The authors report a family with triphalangeal thumb with nail hypoplasia: one of them has also split feet. They believe that the existence of such families must make very circumspect with regard to genetic counseling for a minor problem such as triphalangeal thumb.
其中一人还患有足裂。他们认为，对于像三节拇指这样的小问题进行遗传咨询时，存在此类家族情况必须要非常谨慎。
