A mutation of the HEX A gene of chromosome 15 causes Tay-Sachs disease. As a result, the protein hexosaminidase A is not formed properly and GM2 ganglioside, the lipid normally broken down by hexosaminidase A, accumulates to toxic levels (especially in the brain).
They are sufficated by fatty acids that are usually broken down by enzymes, but tay-sachs prevents the production of these enzymes
Tay-Sachs is caused by a mutation in the gene encoding the enzyme Hexosaminidase A.
The main cause of Tay-Sachs Disease is a genetic defect or mutation that is usually passed down from parent to child. This defect is located in the HEXA gene in the 15th chromosome.
Tay-Sachs disease is a human genetic disorder which results in the accumulation of cells due to the clogging caused by undigested lipids. The organelle involved in this disease is the lysosome.
if someone is a Heterozygous carrier of Tay-Sachs they would have to be Tt. Because TT is Homozygous.
its inherited from family member to family member
Lysosomes are responsible for digesting worn out organelles. If there was not a lysosome, then excess organelles would not be discarded. Tay-Sachs disease is caused by malfunction of lysosomes or one of their digestive proteins.
Tay–Sachs disease is caused by a genetic mutation in the HEXA gene on (human) chromosome 15. It is a rare autosomal recessive genetic disorder. And not sex-linked.it causes a progressive deterioration of nerve cells and of mental and physical abilities that begins around six months of age and usually results in death by the age of four. Two Tay–Sachs alleles are required for an individual to exhibit symptoms of the disease. This means that both parents must be carriers.
Tay-Sachs disease is a human genetic disorder.
what effect does Tay-sachs disease have on the body?

Multiple mutations are responsible for Tay Sachs Disease. For example, Tay Sachs in the french Canadian population may be due to a different mutation then people of eastern European Jewish descent with Tay Sachs. any mutation that causes the absence of the enzyme Hexosamindase (Hex-A) is a mutation that can cause a Tay Sachs genotype/phenotype within an individual
A person with tay sachs can live a healthy life but still battles the many limitations of Tay sachs disease. Depending on the type of tay sachs, Classic, Juvenile onset, and Late Onset depends how healthy a life a person with tay sachs disease.
About 16 cases of Tay-Sachs disease are diagnosed each year.
tay-sachs disease
There is no evidence that shows that tay-sachs is a sex-linked trait.

''Tay-Sachs'' was named after Warren Tay, an ophthalmologist who discovered the occurring red spot in the retina in 1881, and Bernard Sachs, who described the cellular changes related to this disease in 1887.
Tay-Sachs disease is abbreviated to TSD and is also known as GM2 gangliosidosis or Hexosaminidase A deficiency.
