Living with Gangliosidosis

A group of rare inherited conditions where fat-like substances build up in the cell parts that break down materials, affecting the nervous system.

Understanding Gangliosidosis

Gangliosidosis is a rare group of diseases that affect lysosomes, the parts of cells that break down materials.

In these diseases, gangliosides, a fat-like substance, build up inside lysosomes. The cause is a problem with enzymes or helper proteins that normally break gangliosides down. They are grouped by which ganglioside builds up.
