[Geuvadis_rna_analysis] analysis updates

by Tuuli Lappalainen

Hello, First a question: Who would like to present on Thursday's analysis group call? Next week we should discuss splicing QTLs (with results from Jean and myself), but this week's slot is free. Then a couple of analysis updates: - I've done some analysis on miRNA-mRNA interactions; namely on whether miRNA-cis-eQTLs show increased trans-signal to the targets of these miRNAs. The answer is maybe yes - the signal is small but significant. See http://sanabre.net/geuvadis/index.php/MiRNA-mRNA_interaction . - I've updated some normalizations of quantifications - I let some of you know about these already during the weekend, but for FYI for eneryone. Details in http://sanabre.net/geuvadis/index.php/Basic_methodology#Normalization_of_th… . These are quantifications done jointly on the 462 samples by PEER, and then transforming the residuals to standard normal (*norm* in the filename). There are files for miRNAs (full and seed-pooled), exons, splice junctions, introns, and transcripts in the directories below: /upload/geuvadis/wp4_rnaseq/main_project/analysis_data/mirna/quantification_tables /upload/geuvadis/wp4_rnaseq/main_project/analysis_data/quantification/exon/ /upload/geuvadis/wp4_rnaseq/main_project/analysis_data/quantification/splice_junction-intron /upload/geuvadis/wp4_rnaseq/main_project/analysis_data/quantification/splice_junction-intron /upload/geuvadis/wp4_rnaseq/main_project/analysis_data/quantification/transcript cheers, Tuuli -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch

[Geuvadis_rna_analysis] Wiki on some splicing features and sQTL

by Jean Monlong

Hi all, Just to let you know I put some results on the wiki about simple splicing features(http://sanabre.net/geuvadis/index.php/Qualitative_and_quantitative…, some alternative splicing comparison (http://sanabre.net/geuvadis/index.php/Alternative_splicing_analysis) and splicing QTL results (http://sanabre.net/geuvadis/index.php/Splicing_QTL_discovery_using_transcri…). Among the interesting results, again "cell division" popped up of the GO analysis when looking at genes with different splicing features and splicing QTL results look good with enrichment in exons, some good share across population and interesting GWAS hits nearby. I'll put the results file on the ftp tomorrow, I'll be happy to present/comment the analysis anytime(except next call because I'll be on the plane to Barcelona). Feedback/ideas are very welcome, Thanks, Jean

[Geuvadis_rna_analysis] main paper

by Tuuli Lappalainen

Hello, In order to keep things rolling for the main paper, I've put together a list of action items for all of us, as well as an early draft of supplemental figures and tables. The main figure draft has been updated a bit as well. There are plenty of placeholders for us to fill, and let's discuss these on the call tomorrow - these are definitely open for discussion. I'd also like to emphasize that now when we're finalizing the analysis and I'm trying my best to put it all together, we should have subgroup or one-on-one calls if you don't understand what I'm asking from you, or if it seems that I'm misunderstanding your analysis. best, Tuuli The action items are here (as well as in the attached document): Everyone - Text for the supplement: methods, results, and conclusions of your analysis. - Good-quality figures (see doc for details) - Deadline: October 20 Tuuli - finish splicing QTLs - plenty of downstream analysis of QTLs - rare variant mapping - Loss-of-function ASE NMD stats - ASAS / ASE sharing analysis - finish some QC analyses - ...a zillion other things Micha - Coordinate documentation of mRNA mapping and transcript quantification - Coordinate splicing paper - some plot(s) of splicing variation (coefficient of variation? Annotated/novel junctions vs population freq?) - Final figures: - gene discovery plot that works in smaller space - splice score distributions - allele frequency distributions for splicing score categories (DAF from annotations in vcf) Marc - miRNA-mRNA correlation analysis Jean - quantitative analysis of population differences (e.g. GBR-CEU looks visually the same as GBR-YRI, but is this really true numerically? Compare all population pairs) - prettier figures of transcript quantification stats - prettier figures of quantitative vs qualitative variation Mar & Pedro - Prepare a Venn-diagram of splice/expression differentiated genes and plot some examples Liliana - quantitative values of fusion events for QTL analysis - prettier frequency and distance plots Manny - Stop-gained NMD compensation - Splice effect modeling with Micha's scores - NMD prediction - Coordinate LoF paper Peter - coordinate QC paper Irina - results of repeat analysis - quantitative values for QTL analysis? Maarten - miRNA-mRNA correlation analysis Matthias - prettier plots that illustrate soft splicing variation: - phenomenon in general: the lineplot that shows the distances from the major spliceoform - population variation in an analogous way to Jean's analysis Daniela - results of n-TAR analysis - quantitative values of n-TARs for QTL analysis Thomas - results of RNA editing analysis - quantitative values of editing for QTL analysis Monkol & Daniel - annotation statistics (variants in each category) -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch

Note that we've extended the deadline to the 10th October 2012 Full survey link: https://qtrial.qualtrics.com/SE/?SID=SV_bHJDue550PwdFrv To describe the survey please use freely the following text: ------------------ THE GEUVADIS PROJECT - More information on our website: www.geuvadis.eu<file:///C:\Users\gbertier\Documents\GEUVADIS\Annual%20Meeting%202\www.geuvadis.eu> The latest high-throughput next-generation sequencing technologies allow investigators to sequence entire human genomes and transcriptomes at an affordable price and within a short time frame. An increasing number of research centers in Europe have access to these technologies, in-house or through regional, national and international infrastructures. Storing, disseminating and analysing the large amount of data produced generate major challenges. Tackling these challenges requires extensive exchange of data, information and knowledge between sequencing centers, bio-informatics networks, the medical research community and the industry at the European level. The GEUVADIS (Genetic EUropean VAriation in DISease) Consortium has four main aims: 1. Develop standards in quality control and assessment of sequence data 2. Develop models for sequencing data storage, access and exchange 3. Develop standards for the handling, analysis and interpretation of sequencing data from DNA (and RNA) 4. Develop guidelines on the handling of ethical, legal and social implications of phenotype prediction from sequence variation * PURPOSE OF SURVEY 1. Collect quantitative and qualitative information on the current status of DNA sequence production, storage, exchange and analysis in Europe. 2. Collect feedback from research/clinical centers on their main challenges and difficulties regarding the management of these large data-sets potentially containing important medical information 3. Collect information on local standardization efforts, and avoid duplication of efforts throughout Europe 4. Create a road-map/policy document outlining the necessary steps to take national standards to the European level * POTENTIAL PUBLICATION OF RESULTS 1. Results of this survey will be presented at an internal GEUVADIS workshop, on October 30-31st 2012. 2. We will disseminate the road-map to potential funders (private of public), including the European Commission and other possible national public funders. 3. We will submit an abstract to the Joint Conference of Human Genome Meeting 2013 and 21st International Congress of Genetics. * DEADLINE: 30.09.2012 --------------------- If you have any question or comment regarding the Annual Meeting, the workshop and/or the survey please don't hesitate to contact me.

[Geuvadis_rna_analysis] TC minutes

by Tuuli Lappalainen

Hello, Here are some badly belated minutes from last week's analysis group TC. The next call will be this Thursday, October 11 at 2pm CET. - There's a new conference call system of a shared screen and notes that we can use later if we want to - Maarten presented some early results from miRNA-mRNA correlations. The background null distribution looks good and unbiased, and hopefully refining the analysis a bit further will help us to get a significant signal out of this. - Micha presented a draft plot for the paper of how gene discoveries increase as a function of sequenced samples - After the main call we had a splicing subgroup call - different splicing measures and splice scores of variants seem to correlate nicely, there's plenty of data and analysis is going well, although there's plenty of things to do especially wrapping up the sQTLs. - The next call will have a splicing theme: Micha will present splice junction analyses, and if there's time Tuuli will present allele-specific alternative splicing. For those who are interested, I've already updated the wiki with ASAS methods analyses (http://sanabre.net/geuvadis/index.php/Allele_specific_alternative_splicing). best, Tuuli -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch
