Cognomics Summer School 2018

Brain Imaging Genetics: Genetics for Imagers

Nijmegen, Netherlands | 13-17 August 2018

The Dutch Cognomics Program is happy to announce the Cognomics summer school “Brain Imaging Genetics: Genetics for Imagers”! The 3-rd edition of the Cognomics summer school will be held in Nijmegen (the Netherlands) on 13-17 August 2018.

The course is directed at researchers with a neuroimaging background, who wish to develop their knowledge and skills on state‐of‐the‐art developments in the field of neuroimaging genetics. This intensive one-week course covers various aspects of genetics analyses of neuroimaging data. The course will start with basic information on the architecture of the human genome and the basis of heritability. We will then move on to the statistical analysis of single common genetic variant for the different imaging modalities (structural imaging based on (sub)cortical volumetry or diffusion tensor imaging and brain activity/functional connectivity based on (resting state) (MRI). This will be followed by analyses of whole gene and genome‐wide association studies and the meta analysis of such data, including high-dimensional whole genome association studies. Other important topics include the integration across levels of investigation and linking genetics to behaviour via the brain – the essence of Cognomics research.

The lecture programme will be supplemented with hands‐on computer exercises and demonstrations. You will also learn how to genotype single nucleotide polymorphisms and score the genotypes in the wetlab.

The faculty includes researchers involved in the largest imaging genetics consortium world‐wide – the ENIGMA Consortium – and the Dutch Cognomics Program.

The evenings will be reserved for social activities. The course will be ended with a closing ceremony, where a Radboud summer school certificate will be handing out to each participant.

Early bird deadline: 1 April 2018 (10% discount), application deadline: 1 June 2018.

Hong Kong, Atlanta events showcase ENIGMA’s worldwide brain initiatives

In a single week, ENIGMA researchers gathered in both Atlanta and Hong Kong to present the world’s largest brain imaging studies of major depression, obsessive compulsive disorder, and schizophrenia - and landmark findings from over 18 diseases that ENIGMA now studies. In Atlanta, Dr. Lianne Schmaal, who co-leads ENIGMA’s Major Depression initiative, presented data from over 10,000 individuals, detecting consistent patterns of brain abnormalities in people who are depressed worldwide. The landmark study, published in this month’s issue of Molecular Psychiatry freely available here,brought together experts from 57 institutions - from Australia, North America, Western Europe and Russia. The researchers combed through brain scans, detecting consistent patterns of abnormalities in the frontal and limbic brain regions. These brain regions have long been implicated in depressive symptoms and are the target of several antidepressant treatments. Dr. Odile van den Heuvel, a psychiatrist from the Netherlands who co-leads ENIGMA’s initiatives on obsessive compulsive disorder, also presented data from 26 OCD sites worldwide (including 1830 OCD patients and 1759 controls), revealing distinct patterns of brain abnormalities in children and adults with OCD. ABSTRACT HERE . ENIGMA researchers led a series of 4 symposia, at the Society for Biological Psychiatry in Atlanta, highlighting their large-scale brain studies. Many of them - such as ENIGMA’s Lifespan project presented by Dr. Sophia Frangou ABSTRACT HERE -are the largest brain studies ever performed - in terms of the numbers of scans, and the diversity of participation by scientists worldwide. In Hong Kong, ENIGMA PI Paul Thompson highlighted ENIGMA’s close partnerships with international networks such as AUSSIE, led by neurologist Dr. Jeff Looi, which brings together experts worldwide to study neurodegenerative diseases. At this event, at the Royal Australian and New Zealand Congress on Psychiatry, Dr. Looi noted the unprecedented power of global consortia to detect how treatments resist brain decline or symptoms of brain disease.

ENIGMA in Prague

ENIGMA scientists showcased their work in 8 technical papers at this month's ISBI 2016 conference, collated here:  http://bit.ly/1qVBtxz

One paper earned the prestigious ISBI 2016 Best Student Paper Award for first author, Qi Wang: the authors showed how to merge information from numerous sources on brain connectivity to better detect disease, applying novel concepts such as L1 fusion to brain networks and connectivity maps.

Other papers boosted the power to detect brain disease by using new metrics from diffusion tensor images (Nir et al., see booklet), and tensor based morphometry; ENIGMA's sparse learning algorithms were also showcased for encoding and decoding patterns in large databases of brain images, genomes, and clinical data (Zhu et al., and Lorenzi et al.).

ENIGMA is now performing a very large scale worldwide analysis of factors that affect the cortical patterns of the human brain (see Pizzagalli et al., in the booklet).

Dana Foundation highlights ENIGMA's Global Psychiatry Initiatives 

A news article from the Dana Foundation (http://www.dana.org/News/Team_Science/) 

highlights' ENIGMA's growing role in bringing together the scientific community to discover information in data, at a scale beyond the ability of any single lab to gather and analyze. Award-winning science journalist, Carl Sherman, highlights ENIGMA's initiatives - including a recent partnership with the Psychiatric Genomics Consortium, analyzing brain imaging and genetic data on more than 50,000 people, enlisting more than 500 investigators world-wide to seek connections between mental illness and brain morphology and function. In the latest paper, in Nature Neuroscience, researchers matched genes associated with schizophrenia risk from GWAS of more than 76,000 patients and controls in the PGC dataset against genes associated with brain volume in 11,840 subjects gathered by ENIGMA. the work was a successful proof-of-concept study, says Thompson, “a roadmap of partnership between PGC and ENIGMA. It showed that you can pool genomic and imaging data in a way to test whether psychiatric risk genes alter brain structure or function.” Such a partnership represents “a two-way conversation, between gene-hunters in imaging and in psychiatry, comparing their hands of cards.” - See more at: http://www.dana.org/News/Team_Science/

ENIGMA and PGC Publish a Joint Roadmap for Future Collaborations

ENIGMA has partnered with the Psychiatric Genomics Consortium (PGC; http://pgc.unc.edu/) to investigate possible genetic ‘overlap’ between brain measures (e.g. subcortical volume, white matter microstructure) and risk for psychiatric disorders (e.g. schizophrenia, bipolar disorder). The first major collaboration between the consortia, published in this month’s Nature Neuroscience, provides a comprehensive roadmap for future studies of genetic covariance, applying a series of novel techniques (including Rank Rank Hypergeometric Overlap (RRHO), genetic predisposition scoring, conjunction analysis and linkage disequilibrium score regression (LDSR)) to test for possible statistical overlap between a large-scale genome-wide association (GWA) meta-analysis of schizophrenia (PGC, Nature, 2014) and seven independent GWA meta-analyses of subcortical brain volumes, including the nucleus accumbens, amygdala, caudate nucleus, hippocampus, pallidum, putamen and thalamus, in addition to an eighth independent GWA meta-analysis of intracranial volume (ICV; Hibar et al., Nature, 2015). The study did not reveal any significant genetic correlations between subcortical/intracranial volume measures and risk for schizophrenia. However, as the ENIGMA consortium expands its genome-wide association studies of novel brain phenotypes (including cortical thickness/surface area and white matter microstructure) and the PGC explores a broad body of psychiatric illnesses with ever-increasing sample sizes, this inaugural study should serve as an important proof-of-concept for future collaborations between the two.

MOSCOW, 12/11/15 In a series of interviews on Russian national television, Dr. Vladimir Zelman, ENIGMA Coordinator in Russia, noted the vibrant partnerships in ENIGMA across Russia that are now producing groundbreaking discoveries about the human brain. The Russian Deputy Minister for Science and Education, Dr. Lyudmila Ogorodova, attended ENIGMA’s meetings and noted her strong support for ENIGMA and its established and extensive partnerships with other Russian science initiatives, such as Co-Brain, and NeuroNEXT. ENIGMA’s 500 scientists now study 12 brain diseases in over from 35 countries, and have published the largest-ever genomic analyses of the brain. As part of a week of ENIGMA-related events in Russia, Dr. Zelman, and ENIGMA director Paul Thompson, noted the remarkable breadth of participation in ENIGMA by mathematicians, geneticists, and clinical neuroscientists across Russia. “We see a great surge of interest in ENIGMA, which is widely known across Russia”, Zelman told Rossiya 24, a national news channel of the Russian Federation. Zelman is a Russian-born scientist, trained at the Meshalkin Institute in Novosibirsk. A member of the Russian National Academy of Sciences, Zelman has helped to build up a network of scientists contributing to ENIGMA across Russia. Russian scientists are now deeply involved in ENIGMA’s projects on Parkinson’s disease, major depression, post traumatic stress, and developmental disorders in children, including ADHD. ENIGMA co-founder, Paul Thompson, co-hosted a planning meeting for Russian ENIGMA members chaired by developmental neuroscientist Dr. Leyla Namazova, at the Child Health Institute in Moscow, on December 8th. The meeting, attended by ENIGMA laboratory directors from across Russia, Siberia, and Ukraine, gave all scientists a forum to update each other on their scientific work as part of ENIGMA. Interviewed by Scientific American’s Russian magazine, Thompson pointed to developments being accelerated by ENIGMA’s Russian scientists in the fields of genomics, machine learning, and analysis of brain connectivity, such as finding patterns in medical data to detect and classify autism spectrum disorder and Alzheimer’s disease. Dr. Namazova, who co-directs Moscow’s largest children’s hospital, chaired an evening session about ENIGMA with institute directors, radiologists and computer scientists from the Moscow Institute of Neurology, Siberian National Academy of Sciences, and Skoltech University (see photo). Paul Thompson supported the Moscow Child Health Center’s plans to host a training workshop for ENIGMA next December in Moscow – training young scientists is a key mission of ENIGMA, which now supports a productive international exchange program. Zelman hosted an awards ceremony for young scientists at Skoltech – Moscow’s $100M technical university focusing on engineering and business start-ups in informatics – after Thompson’s keynote talk highlighting ENIGMA’s work in Russia. Sergey Illarioshkin, MD, a leader in the genetics of Parkinson’s disease, presented his team’s work at the Moscow Institute of Neurology, mapping brain abnormalities as part of ENIGMA’s Parkinson’s disease working group. This group now analyzes brain MRI scans of Parkinson’s disease patients from Russia, Italy, and The Netherlands, to identify preventable risk factors for the disease. Lyubomir Aftanas MD PhD, a psychiatrist who runs a brain mapping center in Novosibirsk, presented a his work on ENIGMA-Depression, which compares Siberian datasets to others worldwide, in what is now the largest brain imaging study of depression ever conducted (see photo). “ENIGMA gives us a power we have not had”, said Aftanas. “We contribute data and expertise to ENIGMA’s efforts in neurology and psychiatry; after brainstorming in Moscow this week, we are keen to join ENIGMA’s epigenetics and lifespan projects, among others, to study modifications of the genome throughout life and how they impact the brain. In Siberia, we are collecting unique data to help answer these questions”. At the meeting, neurosurgical delegates from Ukraine outlined their plans to participate in ENIGMA next year, offering to contribute genetic and brain scan data from patients with a range of brain disorders. In two days of highly animated sessions of the Russian National Academy of Sciences, a series of workshops and symposia hailed ENIGMA’s work bringing scientists together, as part of “Moscow Science Week”. ENIGMA director Paul Thompson thanked senior members of the Russian Academy, including its President, noted physicist Vladimir Fortov, for supporting ENIGMA and promoting its ongoing projects to their colleagues; Karkhevich Institute director, Dr. Alexander Kuleshov, noted that he is sending 3 mathematicians to the ENIGMA Center in Los Angeles to boost the ongoing machine learning efforts to discover genomic markers of brain disease. Kuleshov leads “big data” analysis efforts with Airbus and aerospace industry partners. He pointed to the power of worldwide collaboration in informatics in solving pressing problems in science. Using large-scale analyses, ENIGMA has been publishing “big data” papers with hundreds of scientists in high-impact journals such as Nature and Nature Genetics. Russian scientists have long been a key source of expertise for ENIGMA, since noted Moscow geneticist Kazima Bulayeva published a series of reports in 2012 from her cohorts in the highlands of Dagestan. Her work reveals how genes implicated by ENIGMA affect brain structure and people’s risk for mental retardation and psychosis. Understanding the transmission of these genetic sources of risk underlies partnerships between her team’s work in populaton genetics and ENIGMA’s work on the genetics of the human brain. Interviewed by Russia’s Scientific American, Paul Thompson was asked if ENIGMA’s mathematicians had found what the Russian poet Pushkin described as “harmony in the brain”, pointing to ENIGMA’s findings mapping the brain’s interacting circuits and systems. Vladimir Zelman pointed to both successes and challenges leading ENIGMA’s efforts in Russia, and how Russian politicians and institute directors across Moscow and Siberia have helped to overcome them. The full interview will be published in Russia’s Scientific American, next month.

ENIGMA and the Individual - An Up-to-Date Review of ENIGMA

12/09/2015 ENIGMA has published a broad overview of its activities in the December 2015 issue of the journal, NeuroImage. In the review, available here, we discuss recent work by the ENIGMA Consortium (https://enigma.ini.usc.edu) - a global alliance of over 500 scientists spread across 200 institutions in 35 countries collectively analyzing brain imaging, clinical, and genetic data. Initially formed to detect genetic influences on brain measures, ENIGMA has grown to over 30 working groups studying 12 major brain diseases by pooling and comparing brain data. In some of the largest neuroimaging studies to date – of schizophrenia and major depression – ENIGMA has found replicable disease effects on the brain that are consistent worldwide, as well as factors that modulate disease effects. In partnership with other consortia including ADNI, CHARGE, IMAGEN and others, ENIGMA’s genomic screens – now numbering over 30,000 MRI scans – have revealed at least 8 genetic loci that affect brain volumes. Downstream of gene findings, ENIGMA has revealed how these individual variants – and genetic variants in general – may affect both the brain and risk for a range of diseases. The ENIGMA consortium is discovering factors that consistently affect brain structure and function that will serve as future predictors linking individual brain scans and genomic data. It is generating vast pools of normative data on brain measures – from tens of thousands of people – that may help detect deviations from normal development or aging in specific groups of subjects. We discuss challenges and opportunities in applying these predictors to individual subjects and new cohorts, as well as lessons we have learned in ENIGMA’s efforts so far.

ENIGMA Partners to merge techniques from Big Data powerhouses 

07/22/2015

The ENIGMA Center of Excellence, based at the University of Southern California, will work with the KnowEnG (Knowledge Engine for Genomics) Center, based at the University of Illinois, as part of an ambitious new collaboration funded by the Big Data to Knowledge (BD2K) initiative.

Drawing upon recent advances in genome sequencing, genome-wide association studies (GWAS) have  have led to a wealth of discoveries by mining the human genome for common variants in our genetic sequence that relate to our risk for a range of diseases. A major challenge for GWAS, however, is that the number of SNPs - locations in DNA where people differ in their genetic make-up - is much larger than the number of subjects who can be assessed in a study.

As part of this collaboration, the ENIGMA and KnowEnG centers will mine existing databases of biological pathways and genetic perturbation screening datasets to discover important new genetic interactions and construct networks of gene interactions, called "epistasis networks". These novel epistasis networks will provide prior information needed to expand sparse learning models and enhance the power of future genome-wide genetic analyses.

This collaborative project will leverage the strengths of the KnowEng center (knowledge of gene-gene interactions) with those of the ENIGMA Center (ongoing development of sparse learning models) to improve our ability to identify causal single nucleotide polymorphisms (SNPs). The project will be coordinated by Jieping Ye and Paul Thompson (ENIGMA) and David Zhao, Jiawei Han & Jun S. Song (KnowEnG).

ENIGMA in Molecular Psychiatry

Work from the ENIGMA-Major Depressive Disorder and ENIGMA-Schizophrenia working groups has been published in Molecular Psychiatry. The first study, 'Subcortical brain volume abnormalities in 2028 individuals with schizophrenia and 2540 healthy controls via the ENIGMA consortium', identified (i) significant volume reductions in the hippocampus, amygdala, thalamus, accumbens and intracranial area and (ii) significant volume augmentations in the pallidum and lateral ventricles. The latter volume augmentations were positively associated with duration of illness. The second study, 'Subcortical brain alterations in major depressive disorder: findings from the Disorder working group' , found consistent patterns of hippocampal volume reduction in depressed patients compared to healthy controls. This study, the largest of its kind in MDD, has received press coverage from The Guardian, The Conversation and many other media outlets.
