理论和研究都指出,表观遗传过程同时影响着育儿行为和孩子的功能。然而,人们对母亲和孩子在家庭中的表观遗传模式的趋同知之甚少。因此,目前的研究调查了四个压力调节相关基因(5HTT、NR3C1、FKBP5和BDNF)母子二元组甲基化水平的表观遗传协方差。协方差检验在一般人群样本中进行,包括早期青少年(MAGE=11.63,SDAGE=2.3)和母亲(N=160对)。结果表明,母子代5HTT和NR3C1甲基化模式相关。此外,当跨基因平均化时,甲基化水平之间存在很强的相关性。这些发现部分支持孩子和父母的甲基化水平不同。考虑这种协方差对于理解不适应的亲子关系可能很重要。
Theory and research both point at epigenetic processes affecting both parenting behavior and child functioning. However, little is known about the convergence of mother and child’s epigenetic patterns in families. Therefore, the current study investigated epigenetic covariance in mother–child dyads’ methylation levels regarding four stress-regulation related genes (5HTT, NR3C1, FKBP5, and BDNF). Covariance was tested in a general population sample, consisting of early adolescents (Mage = 11.63, SDage = 2.3) and mothers (N = 160 dyads). Results showed that mother and offspring 5HTT and NR3C1 methylation patterns correlated. Furthermore, when averaged across genes, methylation levels strongly correlated. These findings partially supported that child and parent methylation levels covary. It might be important to consider this covariance to understand maladaptive parent–child relationships.
