A family pedigree containing sixteen individuals with acute appendicitis is presented. In all but one the position of the appendix was retrocecal. In two other members explored for abdominal pain wherein acute appendicitis was not the cause, the appendix was also found to be retrocecal. The anatomic retrocecal location of the appendix in this pedigree shows a degree of uniformity that implies a common predisposing factor inherited as a simple, dominant unit-character.
本文展示了一个包含16例急性阑尾炎患者的家系图谱。除1例之外，其余所有患者的阑尾位置均在盲肠后。另外2例因腹痛接受检查但并非由急性阑尾炎所致的家系成员，其阑尾位置也在盲肠后。该家系图谱中阑尾在解剖学上的盲肠后位置显示出一定程度的一致性，这意味着存在一个作为简单显性单位性状遗传的共同易感因素。
