This paper shows that the study of dermatoglyphics is an objective aid in the clinical diagnosis of chromosomal dysmorphic syndromes. The dermatologlyphic patterns of four patients with trisomy 9p were analyzed and compared with dermatoglyphic data from 63 published case reports on the condition. We consider that the following traits constitute the combination of dermatoglyphic patterns that is specific to trisomy 9p: an excess of arches on the fingertips and toes, a low total finger ridge count, the absence of digital triradii b and c, and the presence of zygodactylous triradii z, z' and z'', a simian crease, a single crease on the 5th finger, a hypothenar crease, a distally placed axial triradius t', a proximal or tibial arch or both on the hallux, and increased intensity of the plantar patterns. A "phantom picture" is constructed, which can be used for dermatoglyphic diagnosis of the trisomy 9p syndrome.
本文表明，皮纹学研究是染色体发育异常综合征临床诊断的一种客观辅助手段。分析了4例9p三体患者的皮纹模式，并与63篇已发表的关于该病症的病例报告中的皮纹数据进行了比较。我们认为，以下特征构成了9p三体特有的皮纹模式组合：指尖和脚趾上弓形纹过多、总指嵴数低、无b和c指三叉点、存在对掌三叉点z、z'和z''、猿线、第5指单褶、小鱼际褶、远位轴三叉点t'、拇趾上近端或胫侧弓形纹或两者皆有，以及足底纹强度增加。构建了一幅“虚拟图像”，可用于9p三体综合征的皮纹诊断。
