Members of the immediate families of twenty children with specific reading disability were examined to determine the prevalence of reading disability within the families. A procedure was developed for identifying adults who may have compensated for a disability manifested more clearly in childhood. Forty-five percent of 75 first-degree relatives of the parents were affected and there was a significantly greater number of affected male relatives than females. No single mode of genetic transmission is evident after inspection of the pedigrees. It is suggested that the disorder is genetically heterogeneous and that subgroups of disabled readers should be looked for.
对20名患有特定阅读障碍儿童的直系家庭成员进行了检查，以确定家庭中阅读障碍的患病率。开发了一种程序来识别那些可能已经弥补了在童年时期更明显表现出的残疾的成年人。父母的75名一级亲属中有45%受到影响，受影响的男性亲属数量明显多于女性。检查家谱后，没有明显的单一遗传传递模式。有人认为，这种疾病在遗传上是异质性的，应该寻找阅读障碍者的亚组。
