Analysis of a splice-site mutation in the sap-precursor gene of a patient with metachromatic leukodystrophy

Sphingolipid activator proteins (SAPs) are small, nonenzymatic glycoproteins required for the lysosomal degradation of various sphingolipids with a short oligosaccharide chain by their exohydrolases. Four of the five known activator proteins (sap-A-sap-D), also called "saposins," are deriv...
