Here's why:
* Metabolic Waste Build-up: Tay-Sachs disease is a lysosomal storage disorder. This means that the body lacks a specific enzyme (hexosaminidase A) needed to break down a fatty substance called GM2 ganglioside. This substance then accumulates in the brain and spinal cord, leading to progressive neurological damage.
* Fatal: Tay-Sachs disease is a devastating condition that ultimately leads to death, usually within a few years of diagnosis.
Other lysosomal storage disorders can also cause a build-up of metabolic waste in the body, but they may have different symptoms and prognoses.
It's important to note: If you are concerned about a possible genetic disorder, you should consult with a medical professional for a proper diagnosis and advice.
