To investigate whether the phenotypic resemblance of Down's syndrome patients of different racial origins extended to include their dermatoglyphic characteristics, we made comparisons of dermal pattern frequencies on digits, palms, and hallucal areas of white, black and Japanese patients and matched controls. The results showed similarities in frequencies of digital whorls and ulnar loops in patients of all racial groups, of patterns in hallucal, thenar/I, second and third interdigital areas in white and black patients, and of hypothenar patterns and t" triradii in Japanese and black patients. The frequencies of the digital arches and remainder of the palmar configurations in patients of three racial groups showed significant, though often smaller, differences than those found in their controls.
为了研究不同种族来源的唐氏综合征患者的表型相似性是否扩展到包括他们的皮纹特征，我们对白人、黑人和日本患者以及匹配的对照组的手指、手掌和拇趾区域的皮肤纹路频率进行了比较。结果显示，所有种族组患者的指螺和尺侧箕频率相似，白人和黑人患者的拇趾、鱼际/I、第二和第三指间区域的纹路相似，日本人和黑人患者的小鱼际纹路和t”三叉点相似。三个种族组患者的指弓频率和手掌其余构型与各自对照组相比存在显著差异，尽管差异通常较小。
