Hoarding, originally only considered a symptom of obsessive‐compulsive disorder (OCD), is now categorized as a separate disorder in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM‐5). We studied candidate serotonergic genes and the distinctness of hoarding in children and adolescents and hypothesized that unique gene variants would be associated with hoarding alone.

在基于人群的儿科样本中，血清素系统基因和囤积有无其他强迫症特征：遗传关联研究。
