Hereditary aspects in the anomalous innervation of the extensor digitorum brevis muscle by the accessory deep peroneal nerve, were investigated. Utilizing electrophysiological techniques, 22% of 100 healthy unrelated individuals demonstrated this variation in innervation of one or both extensor digitorum brevis muscles. The study of family members of five of these subjects with the variation showed that 78% of relatives also had this anomalous innervation. These data suggest that hereditary factors may be significant in the occurrence of this variation and a dominant mode of inheritance may be the case.
研究了腓深副神经对趾短伸肌异常支配的遗传因素。利用电生理技术，在100名健康无亲属关系的个体中，22%的人表现出一侧或双侧趾短伸肌神经支配的这种变异。对其中5名有这种变异的受试者的家庭成员进行研究发现，78%的亲属也有这种异常神经支配。这些数据表明，遗传因素可能在这种变异的发生中起重要作用，且可能为显性遗传模式。
