What organelle is hexosaminidase-A in?
Hexosaminidase-A is located in the lysosomes, which are membrane-bound organelles responsible for breaking down waste materials in the cell. It plays a critical role in the degradation of glycosphingolipids, particularly gangliosides, within the lysosomal compartment. Deficiency in hexosaminidase-A can lead to the accumulation of gangliosides and result in neurodegenerative diseases such as Tay-Sachs disease.
What are other names for tay sachs disease?
Tay-Sachs disease is abbreviated to TSD and is also known as GM2 gangliosidosis or Hexosaminidase A deficiency.
What is caused by a deficiency of the enzyme Beta hexosaminidase A?
A deficiency of the enzyme Beta hexosaminidase A leads to Tay-Sachs disease, a rare genetic disorder that results in the progressive destruction of nerve cells in the brain and spinal cord. Symptoms typically appear in infancy and include developmental delays, loss of motor skills, and eventually, blindness and seizures.
What does the gene that cause tay sachs normally do?
The gene that causes Tay-Sachs disease normally provides instructions for making an enzyme called hexosaminidase A. This enzyme helps break down a fatty substance called GM2 ganglioside. Mutations in this gene lead to a deficiency in hexosaminidase A, causing the buildup of GM2 ganglioside in cells, which leads to the symptoms of Tay-Sachs disease.
What part of the cell is defective in pompe's disease and Tay-Sachs disease?
In Pompe's disease, the defect lies in the lysosomal enzyme alpha-glucosidase, which leads to the accumulation of glycogen in lysosomes. In Tay-Sachs disease, the defect is in the enzyme hexosaminidase A, which leads to the accumulation of GM2 gangliosides in lysosomes.

What has the author Yongmin Hou written?
Yongmin Hou has written: 'The analysis of the [alpha]-active site of human hexosaminidase A'
Are there any other names for tay-sachs disease?
Tay–Sachs disease is also known as GM2 gangliosidosis or hexosaminidase A deficiency. Other names are: B variant GM2 gangliosidosis, GM2 gangliosidosis, type 1, Hexosaminidase alpha-subunit deficiency (variant B), Sphingolipidosis, Tay-Sachs and TSD.
Does tay-sachs go by any other name?
Yes! Tay-Sachs is also known as GM2 gangliosidosis or Hexosaminidase A deficiency.

Mutations in this gene lead to a deficiency in hexosaminidase A, causing the buildup of GM2 ganglioside in cells, which leads to the symptoms of Tay-Sachs disease.
What is the main cause of tay sachs disease?
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).
What is the test for Sandhoff disease?
Because Sandhoff disease and Tay-Sachs disease have similar clinical symptoms, distinguishing them requires biochemical analysis. This involves a test to measure enzyme activity of the two hexosaminidase enzymes.
What enzyme deficiency causes disease?
Tay-Sachs disease (TSD) is a fatal condition caused by a deficiency of the enzyme hexosaminidase A (Hex-A).
What prevention methods are there to avoid Tay-Sachs disease?
Prevention involves identifying carriers of the disease and providing them with appropriate information concerning the chance of their offspring having Tay-Sachs disease. When the levels of hexosaminidase A are half the normal level.
Tay-Sachs is a genetic disorder characterized by a deterioration of the?
chromosome 15 it causes the build up of a chemical called gangliosides because the defect causes the body to lack production of the protein hexosaminidase which breaks down the chemical.
