An infant born without toenails and without the middle and distal phalanges of the toes was otherwise normal, on clinical and radiological examination. This is the second case of this entity to be described. It is speculated that an environmental insult at the critical period of fetal toe development may be the cause of the anomaly, but a genetic factor cannot be excluded.
一名出生时没有脚趾甲且没有中节和远节趾骨的婴儿，经临床和放射学检查，其他方面均正常。这是该病症被描述的第二例病例。据推测，胎儿脚趾发育关键期受到的环境损害可能是该异常的原因，但也不能排除遗传因素。
