Stephen Dlouhy, Ph.D.

Associate Research Professor in Medical & Molecular Genetics

Associate Director of Indiana University Molecular Genetics Diagnostic Laboratory

Laboratory Director of the DNA and Cell Repository and of the National Cell Repository for Alzheimer Disease

  • B.S. from Hiram College (Ohio)
  • Ph.D. from Indiana University (Bloomington)



Dr. Dlouhy has been a member of the Medical and Molecular Genetics faculty since 1987. He also has an appointment in Pathology and Laboratory Medicine and is a member of the Basic Science Component Committee of the School of Medicine.

His research interests cover a broad spectrum, including inherited diseases of humans and mice and cancer. He has been involved with the genetic mapping of the genes for a number of human disease including Pelizaeus-Merzbacher disease and Gerstmann-Straussler Scheinker disease as well as studies of the mouse genes for androgen binding proteins (ABPs) and the weaver and purkinje cell degeneration neurologic mutant mouse models. Studies of Pelizaeus-Merzbacher disease, a disorder of myelin in
the brain, included the identification of many of the first disease-causing mutations known worldwide. For mouse ABP, what began as a study of a sex-influenced salivary protein polymorphism, have
evolved to studies of a rapidly involving gene duplication system that may be associated with mate recognition and mouse subspeciation.  Much of his recent research effort comprises biospecimen (e.g., DNA and cell) repository activities for a number of neurologic disorders including Alzheimer disease and Parkinson disease.

Dr. Dlouhy is engaged in many teaching activities that include graduate (PhD and MS) students as well as medical students at both the departmental and school of medicine levels in Indianapolis and elsewhere in the state.
