diseases of Tay-Sachs, Alzheimer’s, Parkinson’s and Fragile X as well as their symptoms, treatments and intervention strategy’s.

Tay Sachs is an incurable genetic disease that affects the central nervous system. It is a rare disorder that occurs chiefly in infants and children, especially those of the Jewish heritage. It is characterized by a red spot in the retina, paralysis, gradual blindness, and loss of muscle movement.

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.

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.

These include motor neuron disease, corticobasal syndrome, progressive supranuclear palsy and FTDP-17 (FTD with parkinsonism linked to chromosome 17).

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

This disease is genetically inherited and is a dominant characteristic, therefore unfortunately the offspring of a victim has 50% chance of inheriting the disease.

In conclusion, Tay Sachs Disease is an auto recessive disorder that can only be inherited by a child if both of their parents are carriers of the trait. The likelihood of a pregnancy resulting in an affected child is one in four. In addition to how the gene is transferred via parents, there has also been research concluding that there is a correlation among those carrying the gene or affected by the gene and their ancestry. TSD is considered to be a Jewish disease due to the high number of incidences of TSD occurring in the Jewish

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

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).

Well what causes Tay Sachs disease is that there’s something wrong with there fifteenth chromosome with this problem your body has trouble making the protein hexosaminidase A, since your body doesn’t make that anymore gangliosides build up and eventually will kill brain cells. In order for your child to get this disease the defective gene has to be passed down from each parent so that would mean that Tay Sachs disease is a heredity disease. If the defective gene just gets passed down from one parent it means that the child is a carrier of Tay sachs disease, in which this means that if this child marries someone who is also a carrier of Tay Sachs disease that means that there child will absolutely have this disease

The genetic mutations that cause this disease are more commonly found in the Ashkenazi people with a Jewish heritage than those with other backgrounds. French-Canadian communities of Quebec, the Old Order amish community in Pennsylvania, and the Cajun population of Louisiana, are more responsible for the mutation for this disease. The HEXA has been discovered for the cause of Tay Sachs. The gene provides for making part of an enzyme, which is cause, "beta-hexosaminidase A", which plays an important role in the spinal cord and brain. Disruptions in the HEXA gene messes with the activity of beta-hexosaminidase A, and then prevents the enzyme from breaking down GM2 ganglioside. This results the the substance accumulating to toxic levels in the neurons in the brain and spinal cord. Continuous damage caused by the build up of GM2-ganglioside leads to the destruction of the neurons and thus causes the signs and symptoms of Tay-Sachs

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.
