PROJECT SUMMARY The International Consortium on Brain and Behavior Copy Number Variants (IBBC-CNVs) is a collaborative effort of 9 institutions with complementary experience and expertise in phenomics and genomics. The 22q11.2 and 16p11.2 loci are associated with significant risk for neuropsychiatric disorders across the lifespan. The clinical presentations are heterogeneous, manifesting in a range of developmental neuropsychiatric disorders, including Attention Deficit Hyperactivity, Anxiety, Autism Spectrum, and Psychosis Spectrum Disorders. Taking a ‘genetics first’ approach of ascertaining patients based on known, homogeneous genetic etiologies will allow us to overcome barriers posed by the genetic and phenotypic complexity of idiopathic developmental neuropsychiatric disorders. We postulate that CNVs exert a large main effect on psychopathology, but the nature and degree of psychopathology observed in CNV carriers is multifactorial, with contributions from additional rare and common genetic variants, as well as environmental factors. Therefore, dissecting the effects of major CNV hits as well as additional rare and common variants on dimensional measures of psychopathology can elucidate the combined contribution of genetic mechanisms to psychiatric conditions and build models of risk prediction. Notably, the presentation and course of psychopathology in the CNVs resemble these features in idiopathic disorders. Therefore, beyond the specific genetic syndromes investigated, such a cross-CNV effort will identify convergent risk mechanisms for developmental neuropsychiatric disorders that are of relevance to the broader population. We propose to dissect dimensional measures of psychosis, social-emotional processing and neurocognition, and their genetic and environmental modifiers, to elucidate the architecture of risk for neuropsychiatric disorders in CNV carriers. Prospective evaluation with dimensional measures relevant to neuropsychiatric disorders will be applied to a cohort of 2000 individuals with 22q11.2 and 16p11.2 deletions and duplications (500 per group) and their relatives as feasible. In addition, categorical psychiatric diagnoses will be assessed in CNV carriers. Recruitment for prospective phenotyping will leverage existing large cohorts that carry these reciprocal CNVs, many of whom have already been ascertained and characterized with a range of phenotypic measures. New whole genome sequencing (WGS) will be performed in CNV carriers that have not yet been sequenced. We will also utilize existing genetic data from the largest available case-control samples diagnosed with SZ, ASD, and ADHD in the PGC to generate polygenic risk scores. Finally, we will examine family and environmental factors that contribute to the heterogeneity of presentation and developmental course in CNV carriers. This project will establish common phenomic and genomic resources. Our ability to conceive such a large-scale study capitalizes on our existing successful collaborations, complementary expertise, and institutional commitments to achieve these goals.

项目概要 国际脑与行为拷贝数变异联盟 (IBBC-CNVs) 是一个协作组织 9 个在表型组学和基因组学方面具有互补经验和专业知识的机构的努力。 22q11.2 和 16p11.2 位点与整个生命周期中神经精神疾病的显着风险相关。 临床表现多种多样，表现为一系列发育性神经精神疾病， 包括注意力缺陷多动症、焦虑症、自闭症谱系障碍和精神病谱系障碍。 基于已知的同质遗传病因来确定患者的“遗传学优先”方法将允许 我们克服特发性发育的遗传和表型复杂性所造成的障碍 我们假设 CNV 对精神病理学有很大的影响，但 在 CNV 携带者中观察到的精神病理学的性质和程度是多因素的，其中的贡献来自于 其他罕见和常见的遗传变异，以及环境因素，因此，剖析。 主要 CNV 命中以及其他罕见和常见变异对维度测量的影响 精神病理学可以阐明遗传机制对精神疾病的综合作用， 值得注意的是，CNV 中精神病理学的表现和过程与此类似。 因此，除了研究的特定遗传综合征之外，还存在特发性疾病的这些特征。 跨 CNV 的努力将确定发育性神经精神疾病的趋同风险机制，这些疾病 与更广泛的人群相关。 我们建议剖析精神病、社会情感处理和神经认知的维度测量， 及其遗传和环境调节剂，以阐明神经精神疾病的风险结构 使用与神经精神相关的维度测量对 CNV 携带者的疾病进行前瞻性评估。 该疾病将应用于 2000 名 22q11.2 和 16p11.2 缺失和重复个体的队列 （每组 500 人）及其亲属（如果可行）还将评估明确的精神病学诊断。 CNV 携带者的招募将利用现有的携带这些基因的大型群体。 相互的 CNV，其中许多已被确定并具有一系列表型特征 新的全基因组测序（WGS）将在尚未进行的 CNV 携带者中进行。 我们还将利用来自最大的可用病例对照样本的现有遗传数据。 在 PGC 中诊断患有 SZ、ASD 和 ADHD，以生成多基因风险评分。 导致表现和发展过程异质性的家庭和环境因素 该项目将建立我们的受孕能力。 如此大规模的研究利用了我们现有的成功合作、互补的专业知识和 实现这些目标的机构承诺。
