An accurate description of nail changes in congenital and hereditary conditions is complicated both by vague terminology and by errors introduced by the effects of trauma. This article attempts to identify primary developmental abnormalities in the nails and divides them into those caused by defects in the nail matrix, the nail field, or the nail bed and those originating from combined ectodermal and mesodermal defects. Attempting to identify underlying embryological defects may allow a more logical approach to both description and classification of congenital and hereditary nail abnormalities.
由于术语模糊以及创伤影响所导致的错误，准确描述先天性和遗传性疾病中的指甲变化变得复杂。本文试图识别指甲的原发性发育异常，并将其分为由甲母质、甲床或甲襞缺陷引起的异常，以及源自外胚层和中胚层联合缺陷的异常。试图识别潜在的胚胎学缺陷可能会为先天性和遗传性指甲异常的描述和分类提供一种更合理的方法。
