title: JCL Roundtable: enzyme replacement therapy for lipid storage disorders.
abstract: There are several inherited disorders that involve abnormal storage of lipids in tissues leading to severe compromise of organs. Sadly, these are often accompanied by lifelong morbidity and early mortality. Disorders such as Gaucher, Fabry, and lysosomal acid lipase deficiencies (Wolman and cholesteryl ester storage diseases) have been known for many years, and provide a difficult and frustrating set of problems for patients, their families, and their physicians. With recombinant methods of protein synthesis, it is now possible to literally replace the defective enzymes that underlie the basic pathophysiology of many such disorders. The delivery of these enzymes into the affected cells is possible because of their location in the lysosomes where the natural degradation of their lipid substrates occurs. I have asked 2 well-known investigators to join us for this Roundtable. These are professors who have been involved with the research that has made this type of therapy possible and who have participated in the clinical trials that demonstrated the value of enzyme replacement therapy. They are Dr. Robert Desnick, dean of Genetic and Genomic Medicine and professor and chairman emeritus of the Department of Genetics and Genomic Sciences at the Icahn School of Medicine at Mount Sinai in New York City, and Dr. Gregory Grabowski, professor of Microbiology, Biochemistry, and Pediatrics, at the University of Cincinnati College of Medicine. Dr. Grabowski recently retired from that school to become the chief science officer of Synageva, a company involved in producing enzymes for this type of therapy.
