title: Significant variations of fingertip dermatoglyphics in trisomy 21, Down's syndrome.
abstract: In this study a new method for description of fingerprints was used on plain ulnar loops of Down's syndrome individuals of both sexes. The results of the patients were compared with those of their parents, siblings and unrelated control samples, all of the matching sex. Higher variability within the dermatoglyphics was seen among patients. The results were supported by higher correlation figures between the parameters studied in the control samples. The TRC showed no difference between Down's syndrome individuals and controls. Several causes for the results are discussed. Investigations by other authors are presented.
