Research/Academic Interests
Jeffrey P. Gregg's research laboratory has been dedicated to understanding the genetic basis of
cancer using two fundamental biological processes, the genetic predisposition for cancer and
molecular alterations (changes in DNA, gene expression and protein) that occur in individual
tumors.
In searching for common genetic modifiers of cancer at the DNA level, Gregg has examined links
between polymorphisms in the methylenetetrahydrofolate reductase gene and prostate cancer. He
used innovative technology and informatics to study complex somatic changes in tumor formation,
understand the underlying biology of cancer, and define better predictors for prognosis and
responsiveness to clinical adjuvant modalities.
Dr. Gregg, an expert in microarray technology, has also moved into the neurosciences and research
on autism. He has taken a unique approach to studying autism that uses microarray technology to
perform gene expression studies of the entire genome of peripheral lymphocytes in order to
identify genes associated with autism.
In addition to these microarray studies, he is adapting microarray technology to identify gains and
losses (i.e., duplications and deletions) in the genome of children with autism.
