The hereditary cancer syndrome is caused by an inherited mutation in a gene called BAP1, researchers say.
The findings suggest that BAP1 mutations cause the disease in a small subset of patients with hereditary uveal melanoma and other cancers.
Uveal melanoma is a cancer of the eye involving the iris, ciliary body, or choroid, which are collectively known as the uvea. These tumors arise from the pigment cells, also known as melanocytes that reside within the uvea giving color to the eye. This is the most common type of eye tumor in adults.
The findings are reported in the Journal of Medical Genetics.
"We are describing a new cancer genetic syndrome that could affect how patients are treated," said first author Dr. Mohamed H. Abdel-Rahman, researcher at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute. "If we know that a patient has this particular gene mutation, we can be more proactive with increased cancer screenings to try to detect these other potential cancers when they are beginning to grow."
Study leader Dr. Frederick H. Davidorf, professor emeritus of ophthalmology at Ohio State University, explained that BAP1 seems to play an important role in regulating cell growth and proliferation, and that loss of the gene helps lead to cancer.
"If our results are verified, it would be good to monitor these patients to detect these cancers early when they are most treatable," said Davidorf, who treats ocular oncology patients at Ohio State along with researcher and physician Dr. Colleen Cebulla.
The study involved 53 unrelated uveal melanoma patients with high risk for hereditary cancer, along with additional family members of one of the study participants. Of the 53 patients in the study, researchers identified germline variants in BAP1 in three patients.
"We still don't know exactly the full pattern of cancers these patients are predisposed to, and more studies are needed," said Abdel-Rahman, also an assistant professor of ophthalmology and division of human genetics at Ohio State University College of Medicine.
"So far, we've identified about six families with this hereditary cancer syndrome. We are working with researchers at Nationwide Children's Hospital to develop a clinical test to screen for the BAP1 gene mutation," he said. "Families with this cancer syndrome should be screened for inherited mutations that increase their risk for developing several other cancers."
Other Ohio State researchers involved in the study include Robert Pilarski, James B. Massengill, Benjamin N. Christopher and Getachew Boru, along with Peter Hovland of the Colorado Retina Associates in Denver.
Funding from the Patti Blow Research Fund in Ophthalmology and the American Cancer Society supported this research.
The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute strives to create a cancer-free world by integrating scientific research with excellence in education and patient-centered care, a strategy that leads to better methods of prevention, detection and treatment. Ohio State is one of only 41 National Cancer Institute (NCI)-designated Comprehensive Cancer Centers and one of only seven centers funded by the NCI to conduct both phase I and phase II clinical trials. The NCI recently rated Ohio State's cancer program as "exceptional," the highest rating given by NCI survey teams. As the cancer program's 210-bed adult patient-care component, The James is a "Top Hospital" as named by the Leapfrog Group and one of the top 20 cancer hospitals in the nation as ranked by U.S. News & World Report.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
