WebAug 7, 2024 · Sandhoff disease is a rare lysosomal storage disease. It causes the destruction of nerve cells (neurodegeneration). This leads to problems with thinking and moving. Sandhoff disease is caused by harmful changes in the HEXB gene. Harmful changes in this gene cause decreased amounts of two enzymes in the recycling centers … WebThe symptoms of lysosomal storage diseases vary depending on the particular disorder and other variables such as the age of onset, and can be mild to severe. They can include developmental delay, movement disorders, seizures, dementia, deafness, and/or blindness.
