Abstract

The similarity of IQs of siblings with Duchenne progressive muscular dystrophy (DMD) was examined to determine whether the view that downward shift in IQ of patients with DMD is a genetically determined primary manifestation of the disease. The mean IQ difference was smaller and the IQ correlation was higher for siblings with DMD than for siblings without the disease. Moreover, these two indices were closer to those for healthy monozygotic twins reared together. These results suggest that the lowered IQ in patients with DMD has a genetic background.

摘要

研究了患有杜氏进行性肌营养不良症（DMD）的兄弟姐妹的智商相似性，以确定DMD患者智商下降是该疾病由基因决定的主要表现这一观点是否正确。与未患该病的兄弟姐妹相比，患DMD的兄弟姐妹的平均智商差异更小，智商相关性更高。此外，这两个指标更接近一起抚养的健康同卵双胞胎的指标。这些结果表明，DMD患者智商降低具有遗传背景。
