Abstract

1 – 35 male and 37 female and a total of 72 Down’s Syndrome cases dermal patterns were studied. These were compared with those of 212 male and 191 female children.

2 – In Down’s Syndrome cases ulnar loop patterns on all fingertips and loop type dermal patterns on the fourth and fifth fingers increased.

3 – No important statistical difference was established in the fingertip ridge count between Down’s Syndrome and control cases.

4 – Fewer a-b ridges exist on the palms in Down’s Syndrome cases than those in control cases.

5 – In the third interdigital area more distal loops exist in Down’s Syndrome cases than those in control cases.

6 – Atd angles and t percentages are greater in Down’s Syndrome cases.

7 – Simian line and single flexion line on the fifth finger are frequently observed in Down’s Syndrome cases.

8 – In hallucal areas of Down’s Syndrome cases tibial arch or narrow distal loop patterns are frequent.
