Abstract

While schizophrenia (SCZ), bipolar disorder (BD) and major depressive disorder (MDD) genetically correlate, the pleiotropy underlying response/resistance to drugs used in these disorders has not been investigated. The aim of this study is to analyze the genetic relationship between treatment-resistant schizophrenia (TRS), response to lithium in BD (respLi) and response to antidepressants in MDD (respAD) using the conditional/conjunctional false discovery rate (cond/conjFDR) methodology, based on the hypothesis that shared mechanisms related to a common psychopathology factor underlie these phenotypes. A cross-trait polygenic enrichment for TRS conditioned on associations with respLi was observed. The conjFDR analysis identified rs11631065 (chr15:66654304) as a shared locus between them. One of the genes at this locus is MAP2K1, previously reported as associated with TRS after conditioning on body mass index genome-wide association study (GWAS). The set of genes at TRS-respLi conjFDR < 0.95 showed enrichment in response to psychotropic drugs in severe mental disorders from GWAS Catalog as well as in neurodevelopment and synaptic pathways. In conclusion, our study constitutes the first evidence of a transdiagnostic genetic signal associated with response to different pharmacological treatments in psychotic and affective disorders. It is necessary to confirm these results when larger GWAS of these phenotypes are available.

严重情感障碍和精神病治疗反应的共同多基因易感性:来自 GWAS 数据集的证据
虽然精神分裂症(SCZ)、双相情感障碍(BD)和重度抑郁障碍(MDD)在遗传学上存在相关性,但这些疾病对药物的反应/耐药性背后的多向性尚未得到研究。本研究的目的是利用条件/联合假发现率(cond/conjFDR)方法分析耐药精神分裂症(TRS)、BD 患者对锂盐的反应(respLi)和 MDD 患者对抗抑郁药的反应(respAD)之间的遗传关系,其假设是这些表型是由与共同精神病理学因素相关的共享机制造成的。在与 respLi 相关的条件下,观察到 TRS 的跨性状多基因富集。conjFDR分析确定了rs11631065(chr15:66654304)是它们之间的共享位点。该基因位点上的一个基因是 MAP2K1,以前曾有报道称该基因与体重指数全基因组关联研究(GWAS)相关。在 TRS-respLi conjFDR < 0.95 处的基因集显示,GWAS 目录中的严重精神障碍患者对精神药物的反应以及神经发育和突触通路都有富集。总之,我们的研究首次证明了跨诊断遗传信号与精神病和情感障碍患者对不同药物治疗的反应有关。有必要在对这些表型进行更大规模的 GWAS 研究时证实这些结果。

期刊介绍: Progress in Neuro-Psychopharmacology & Biological Psychiatry is an international and multidisciplinary journal which aims to ensure the rapid publication of authoritative reviews and research papers dealing with experimental and clinical aspects of neuro-psychopharmacology and biological psychiatry. Issues of the journal are regularly devoted wholly in or in part to a topical subject. Progress in Neuro-Psychopharmacology & Biological Psychiatry does not publish work on the actions of biological extracts unless the pharmacological active molecular substrate and/or specific receptor binding properties of the extract compounds are elucidated.
