The list includes most sphingolipidoses (ASAH1, GBA, GLB1, HEXA, HEXB, GM2A, PSAP, SMPD1), MPS (IDUA, SGSH, NAGLU, HGSNAT, GNS, ARSB, GUSB) and mucolipidoses (GNPTAB, GNPTG), as well as glycoproteinoses (MAN2B1, FUCA1, NEU1, CTSA), lipid storage diseases (LIPA), post‐translational modification defects (SUMF1), and lysosomal integral protein disorders (LAMP2, NPC1, NPC2, SCARB2, SLC17A5). This evidence concerns the gene PSAP and Lipid storage disease.
