Absent d triradii were found in 2 sibs of a family of African ancestry. 1 of the sibs exhibited not only bilateral absence of d triradius but also bilateral absence of axial triradii. The other sib lacked d triradius in the left palms. All 5 sibs of the sibship showed, to some degree, dotting or dissociation of the ridges. The present results support the suggestion of genetic transmission of both absent d triradius and dotting of the ridges.
在一个非洲裔家庭的两名同胞中发现了d三叉点缺失。其中一名同胞不仅双侧d三叉点缺失，还双侧轴三叉点缺失。另一名同胞左手掌缺少d三叉点。该同胞关系中的所有五名同胞在某种程度上都表现出嵴纹的点纹或分离。目前的结果支持d三叉点缺失和嵴纹点纹均由基因传递的观点。
