Phenotype risk scores identify patients with unrecognized Mendelian disease patternsGenetic association studies often examine features independently, potentially missing subpopulations with multiple phenotypes that share a single cause. We describe an approach that aggregates phenotypes on the basis of patterns described by Mendelian diseases. We mapped the clinical features of 1204 Mendelian diseases into phenotypes captured from the electronic health record (EHR) and summarize

Random heteropolymers preserve protein function in foreign environmentsThe successful incorporation of active proteins into synthetic polymers could lead to a new class of materials with functions found only in living systems. However, proteins rarely function under the conditions suitable for polymer processing.

Organometallic and radical intermediates reveal mechanism of diphthamide biosynthesisDiphthamide biosynthesis involves a carbon-carbon bond-forming reaction catalyzed by a radical S-adenosylmethionine (SAM) enzyme that cleaves a carbon-sulfur (C–S) bond in SAM to generate a 3-amino-3-carboxypropyl (ACP) radical. Using rapid freezing, we have captured an organometallic intermediate with an iron-carbon (Fe–C) bond between ACP and the enzyme’s [4Fe-4S] cluster. In the presence of th

GDV1 induces sexual commitment of malaria parasites by antagonizing HP1-dependent gene silencingMalaria is caused by Plasmodium parasites that proliferate in the bloodstream. During each replication cycle, some parasites differentiate into gametocytes, the only forms able to infect the mosquito vector and transmit malaria.

CRISPR genetic editing takes another big step forward, targeting RNAMost people have heard of the CRISPR/Cas9 gene-editing technology, which acts as targeted molecular scissors to cut and replace disease-causing genes with healthy ones. But DNA is only part of the story; many genetic diseases are caused by problems with RNA, a working copy of DNA that is translated into proteins.
