PsychENCODE Brain Expression Models

2020-07-19 Sabrina Mi
𝔾andal et al analyzed autism spectrum disorder, schizophrenia, and bipolar disorder across multiple levels of transcriptomic organization—gene expression, local splicing, transcript isoform expression, and coexpression networks for both protein-coding and noncoding genes to produce a quantitative, … Read more →

GTEx V8 Model Release

2019-12-11 PredictDB Team
𝕎e have recently published a new set of prediction models trained on GTEx v8 data (as part of efforts detailed in this preprint. We have overhauled the model construction, incorporating posterior inclusion probabilities and global patterns of tissue sharing, while also benefiting from larger sample … Read more →

EpiXcan Models - Integrated Epigenetics

2019-08-23 PredictDB Team

Database update: prediction models using 1KG SNP set

2016-11-16 PredictDB Team
𝕋oday we are updating the tissue-wide prediction models trained from GTEx data which use 1000 Genomes SNPs. There are two main differences: […] The snp covariance files we had provided previously were built using a reference dataset with 1000 genomes data. Now the covariance data is based off … Read more →
