Description of Clinical Expertise

Dr. O’Brien cares for patients at the Scheie Eye Institute. She specializes in the treatment of ocular tumors, including retinoblastoma, ocular melanoma, conjunctival malignancies, ocular metastases, and ocular and CNS lymphoma.

Description of Research Expertise

Dr. Joan O’Brien has extensive expertise in the study of the genetics of ocular diseases including retinoblastoma, melanoma and glaucoma. Dr. O’Brien’s laboratory has identified numerous unique pathogenic variants in the retinoblastoma gene (RB1). This testing has allowed retinoblastoma therapy to be directed according to underlying genetic risk, and is offered nationwide at no charge to patients through NEI’s eyeGENE™ initiative. Dr. O’Brien directs a research laboratory with next generation sequencing and high-throughput, automated Sanger sequencing capabilities, which focuses on translational genetics research with an emphasis on molecular sub-classification and endophenotyping of ocular disease. Currently, Dr. O’Brien is the primary investigator on an $11.25 million 5-year Primary Open Angle African American Glaucoma Genetics (POAAGG) study.

Clinical Trials
Dr. O’Brien has 15 years of National Cancer Institute funded leadership roles in clinical trials and phenotype validation for all retinoblastoma studies administered through the Children’s Oncology Group (COG). Over the past five years, in collaboration with colleagues at UCSF, the group has discovered and characterized two novel oncogenes (GNAQ, Nature 2009 and GNA11, NEJM 2010) which regulate the MAP kinase pathway. This has allowed Dr. O’Brien’s uveal melanoma patients to have personalized and targeted therapy with MEK inhibitors, providing prolongation of life for these patients with widely metastatic melanoma.
