阅读障碍是一种复杂的学习障碍,有证据表明有遗传基础。可能有助于剖析其遗传基础的策略包括组分表型的研究,这可以简化潜在的遗传复杂性,并使用分析方法,解释性状的多位点性质,以指导调查并增加检测单个位点的能力。在这里,我们提出的拼写残疾作为一个组成表型的遗传分析结果。拼写障碍在扩展谱系的分析中是有用的,因为它持续到成年。我们发现,少量的假设位点足以解释我们的样本中的性状的遗传,并且这些位点中的每一个都映射到四个基因组区域中的一个。个人特质模型和位置是一个功能,是否包括口头智商调整,建议调解通过智商相关和不相关的途径。
Dyslexia is a complex learning disability with evidence for a genetic basis. Strategies that may be useful for dissecting its genetic basis include the study of component phenotypes, which may simplify the underlying genetic complexity, and use of an analytic approach that accounts for the multilocus nature of the trait to guide the investigation and increase power to detect individual loci. Here we present results of a genetic analysis of spelling disability as a component phenotype. Spelling disability is informative in analysis of extended pedigrees because it persists into adulthood. We show that a small number of hypothesized loci are sufficient to explain the inheritance of the trait in our sample, and that each of these loci maps to one of four genomic regions. Individual trait models and locations are a function of whether a verbal IQ adjustment is included, suggesting mediation through both IQ-related and unrelated pathways.
