Abstract

Gilles de la Tourette Syndrome (GTS) is characterised by the presence of multiple motor and phonic tics with a fluctuating course of intensity, frequency and severity. Up to 90% of patients with GTS present with comorbid conditions, most commonly attention-deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), thus providing an excellent model for the exploration of shared aetiology across disorders. TS-EUROTRAIN (FP7-PEOPLE-2012-ITN, Grant Agr.No.316978) is a Marie Curie Initial Training Network (http://ts-eurotrain.eu) that aims to elucidate the complex aetiology of the onset and clinical course of GTS, investigate the neurobiological underpinnings of GTS and related disorders, translate research findings into clinical applications and establish a pan-European infrastructure for the study of GTS. This includes the challenges of (i) assembling a large genetic database for the evaluation of the genetic architecture with high statistical power; (ii) exploring the role of gene-environment interactions including the effects of epigenetic phenomena; (iii) employing endophenotype-based approaches to understand the shared aetiology between GTS, OCD and ADHD; (iv) establishing a developmental animal model for GTS; (v) gaining new insights into the neurobiological mechanisms of GTS via cross-sectional and longitudinal neuroimaging studies; and (vi) partaking in outreach activities including the dissemination of scientific knowledge about GTS to the public. Fifteen partners from academia and industry and twelve PhD candidates pursue the project. Our ultimate aims are to elucidate the complex aetiology and neurobiological underpinnings of GTS, translate research findings into clinical applications and establish Pan-European infrastructure for the study of GTS and associated disorders.

Abstract

Intellectual disability (ID) is characterized by an intelligence quotient of below 70 and impaired adaptive skills. Here, analyzing whole genome sequences from 31,463 Icelanders, Walters et al. identify variants in MAP1B associated with ID and extensive brain-wide white matter deficits.

Abstract

Plants have the ability to show responses against various environmental stresses. It is one of the necessities to understand stress response mechanisms to improve crops productivity and quality, under the stressed condition. The AP2/ERF transcription factors are one of the putative candidates that are involved in the regulation of biotic and abiotic stress. Most of the research has been conducted on functional analysis of AP2/ERF genes in many plants; however, a comprehensive review is required to show a broad picture of functionally characterized AP2/ERF in different plants. In this study, a comprehensive review is carried on genome-wide studies of AP2/ERF gene family and their evolutionary divergence in plant species including mustard (Arabidopsis, brassica), cereal (rice, wheat, maize, sorghum), and fiber (upland cotton and island cotton). Review exhibited that AP2/ERF superfamily is classified into four sub-families e.g. AP2, DREB, ERF, RAV and solicit, in which the ERF was the largest sub-family of AP2/ERF superfamily. Each subfamily was further divided into multiple groups and sub-groups. Furthermore, each plant species showed different number of paralogs showing correspondence to the plant genome size .e.g. higher genome possess higher gene copy number. The change in copy number may be due to either tandem gene duplication or whole genome duplication during evolutionary adaptation that developed special feature in plant species under environmental stresses. Moreover, current study also surveyed on the expression of AP/ERF genes with the conclusion that expression of AP2/ERF produced tolerance against biotic and abiotic stresses. However further studies are required to improve crops resistance by studying the same variables and gene families in different plants.

Abstract

Background: Tourette syndrome (TS) is a childhood-onset neurodevelopmental disorder of complex genetic architecture and is characterized by multiple motor tics and at least one vocal tic persisting for more than 1 year. Methods: We performed a genome-wide meta-analysis integrating a novel TS cohort with previously published data, resulting in a sample size of 6133 individuals with TS and 13,565 ancestry-matched control participants. Results: We identified a genome-wide significant locus on chromosome 5q15. Integration of expression quantitative trait locus, Hi-C (high-throughput chromosome conformation capture), and genome-wide association study data implicated the NR2F1 gene and associated long noncoding RNAs within the 5q15 locus. Heritability partitioning identified statistically significant enrichment in brain tissue histone marks, while polygenic risk scoring of brain volume data identified statistically significant associations with right and left thalamus volumes and right putamen volume. Conclusions: Our work presents novel insights into the neurobiology of TS, thereby opening up new directions for future studies.
