背景:Catatonia是一种未被认识到的疾病,其特征是精神运动性(增加,减少,或异常)变化,情感症状,和意志的干扰,这可能出现在失代偿性精神病或非精神病医学疾病的背景下。对紧张症的遗传研究是有限的,据我们所知,迄今为止还没有进行过卡托尼亚的全基因组关联研究。
方法:首先,我们进行了全基因组关联研究,无论病因(精神病或非精神病)。其次,我们评估了易感精神疾病(精神分裂症谱系障碍,双相情感障碍,等。)在紧张症患者中。我们使用了匹配的病例对照设计,并应用了多基因风险评分来评估常见的精神病表型对卡顿多症的共同多遗传贡献,这些表型在失代偿状态下显示出卡顿多症的患病率很高。
结果:焦虑,双相情感障碍,精神分裂症谱系障碍和交叉障碍多基因风险评分在欧洲祖先组的未调整和调整逻辑回归模型中与卡顿多症病例状态显着相关,即使在校正多重比较后也是如此。抑郁症,老年痴呆症,孤独症谱系障碍和强迫症多基因风险评分与欧洲祖先参与者的紧张症状态没有显着相关。在非洲祖先布景中,在未校正或校正回归模型中,精神病多基因风险评分与紧张症状态无显著相关.
结论:即使在控制相关协变量后,焦虑,双相情感障碍,精神分裂症谱系障碍和交叉障碍与紧张症状态显着相关,这表明紧张症患者之间可能存在这些疾病的共同遗传风险。
BACKGROUND: Catatonia is an under-recognized disorder characterized by psychomotor (increased, decreased, or abnormal) changes, affective symptoms, and disturbance of volition, which may arise in the setting of decompensated psychiatric or non-psychiatric medical disorders. Genetic studies of catatonia are limited, and to the best of our knowledge no prior genome wide association studies of catatonia have been performed to date.
METHODS: First we performed a genome wide association
study of catatonia regardless of etiology (psychiatric or non-psychiatric). Secondarily we evaluated whether there was an elevated genetic risk profile for predisposing psychiatric disorders (schizophrenia spectrum disorder, bipolar affective disorder, etc.) in patients with catatonia. We used a matched case control design and applied polygenic risk scores to evaluate for a shared polygenetic contribution to catatonia from common psychiatric phenotypes that show a high prevalence of catatonia in their decompensated states.
RESULTS: Anxiety, bipolar affective disorder, schizophrenia spectrum disorder and cross disorder polygenic risk scores were significantly associated with catatonia case status in both unadjusted and adjusted logistic regression models for the European Ancestry set even after correcting for multiple comparisons. Depression, Alzheimer\'s, Autism Spectrum Disorder and Obsessive Disorder polygenic risk scores were not significantly associated with catatonia status in participants of European Ancestry. In the African Ancestry set, no psychiatric polygenic risk scores were significantly associated with catatonia status in either the unadjusted or adjusted regression models.
CONCLUSIONS: Even after controlling for relevant covariates, anxiety, bipolar affective disorder, schizophrenia spectrum disorder and cross disorders were significantly associated with catatonia status suggesting that there might be a shared genetic risk for those disorders amongst patients with catatonia.
