EN： In genetic research, particularly in developmental disorder studies, the terms 'trio', 'duo', and 'singleton' have specific technical meanings. A 'trio' refers to a genetic sample consisting of the affected individual (proband) and both biological parents. A 'duo' consists of the proband and only one parent, while a 'singleton' refers to the proband alone. Analyzing trios is highly valued in genomics as it allows researchers to easily identify de novo (new) mutations by comparing the child's DNA directly with both parents.
中文： 在遗传学研究中，特别是在发育障碍研究中，「trio（三人组）」、「duo（双人组）」和「singleton（单人组）」具有特定的技术含义。「trio」是指由受影响的个体（先证者）及其亲生父母双方组成的基因样本；「duo」由先证者和仅一方家长组成；而「singleton」则仅指先证者本人。在基因组学中，分析三人组（trios）具有极高的价值，因为它允许研究人员通过直接将孩子的 DNA 与父母双方进行对比，从而轻松识别出新生（de novo）突变。
