The dermatoglyphs of 13 Japanese (eight males and five females) with duplication of the thumb were studied. The dermal patterns on the thumb were compared with those on the extra digit. A whorl on the thumb was associated with a whorl on the extra digit in two cases, a radial loop in four cases, and an arch in two cases. Where the thumb pattern was a loop the pattern on the extra digit was a loop in all three cases. Where the thumb and extra digit are both well developed the pattern tends to be the same on both digits. When the extra digit is poorly developed it tends to have a different pattern from the thumb.
对13名患有拇指重复畸形的日本人（8名男性和5名女性）的皮纹进行了研究。将拇指上的皮纹图案与多指上的图案进行了比较。在两例中，拇指上的斗形纹与多指上的斗形纹相关，四例中与桡侧箕形纹相关，两例中与弓形纹相关。当拇指图案为箕形纹时，在所有三例中多指上的图案均为箕形纹。当拇指和多指均发育良好时，两者的图案往往相同。当多指发育不良时，其图案往往与拇指不同。
