Harvard Medical School
David Corey, PhD, is the Bertarelli Professor of Translational Medical Science, Blavatnik Institute of Neurobiology, Harvard Medical School. After years of studying the role of protocadherin 15, the Usher 1F gene, in hearing, he decided to pursue research on treating the vision loss of Usher 1F after attending Usher 1F Collaborative's May 2017 researchers symposium. Dr. Corey is working on three approaches to gene therapy, mini genes, split genes, and gene editing. He has begun testing of mini genes for efficacy on our zebrafish. We are very grateful to the Bertarelli Foundation for providing a substantial amounting of funding for Dr. Corey's Usher 1F work.

University of Oregon Institute of Neuroscience
Monte Westerfield, PhD, is at the Institute of Neuroscience and Department of Biology at the University of Oregon. His research is focused on Usher Syndrome with particular expertise in creating zebrafish models of Usher Syndrome mutations. Usher 1F Collaborative has funded the creation of a zebrafish model of the Usher Syndrome Type 1F R245X mutation that is carried by ~2% of those of Ashkenazi Jewish descent. Dr. Westerfield and his team, including Jennifer Phillips, Ph.D., are now beginning testing of drugs on our zebrafish that have the potential to halt or slow the progression of vision loss.

University of Maryland
Zubair Ahmed, PhD, at the University of Maryland, has developed a mouse model of the most prevalent Usher 1F mutation that he is now using to test potential gene therapies and, in collaboration with Dr. Westerfield, potential drug therapies. He is also working to develop a mini gene for gene replacment for Usher 1F.

University of Pittsburgh
Leah Byrne, PhD, at the University of Pittsburgh is developing a split gene dual vector system for gene replacement. Her unique approach increases the efficiency of viral vector co-infection, increasing efficacy of large gene expression. Once complete, Dr. Ahmed will test her vectors for efficacy on our mouse.

University of Iowa, Institute for Vision Research
Edwin Stone, MD, PhD, who is working to develop a cure for Usher 1F along with other types of retinitis pigmentosa at his lab at the University of Iowa, is working to halt further retinal degeneration from Usher 1F through gene replacement and to repair damage that has already occurred through replacement of damaged retinal photoreceptor cells with new cells made from the patient’s own skin cells, with a goal of a clinical trial once safety and efficacy are determined.

University of Western Australia
Livia Carvalho, PhD, at the University of Western Australia, is collaborating with Dr. Ahmed to develop gene replacement therapy for Usher 1F. She has developed a dual vector gene replacement therapy, which Dr. Ahmed is testing for efficacy on our mouse.

Centre for Eye Research Australia
Alex Hewitt, MBBS, PhD, is a Principal Research Fellow at the Menzies Institute for Medical Research and the School of Medicine at the University of Tasmania, as well as Principal Investigator at the Centre for Eye Research Australia. He is also a practicing ophthalmologist. Working with our partner family in Melbourne, Australia, Dr. Hewitt obtained a grant from the Australian government for his Usher 1F research and, using this money, is working on gene editing to effectively treat the vision loss of Usher 1F.

University of Toronto
Vincent Tropepe, PhD, received a two-year grant from Fighting Blindness Canada for his project Function of Usher Syndrome protein PCDH15 in photoreceptor maintenance. Dr. Tropepe will use a zebrafish model to study why and how mutations in the PCDH15b gene cause photoreceptor cell death and if gene therapy can help restore vision.
