Overview

The main focus of my work is the investigation of the complex series of events at the cellular and tissue level that are at play in the evolution and of genetic disease. It is hoped that an understanding of disease at this level will result in the development of specific forms of therapy for rare genetic disease. My group has chosen to focus on a series of devastating progressive disorders termed lysosomal storage diseases.

Research

Clinical trial of BH4 for the treatment of classical PKU
It has now been suggested that small molecules can act as chemical chaperones for misfolded proteins that are caused by point mutations of genes. PKU is an inborn error of metabolism that is currently treated by very restrictive diet. In vitro studies have shown that BH4 can stabilize mutant PAH enzyme and lead to greater tolerance of PHE in the diet.

Proteomic approach to the identification of biomarkers of MPS disease
This project involves the identification, through serum proteomic studies, markers of disease severity and responsiveness. Markers will initially be identified in a murine model and subsequently validated in human samples.

Clinical trial of recombinant iduronidase in the treatment of MPSI
Clinical trial of recombinant iduronidase in the treatment of MPSI. This is a complex multicenter multinational clinical trial of the use of iduronidase for the treatment of the genetic disease MPS I.
