title: Down's syndrome in Nigeria: dermatoglyphic analysis of 50 cases.
abstract: Dermatoglyphic analysis was carried out on 50 cases of Down's Syndrome and 100 normals. It involved the digital patterns, axial triradius and palmer crease on the hands. 94.6% of the digital patterns in Down's Syndrome were the Ulnar loop type against 62.5% in the normals. No arch was reported in Down's Syndrome. There were more whorl patterns in the normals (31.1%) than in the Down's Syndrome group (4%). The mode of the distribution of the digital indices in the Down's Syndrome was at +3.58. More than 84% of the 50 cases of Down's Syndrome have digital index of +3.58 compared to only 12% in the normals.
