Abstract

The lysosomal degradation of glucosylceramide requires the hydrolase, glucosylceramide-beta-glucosidase and a sphingolipid activator protein (Gaucher factor, SAP-2, saposin C). Genetic defects in either of these lysosomal proteins cause phenotypically similar disorders in man, the Gaucher disease. SAP-2 originates from a gene which generates a mRNA that codes for four homologous proteins. In a patient with an immunologically proven SAP-2 deficiency a G1154----T transversion (counted from A of the initiation codon ATG) was found in the mRNA of the SAP-2 precursor which results in the substitution of Phe for Cys385 in the mature SAP-2. The rest of the coding sequence remained entirely normal.
