The algorithm’s name, Phrank — a mashup of “phenotype” and “rank” — hints at how it works: Phrank compares a patient’s symptoms and gene data to a knowledge base of medical literature, generating a ranked list of which rare genetic diseases are most likely to be responsible for the symptoms.

Outside of the lab, he enjoys designing holiday cards, t-shirts, and music videos, and is a scientific illustrator. “You might get the result that mouse experiments cause phenotypes similar to your patient, that you may have found the first human patient that suffers from this disease,” Bejerano said. We aimed to automatically construct a freely accessible database of pathogenic variants directly from full-text articles about genetic disease. Mentor: Gill Bejerano, Developmental Biology, Computer Science, and Pediatrics. Stanford’s departments of Developmental Biology, of Computer Science and of Pediatrics also supported the work. Stanford Medicine Scope - July 17th, 2018 - by Erin Digitale Today, diagnosing rare genetic diseases requires a slow process of educated guesswork. Stanford University; Cole Deisseroth. The most time-consuming part of genome based diagnosis is the manual step of matching the potentially long list of patient candidate genes to patient phenotypes to identify the causative disease. ClinPhen extracts and prioritizes patient phenotypes directly from medical records to expedite genetic disease diagnosis. “If I’m a busy clinician, before I even open a patient’s case, the computer needs to have done all it can to make my life easier.”.

Poster presented at the Stanford Bio-X Interdisciplinary Initiatives Symposium on August 24, 2017: … Karthik A. Jagadeesh*, Johannes Birgmeier*, Harendra Guturu, Without computer help, this match-up process takes 20-40 hours per patient: The expert looks at a list of around 100 of the patient’s suspicious-looking mutations, makes an educated guess about which one might cause disease, checks the scientific literature, then moves on to the next one. Researchers have found that analyzing mutations in regions of the genome that control genes can predict medical conditions such as hypertension, narcolepsy and heart problems.

Baylor College of Medicine; Maximilian Haeussler. To speed this process, Birgmeier et al . The mathematical workings of Phrank aren’t tied to a specific database, a first for this type of algorithm. This makes it much more flexible to use. See who else is on board LoFi MedFi. Phrank also dramatically outperforms earlier algorithms that have tried to do the same thing, according to the paper. Stanford University ... Cole Deisseroth [...] Gill Bejerano. But new technology could help experts use their time more efficiently, helping many more patients get diagnosed, he said. In a continued effort to speed up the diagnostic process of severe genetic diseases, Stanford's Gill Bejerano, PhD, and his colleagues have developed a new algorithm that can quickly locate important disease-related information within a patient's medical record.. The Deisseroth Lab is part of the Bioengineering Department at Stanford University. Mail Code: 4245. email@example.com. In a paper published July 12 in Genetics in Medicine, Bejerano and his colleagues describe an algorithm they’ve developed that automates the most labor-intensive part of genetic diagnosis: that of matching a patient’s genetic sequence and symptoms to a disease described in the scientific literature. Purpose Exome sequencing and diagnosis is beginning to spread across the medical establishment. A Stanford method for comparing patients’ symptoms and gene data to the medical literature could greatly speed the diagnosis of rare genetic diseases. Genetic disease diagnosis can be time-consuming because of the extensive literature searching required. The work was funded by Stanford graduate fellowships, Stanford Bio-X, DARPA, the David and Lucile Packard Foundation and Microsoft. An analysis web portal with our most recent update, programmatic interface and code will be available at [AMELIE.stanford.edu]. Gill Bejerano, PhD, associate professor of developmental biology and of computer science at Stanford, is working to speed it up. Peter D Stenson. They refined their technique, which is now widely used in labs all over the world, to enable them to deliver light directly to the brains of mice via a fiber-optic cable. A major contributor to the scientific reproducibility crisis has been that the results from homogeneous, single-center studies do not generalize to heterogeneous, real world populations.

Email her at, Stanford Health Care (formerly Stanford Hospital & Clinics), Lucile Packard Children's Hospital Stanford, Individuals' medical histories predicted by their noncoding genomes. Prior studies had tested algorithms on made-up patients instead because real-patient data for this research is hard to come by.
