概括

这项研究确定了儿童注意力缺陷/多动症 (ADHD) 血细胞中的特定DNA甲基化模式. 这些在婴儿和儿童血液中发现的表观遗传标记可能表明ADHD风险.

科学领域:

表观遗传学在表观遗传学中,表观遗传学是指表观遗传学.
神经发育障碍神经发育障碍
基因组学就是基因组学.

背景情况:

注意缺陷/多动障碍 (ADHD) 是一种复杂的神经发育障碍,疑似具有表观遗传基础.
之前的DNA甲基化 (DNAm) 研究主要使用了大量组织,限制了细胞类型特定的见解.
了解ADHD的基因调节对于识别潜在的生物标志物和治疗点至关重要.

研究的目的:

为了识别与儿童多动症症状相关的细胞类型特定的DNA甲基化概况.
在外周和带血液中进行全甲基组关联研究 (MWAS) 的元分析.
在ADHD表观遗传学中探索统计解卷和基于测序的方法的实用性.

主要方法:

利用统计解卷方法分析5种主要血细胞类型的DNAm.
在多个队伍中对MWAS进行了元分析 (怀孕和童年表观遗传学联盟,大烟雾山研究).
采用了基于阵列 (450K CpGs) 和基于测序 (28M CpGs) 的甲基化数据.

主要成果:

在CD8T细胞 (周围血液) 和单细胞,CD8T细胞和NK细胞 (带血) 中确定了ADHD相关的DNAm位点.
在外围和带血液中发现重叠的显著DNAm位点 (RPL31P11,KCNJ5).
在GSMS队列中扩展的MWAS在单细胞和粒细胞中发现了额外的CpG.

结论:

这是ADHD的第一个细胞类型特定的MWAS,揭示了新的DNAm与儿童ADHD症状的关联.
确定了潜在的表观遗传敏感性标志物,用于从出生时就存在的ADHD风险.
强调细胞类型特定分析和高分辨率甲基化数据对于推动ADHD研究的重要性.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Human Genetics

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Epigenetic Regulation

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
