BackgroundCohen Syndrome (COH1) is a rare autosomal recessive disorder, principally identified by ocular, neural and muscular deficits. We identified three large consanguineous Pakistani families with intellectual disability and in some cases with autistic traits.MethodsClinical assessments were performed in order to allow comparison of clinical features with other VPS13B mutations. Homozygosity mapping followed by whole exome sequencing and Sanger sequencing strategies were used to identify disease-related mutations.ResultsWe identified two novel homozygous deletion mutations in VPS13B, firstly a 1 bp deletion, NM_017890.4:c.6879delT; p.Phe2293Leufs*24, and secondly a deletion of exons 37-40, which co-segregate with affected status. In addition to COH1-related traits, autistic features were reported in a number of family members, contrasting with the "friendly" demeanour often associated with COH1. The c.6879delT mutation is present in two families from different regions of the country, but both from the Baloch sub-ethnic group, and with a shared haplotype, indicating a founder effect among the Baloch population.ConclusionWe suspect that the c.6879delT mutation may be a common cause of COH1 and similar phenotypes among the Baloch population. Additionally, most of the individuals with the c.6879delT mutation in these two families also present with autistic like traits, and suggests that this variant may lead to a distinct autistic-like COH1 subgroup.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by the selective death of motor neurons. Causative mutations in the global RNA-processing proteins TDP-43 and FUS among others, as well as their aggregation in ALS patients, have identified defects in RNA metabolism as an important feature in this disease. Lethal congenital contracture syndrome 1 and lethal arthrogryposis with anterior horn cell disease are autosomal recessive fetal motor neuron diseases that are caused by mutations in another global RNA-processing protein, hGle1. In this study, we carried out the first screening of GLE1 in ALS patients (173 familial and 760 sporadic) and identified 2 deleterious mutations (1 splice site and 1 nonsense mutation) and 1 missense mutation. Functional analysis of the deleterious mutants revealed them to be unable to rescue motor neuron pathology in zebrafish morphants lacking Gle1. Furthermore, in HeLa cells, both mutations caused a depletion of hGle1 at the nuclear pore where it carries out an essential role in nuclear export of mRNA. These results suggest a haploinsufficiency mechanism and point to a causative role for GLE1 mutations in ALS patients. This further supports the involvement of global defects in RNA metabolism in ALS.

Objective:Autism spectrum disorder (ASD) is a lifelong neurodevelopmental condition that is associated with significant difficulties in adaptive behavior and variation in clinical outcomes across the life span. Some individuals with ASD improve, whereas others may not change significantly, or regress. Hence, the development of “personalized medicine” approaches is essential. However, this requires an understanding of the biological processes underpinning differences in clinical outcome, at both the individual and subgroup levels, across the lifespan.Methods:The authors conducted a longitudinal follow-up study of 483 individuals (204 with ASD and 279 neurotypical individuals, ages 6–30 years), with assessment time points separated by ∼12–24 months. Data collected included behavioral data (Vineland Adaptive Behavior Scale–II), neuroanatomical data (structural MRI), and genetic data (DNA). Individuals with ASD were grouped into clinically meaningful “increasers,” “no-changers,” and “decreasers” in adaptive behavior. First, the authors compared neuroanatomy between outcome groups. Next, they examined whether deviations from the neurotypical neuroanatomical profile were associated with outcome at the individual level. Finally, they explored the observed neuroanatomical differences’ potential genetic underpinnings.Results:Outcome groups differed in neuroanatomical features (cortical volume and thickness, surface area), including in “social brain” regions previously implicated in ASD. Also, deviations of neuroanatomical features from the neurotypical profile predicted outcome at the individual level. Moreover, neuroanatomical differences were associated with genetic processes relevant to neuroanatomical phenotypes (e.g., synaptic development).Conclusions:This study demonstrates, for the first time, that variation in clinical (adaptive) outcome is associated with both group- and individual-level variation in anatomy of brain regions enriched for genes relevant to ASD. This may facilitate the move toward better targeted/precision medicine approaches.

International audience; As an integral part of autism spectrum symptoms, sensory processing issues including both hypo and hyper sensory sensitivities. These sensory specificities may result from an excitation/inhibition imbalance with a poorly understood of their level of convergence with genetic alterations in GABA-ergic and glutamatergic pathways. In our study, we aimed to characterize the hypo/hyper-sensory profile among autistic individuals. We then explored its link with the burden of deleterious mutations in a subset of individuals with available whole-genome sequencing data. To characterize the hypo/hyper-sensory profile, the differential Short Sensory Profile (dSSP) was defined as a normalized and centralized hypo/hypersensitivity ratio from the Short Sensory Profile (SSP). Including 1136 participants (533 autistic individuals, 210 first-degree relatives, and 267 controls) from two independent study samples (PARIS and LEAP), we observed a statistically significant dSSP mean difference between autistic individuals and controls, driven mostly by a high dSSP variability, with an intermediated profile represented by relatives. Our genetic analysis tended to associate the dSSP and the hyposensitivity with mutations of the GABAergic pathway. The major limitation was the dSSP difficulty to discriminate subjects with a similar quantum of hypo- and hyper-sensory symptoms to those with no such symptoms, resulting both in a similar ratio score of 0. However, the dSSP could be a relevant clinical score, and combined with additional sensory descriptions, genetics and endophenotypic substrates, will improve the exploration of the underlying neurobiological mechanisms of sensory processing differences in autism spectrum.

Posté sur medRxiv le 24 juillet 2020.; ImportanceSchizophrenia, educational attainment, and intelligence are all genetically correlated with autism. However, autism is a complex condition, with several different core (such as social communication difficulties and repetitive and restricted behaviour) and associated features (such as IQ and adaptive behaviour) contributing to the underlying heterogeneity. It is unknown to what extent polygenic scores (PGS) for these three phenotypes are associated with the core and associated autism features.ObjectiveTo investigate the association of PGS for intelligence, educational attainment and schizophrenia on core autism features, IQ and adaptive behaviour in autistic individuals. To further investigate the effects of stratifying by sex and IQ on these associations.DesignPGS association for the three phenotypes with 12 different autism core and associated features in three cohorts followed by meta-analysis. We additionally conducted sensitivity analyses by stratifying for sex and IQ.Settings :Three cross-sectional, multi-centre cohorts comprising autistic with genotype data, and phenotypic information.ParticipantsAutistic individuals (total N: 2,512 – 3,681) from three different cohorts: Simons Simplex Collection (Nmax = 2,233), Autism Genetic Research Exchange (Nmax = 1,200), and AIMS-2- TRIALS LEAP (Nmax = 262)Main outcome measuresAssociation of PGS for intelligence, educational attainment, and schizophrenia with core autism features, measures of intelligence, and adaptive behaviour in autistic individualsResultsWe identified a similar pattern of correlation among core and associated autism features across all three cohorts. Cluster analyses of these features identified two broad clusters – one consisting of the core features, and another consisting of IQ and adaptive behaviour. PGS for intelligence were only associated with measures of intelligence and adaptive behaviour (e.g. for full-scale IQ, Beta = 0.08, 95%CI = 0.11 – 0.04) for PGS for educational attainment were associated for measures of intelligence, adaptive behaviour, and additionally, non-verbal communication as measured by ADI – a core-autism feature (e.g. for full-scale IQ, Beta = 0.05, 95%CI = 0.08 – 0.02; for ADI non-verbal communication, Beta = 0.05, 95%CI = 0.09 – 0.01). Finally, PGS for schizophrenia were associated with two core autism features: restricted and repetitive behaviour and verbal communication difficulties as measured by the ADI-R (e.g. for ADI restricted and repetitive behaviour: Beta = 0.06, 95%CI = 0.09 – 0.02). Most of these associations were also significant when restricting it to males only or to individuals with IQ > 70. We find limited evidence for heterogeneity between cohorts.Conclusion and relevanceWe identify specific and different patterns of association between PGS for the three phenotypes and core and associated autism features. This provides greater resolution into the shared genetics between autism and the three phenotypes, and suggests one method to investigate heterogeneity in autism and co-occurring conditions.

Posté sur medRxiv le 6 mars 2021.; While over 100 genes are now significantly associated with autism spectrum disorders (ASD), the penetrance of the variants affecting these genes remains poorly understood. Here, we quantified the prevalence of rare loss-of-function (LoF) mutations affecting 156 genes robustly associated with ASD (SPARK genes) using genetic data from more than 10,000 individuals with ASD and 100,000 undiagnosed individuals. We then investigated the clinical, brain imaging and genetic profiles of individuals heterozygous for these rare deleterious variants who were not diagnosed with ASD. These “resilient” individuals, observed in less than 1% of the general population, were equally distributed among males and females, but displayed low polygenic scores for ASD compared to LoF heterozygotes diagnosed with ASD. The interplay between rare and common variants may therefore contribute to the clinical profiles of the individuals carrying LoF in genes associated with ASD.

Environmental issues ,Science and technology ,Zoology and wildlife conservation - Abstract
Autism spectrum disorders comprise a range of neurodevelopmental disorders characterized by deficits in social interaction and communication, and by repetitive behaviour (1). Mutations in synaptic proteins such as neuroligins (2,3), neurexins (4), GKAPs/SAPAPs (5) and ProSAPs/ Shanks (6-10) were identified in patients with autism spectrum disorder, but the causative mechanisms remain largely unknown. ProSAPs/ Shanks build large homo- and heteromeric protein complexes at excitatory synapses and organize the complex protein machinery of the postsynaptic density in a laminar fashion (11,12). Here we demonstrate that genetic deletion of ProSAP1/Shank2 results in an early, brain-region-specific upregulation of ionotropic glutamate receptors at the synapse and increased levels of ProSAP2/Shank3. Moreover, ProSAP1/[Shank.sup.-/-] mutants exhibit fewer dendritic spines and show reduced basal synaptic transmission, a reduced frequency of miniature excitatory postsynaptic currents and enhanced JV-methyl-D-aspartate receptor-mediated excitatory currents at the physiological level. Mutants are extremely hyperactive and display profound autistic-like behavioural alterations including repetitive grooming as well as abnormalities in vocal and social behaviours. By comparing the data on ProSAP1/[Shank.sup.-/-] mutants with ProSAP2/ Shank3α[β.sup.-/-] mice, we show that different abnormalities in synaptic glutamate receptor expression can cause alterations in social interactions and communication. Accordingly, we propose that appropriate therapies for autism spectrum disorders are to be carefully matched to the underlying synaptopathic phenotype., Many of the recently identified autism spectrum disorders (ASD) candidate genes code for proteins of excitatory synapses (13-15), suggesting that these disorders may arise from molecular imbalances of synaptic connections.

Funder: Wellcome Trust (Wellcome); doi: https://doi.org/10.13039/100004440, Funder: Templeton World Charity Foundation (Templeton World Charity Foundation, Inc.); doi: https://doi.org/10.13039/501100011730, The substantial phenotypic heterogeneity in autism limits our understanding of its genetic etiology. To address this gap, here we investigated genetic differences between autistic individuals (nmax = 12,893) based on core and associated features of autism, co-occurring developmental disabilities and sex. We conducted a comprehensive factor analysis of core autism features in autistic individuals and identified six factors. Common genetic variants were associated with the core factors, but de novo variants were not. We found that higher autism polygenic scores (PGS) were associated with lower likelihood of co-occurring developmental disabilities in autistic individuals. Furthermore, in autistic individuals without co-occurring intellectual disability (ID), autism PGS are overinherited by autistic females compared to males. Finally, we observed higher SNP heritability for autistic males and for autistic individuals without ID. Deeper phenotypic characterization will be critical in determining how the complex underlying genetics shape cognition, behavior and co-occurring conditions in autism.

This paper aims at including in the stylistician’s tool-box possibly less familiar tools, borrowed from the scientific domains of chaos theory and neuroscience to develop a comprehensive analysis of literary texts. A close reading of Alice Munro’s “Day of the Butterfly” reveals the short-story to be a chaotic system, a dynamical, non linear system sensitive to initial conditions – to what is commonly known as the “butterfly effect”. Reading such texts involves tracing precise trajectories that fold and stretch along underlying structures called attractors in chaos theory. Literary discourse analysis leads to analyzing attractors in close connection with empathy, a notion whose infinite complexity is now being further revealed by the recent discoveries around mirror neurons and the role of mirror mechanisms in the way we relate to the “real” world and art. Although following the itineraries of complexity tends to produce more questions than answers, and leave the reader in a challenging state of uncertainty, it meaningfully echoes our experience of Alice Munro’s work.

A l’occasion du quarantième anniversaire de la SSA, ce travail se propose d’ajouter quelques nouveaux instruments d’exploration à la boîte à outils développée par Leech et Short (Style in Fiction, 1981) et de voir comment le paradigme de complexité peut permettre à la stylistique de se développer dans de nouvelles directions, prenant en compte des domaines aussi divers que la théorie du chaos et les découvertes en neurosciences. Cet article se veut également un hommage au nouvelliste William Trevor, récemment disparu ; une lecture de l’une de ses dernières nouvelles, « The Piano Teacher’s Pupil » sera proposée. This paper aims at adding a few tools to Leech and Short’s stylistic tool-box (Style in Fiction, 1981) and suggesting new directions for the development of stylistics, with a special interest for the way complexity, chaos theory and neuroscience might articulate with more traditional tools. Special attention will be devoted to one of William Trevor’s last stories, “The Piano teacher’s pupil”.

Sleep wake cycles are frequently disturbed in patients with Attention Deficit and Hyperactivity Disorders. We hypothesized that the origin of the sleep problems may be the consequence of an abnormal circadian clock setting regulated by the melatonin pathway. Here, we sequenced all the genes of the melatonin pathway AA-NAT, ASMT, MTNR1A, MTNR1B and GPR50 in 328 individuals from Sweden including 108 patients with ADHD and 220 from the general population. Non-synonymous mutations were identified in all genes at a similar frequency in patients with ADHD and in controls. Among the functional variations, a splice site mutation (IVS5+2T>C) in ASMT and one stop mutation (Y170X) in MTNR1A were only detected in patients with ADHD. Biochemical analyses indicated that these mutations abolish the activity of ASMT and MTNR1A. We also identified clusters of SNPs within MTNR1B showing significant difference in the allelic frequency between ADHD patients and control (maximum signal at rs10830961 P=0.0002). Taken together, these genetic and functional results shed light on one new compelling candidate pathway for susceptibility to circadian rhythms alterations that could help clinicians for providing better treatments of patients with ADHD and sleep problems.
