Personal genomics today: 23 and We Family Inheritance Recombination breakpoints Me vs. my brother My dad Mom’s dad Dad’s mom Human ancestry Disease risk Genomics: Regions mechanisms drugs Systems: genes combinations pathways
Understanding human variation and human disease Gene annotation Roles in gene/chromatin regulation (Coding, 5’/3’UTR, RNAs) Activator/repressor signatures Evolutionary signatures CATGACTG CATGCCTG Disease-associated Non-coding annotation Other evidence of function variant (SNP/CNV/…) Chromatin signatures Signatures of selection (sp/pop) • Challenge: from loci to mechanism, pathways, drug targets Goal: A systems-level understanding of genomes and gene regulation: • The regulators: Transcription factors, microRNAs, sequence specificities • The regions: enhancers, promoters, and their tissue-specificity The targets: TFs targets, regulators enhancers, enhancers genes • The grammars: Interplay of multiple TFs prediction of gene expression • The parts list = Building blocks of gene regulatory networks
Tools for interpreting the human genome • Evolutionary signatures Genome annotation – Distinct signatures for proteins, ncRNAs, miRNAs, motifs – Read-through, excess-constraint, networks,human selection • Chromatin signatures Dynamic regulatory regions – Define chromatin states from combinations of histone marks – Distinct classes of promoter/enhancer/transcribed/repressed • Activity signatures Link enhancer networks – Activity-based linking of regulators enhancers targets – Testing of 1000s of enhancer activator / repressor motifs • Personal genomics Interpret disease mechanism – Disease-associations: Mechanistic predictions for variants – Beyond top hits: 2000+ GWAS T1D-associated enhancers – Global methylation changes in Alzheimer’s: NRSF, ELK1, CTCF
