Research Program :
Laboratory research interest has recently focused on the mutational
events that are responsible for the X-linked disorder, hemophilia B.
In collaboration with Drs. Hans Chen and Arthur Thompson, the molecular
defects involving the factor IX gene have been shown to involve deletions,
insertions and single base pair changes. The specific mutations are
usually unique for each family and can be used for carrier detection
and prenatal diagnosis. The mutations that affect the factor IX locus
are being used as a model to address questions of mutation rate in male
and female gametes and mechanisms of recombination for X-linked genes.
Dr. Scott is a clinical biochemical geneticist and investigates the
molecular basis of human metabolic disorders. He supervises a clinic
committed to the diagnosis and management of children affected with
inborn errors of metabolism, and is responsible for the supervision
of a laboratory devoted to the accurate analysis of biological specimens
submitted for the chemical or molecular detection of genetic disease.
Diagnostic techniques in biochemical genetics using gas chromatography/mass
spectroscopy, high pressure liquid chromatography, and enzyme analyses
are available for training of post doctoral fellows. A molecular diagnostic
laboratory focusing on common disorders affecting children (fragile-X,
muscular dystrophy, cystic fibrosis, Prader-Willi/Angelman) is also
available for training. In collaboration with investigators at the Fred
Hutchinson Cancer Research Center, a clinical trial has been initiated
on the efficacy of gene therapy for patients with Gaucher disease. This
program uses isolated bone marrow stem cells that have been transfected
with retroviral vectors containing the normal b-glucocerebrosidase
gene.
Investigator: Dr. Scott is a Professor of Pediatrics, and an Associate
of the Center on Human Development and Disability.
