Correlates of Cognitive Phenotype Severity in Autism Spectrum Disorders

Abstract: An important goal of genetic research is to understand the phenotypic consequences of diverse genetic mutations. However, progress towards this goal is difficult for common disorders with complex phenotypes, such as cognitive phenotypes in autism spectrum disorders (ASDs).

We analyzed de novo likely gene-disrupting (LGD) mutations identified in ASD probands from the Simons Simplex Collection. Specifically, we explored correlations between molecular and genetic properties of these mutations and cognitive phenotypes in affected probands, measured by intellectual quotients (IQ).

To explore the generality of our findings, we analyzed genomic and transcriptomic data across multiple human tissues, obtained from the GTEx consortium, and asked whether relationships could be found between properties of LGD variants and their effects on gene expression.

Surprisingly, we found that LGD mutations in the same gene often resulted in different phenotypes. However, we also identified properties of mutations that appear to correlate with phenotypic severity. Furthermore, these patterns were reproducible in gene expression studies across multiple human tissues, suggesting that the findings may be general.

Our results suggest that large cohort sequencing could achieve clinically useful predictions of cognitive phenotypes in ASDs. Also, similar patterns may be observed in other diseases with substantial contributions from de novo mutations.

MetaSRA: Normalized Sample-Specific Metadata for the Sequence Read Archive

Abstract: Motivation: The NCBI's Sequence Read Archive (SRA) promises great biological insight if one could analyze the data in the aggregate; however, the data remain largely underutilized, in part, due to the poor structure of the metadata associated with each sample. The rules governing submissions to the SRA do not dictate a standardized set of terms that should be used to describe the biological samples from which the sequencing data are derived. As a result, the metadata include many synonyms, spelling variants, and references to outside sources of information. Furthermore, manual annotation of the data remains intractable due to the large number of samples in the archive. For these reasons, it has been difficult to perform large-scale analyses that study the relationships between biomolecular processes and phenotype across diverse diseases, tissues, and cell types present in the SRA.

MeTeOR: Literature-Based Hypotheses Generation and Precision Medicine

Abstract: With over twenty-four million articles and an exponential growth rate, it has become difficult to stay abreast of the PubMed literature. To address this problem, we have created a novel biological network that aggregates data from millions of PubMed articles. This network, called MeTeOR (MeSH Term Objective Reasoning network), converts manually curated MeSH terms that tag PubMed articles into a global, structured summary of biological information for data-driven discovery. When compared to the current knowledge representations in many standard curated databases regarding associations among genes, drugs, and diseases, MeTeOR contains both confirmatory as well as novel information. Furthermore, when a hypotheses-generating algorithm is applied to the MeTeOR network, it suggests new potential disease or drug associations for most genes. In the most realistic test of performance—a time-stamped analysis, hypotheses generated from a MeTeOR network based on the literature prior to 2014, were shown to have significant predictive power for discoveries that were published after 2014. These data support MeTeOR as a promising representation of the biomedical literature, that may provide ready access to high-quality information about the relationships linking genes, drugs, and diseases, and also that support novel hypotheses towards systems analysis and precision medicine.
