Abstract

Younger siblings of children with ASD often exhibit elevated internalizing and externalizing problems. We investigated common dopaminergic variants (DRD4 and DRD2) in relation to behavior problems at 36 months. Genotypes linked to less efficient dopaminergic functioning were associated with higher internalizing problems in high-risk siblings.

摘要

患有自闭症谱系障碍(ASD)儿童的年幼兄弟姐妹往往表现出更多的内化和外化问题。我们研究了常见的多巴胺能基因变体(DRD4和DRD2)与36个月大时行为问题的关系。与多巴胺能功能效率较低相关的基因型与高危兄弟姐妹中较高的内化问题有关。
