REVEL developers Weiva Sieh, MD, PhD, left, and Joseph Rothstein, MS
Sequencing-based genetic tests are making personalized medicine a reality for patients who carry certain mutations for serious diseases, including breast and prostate cancer. Armed with information about the pathogenicity of such variants in their genome, these patients can now make proactive decisions about their health care early enough to increase the odds of success in preventing or treating disease.
But for each step forward in this new frontier of personalized medicine, physicians and scientists are stymied by their lack of knowledge about thousands of other rare variants in a patient’s genome that could also portend disease. For this reason, two researchers at the Icahn School of Medicine at Mount Sinai developed REVEL, a novel tool designed to make sense of these variants of unknown importance in order to help guide patient care and risk management and to facilitate research.
Developed by Weiva Sieh, MD, PhD, Associate Professor of Population Health Science and Policy, and Genetics and Genomic Sciences; and Joseph Rothstein, MS, an Instructor of Genetics and Genomic Sciences, and Population Health Science and Policy, REVEL is an acronym for Rare Exome Variant Ensemble Learner. The tool predicts the likelihood of whether a particular coding variant in a person’s genome is disease-causing or benign.
“REVEL is timely and significant because the number of rare variants discovered by sequencing studies is vast and growing and little is known regarding their function,” says Dr. Sieh. “Yet few pathogenicity prediction tools have targeted rare missense variants, leaving researchers and clinicians to struggle with their interpretation.” The ability to distinguish among the approximately 10,000 missense variants in each person’s genome that result in protein changes that could potentially be harmful also helps researchers set priorities for the variants they may wish to study further as new disease-causing genes. Identifying more of these variants would enable personalized medicine to realize its potential in helping more patients benefit from prevention and treatment regimens tailored to their individual disease risks.
Other tools that use different predictive features do exist, but they often do not agree with each other on the likelihood of pathogenicity. Dr. Sieh and Mr. Rothstein created REVEL as an ensemble method that uses machine learning to combine information from many of these other tools in order to generate a consensus score. REVEL incorporates 18 pathogenicity prediction scores from 13 tools, and it specializes in prioritizing the most clinically or functionally relevant variants among the sea of rare variants that are being discovered through next-generation sequencing.

Seven physicians who have distinguished themselves in medicine or biomedicine, or extraordinary service to The Mount Sinai Hospital, the Icahn School of Medicine at Mount Sinai, or its alumni, were honored with the 2017 Jacobi Medallion—one of Mount Sinai’s highest awards—on Thursday, March 16, at a special event held at The Plaza. Donald Bergman, MD, MSH ’77, President of the Mount Sinai Alumni Association, opened the evening’s events, and Sandra Masur, PhD, Chair of the Jacobi Medallion Award Committee, introduced the recipients.
Dennis S. Charney, MD, Anne and Joel Ehrenkranz Dean, Icahn School of Medicine at Mount Sinai, and President for Academic Affairs, Mount Sinai Health System, addressed nearly 325 alumni, donors, faculty, and staff at the award ceremony, including Kenneth L. Davis, MD, President and Chief Executive Officer, Mount Sinai Health System, an alumnus of the medical school class of 1973.
“We have invested in the development of intellectual property, patents, and novel partnerships with industry,” Dr. Charney told the audience. “Exciting discoveries have poured forth, including a new understanding of the role of the microbiome in Crohn’s and colitis diseases. We’ve identified genetic risk factors for Alzheimer’s, Parkinson’s, autism, and other mental illnesses, and developed new therapies for multiple myeloma, melanoma, depression, and avian flu, to name just a few.” These advances, he said, were a tribute to the generosity and support of Mount Sinai’s alumni and to the dedicated educators who carry out “Mount Sinai’s longstanding tradition of excellence.”

Mount Sinai Doctors and The Actors Fund recently opened The Samuel J. Friedman Health Center for the Performing Arts, a medical facility in a very “Broadway” location—upstairs from the Actors Fund headquarters at 729 Seventh Avenue and up the street from the Times Square TKTS booths.
The Center is open to the general public, but its services and flexible hours are targeted to people in entertainment and the performing arts. Staffed by Mount Sinai physicians, it offers primary care services, including wellness checkups, urgent sick visits, and health screenings, and is planning to add specialty services in fields like orthopedics and otolaryngology later this year. “This really is a collaboration; it’s like putting on a show,” the actor Brian Stokes Mitchell, Chairman of the Board of Trustees of the Actors Fund, said at the ribbon-cutting ceremony on Thursday, March 2.
Partly funded by a $1 million donation from the Gerald J. and Dorothy R. Friedman New York Foundation for Medical Research, the Center is a project special to the Friedman family, which has deep ties to both medicine and the arts. It is named for the late Samuel J. Friedman, a publicist who worked with performers Bette Davis and Gypsy Rose Lee—and who was the brother of the late Gerald J. Friedman, MD, founder of the Diabetes Institute at Mount Sinai Beth Israel that bears his name.
“Mount Sinai has a long history of providing primary and specialty care for the performing arts community, and we are proud to continue that legacy in our partnership with The Actors Fund,” says Evan L. Flatow, MD, President of Mount Sinai West.
As the Zika virus continues to spread rapidly across the globe, it might pose a particular risk to people previously infected with two related viruses, dengue and West Nile, researchers at the Icahn School of Medicine at Mount Sinai have found. Their study, published in the journal Science, may help explain the severe manifestations of Zika virus infection observed in specific populations, including those in South America.
