Multigene Panel Testing for Hereditary Cancer Risk
Historically, an understanding of a patient and/or their family’s cancer risk and predisposition was based in large part on patient pedigree or family history, histology, and age at diagnosis. However, since the completion of the Human Genome Project, advances in technology have moved from pedigree to single-gene testing to multigene testing and next-generation sequencing. Advanced practitioner...
متن کاملTesting for Hereditary Risk of Ovarian Cancer.
BACKGROUND: Approximately one out of every 10 ovarian cancers is caused by inherited mutations in identified genes. The characterization of hereditary ovarian cancer as an autosomal dominant disorder of specific gene mutations is more specific and useful than descriptive clinical syndromes such as "Lynch II," "site-specific ovarian cancer," or "breast-ovarian cancer." METHODS: The author review...
متن کاملUnderstanding the Behavior of Prometheus and Pandora
We revisit the dynamics of Prometheus and Pandora, two small moons flanking Saturn’s F ring. Departures of their orbits from freely precessing ellipses result from mutual interactions via their 121:118 mean motion resonance. Motions are chaotic because the resonance is split into four overlapping components. Orbital longitudes were observed to drift away from predictions based on Voyager epheme...
متن کاملGravitoelectrodynamics in Saturn’s F ring: encounters with Prometheus and Pandora
The dynamics of Saturn’s F ring have been a matter of curiosity ever since Voyagers 1 and 2 sent back pictures of the ring’s unusual features. Some of these images showed three distinct ringlets with the outer two displaying a kinked and braided appearance. Many models have been proposed to explain the braiding seen in these images; most of these invoke perturbations caused by the shepherding m...
متن کاملOrigin of Chaos in the Prometheus-Pandora System
We demonstrate that the chaotic orbits of Prometheus and Pandora are due to interactions associated with the 121:118 mean motion resonance. Differential precession splits this resonance into a quartet of components equally spaced in frequency. Libration widths of the individual components exceed the splitting resulting in resonance overlap which causes the chaos. A single degree of freedom mode...
