[Results of dermatoglyphic studies in the Roussy-Lévy syndrome].

Dermatoglyphics performed on the three persons with fully developed RLS as well as on those with partial symptomatology revealed a striking agreement as to their pappilary systems and the characteristic deviation from the norm: irregularities on the pattern of the ridges of the finger and toe prints and on the soles and palms, a much reduced "total ridge count" (TRC), predominant bow patterns on the toe prints, grid-and reticularpatterned white lines on the soles and palms, loop proliferation on the soles and special shapes of the transverse palmar crease.
