[Bilateral symmetry of the dermatoglyphic characteristics in Down's syndrome].

Dermatoglyphic traits were analyzed in 132 patients with Down syndrome. The level of bilateral symmetry of dermatoglyphic indices in these patients was found to be higher than in normal people (control). By this parameter, patients with Down syndrome showed lower intragroup variation than the control group. It is suggested that such difference is due to a more primitive developmental pathway.
