Two approaches to integrating phenotype and clinical information.

ABSTRACT: Linkages between animal models of diseases and human data enable the development of translational research hypotheses. The objective of this study is to investigate two approaches to integrating phenotype and clinical information. On the one hand, we develop a terminology mapping between phenotypes from the Mammalian Phenotype Ontology (MPO) and Online Mendelian Inheritance in Man (OMIM) through the Unified Medical Language System (UMLS). On the other, we associate MPO phenotypes with OMIM manifestations through annotations made to orthologous genes. 1,469 MPO concepts (22%) were mapped successfully to some disease concept in the UMLS, of which 869 were present in OMIM. Among the 16,764 distinct MGI genes associated with human orthologs, 1,968 distinct genes were associated with both MPO and OMIM annotations. The UMLS is a valuable resource for linking phenotype terms to clinical terminologies, and these mappings between terminologies can help enrich gene annotation databases and unify phenotype representation.

Project description:Social information use is widespread in the animal kingdom, helping individuals rapidly acquire useful knowledge and adjust to novel circumstances. In humans, the highly interconnected world provides ample opportunities to benefit from social information but also requires navigating complex social environments with people holding disparate or conflicting views. It is, however, still largely unclear how people integrate information from multiple social sources that (dis)agree with them, and among each other. We address this issue in three steps. First, we present a judgement task in which participants could adjust their judgements after observing the judgements of three peers. We experimentally varied the distribution of this social information, systematically manipulating its variance (extent of agreement among peers) and its skewness (peer judgements clustering either near or far from the participant's judgement). As expected, higher variance among peers reduced their impact on behaviour. Importantly, observing a single peer confirming a participant's own judgement markedly decreased the influence of other-more distant-peers. Second, we develop a framework for modelling the cognitive processes underlying the integration of disparate social information, combining Bayesian updating with simple heuristics. Our model accurately accounts for observed adjustment strategies and reveals that people particularly heed social information that confirms personal judgements. Moreover, the model exposes strong inter-individual differences in strategy use. Third, using simulations, we explore the possible implications of the observed strategies for belief updating. These simulations show how confirmation-based weighting can hamper the influence of disparate social information, exacerbate filter bubble effects and deepen group polarization. Overall, our results clarify what aspects of the social environment are, and are not, conducive to changing people's minds.
