Living with ASAH1-related sphingolipidosis

A group of genetic conditions caused by changes in the ASAH1 gene, including Farber disease.

Understanding ASAH1-related sphingolipidosis

ASAH1-related sphingolipidosis is a group of conditions caused by changes in the ASAH1 gene.

The group includes Farber disease and spinal muscular atrophy with progressive myoclonic epilepsy. The ASAH1 gene makes an enzyme in the lysosomes (cell recycling centers) that breaks down a fat called ceramide.
