(International Journal of Applied Biological Research, 2011-07-14) Sanyaolu, A.O.; Oremosu, A.A.; Duru, F.I.O.; Noronha, C.C.; Olabiyi, O.; Okanlawon, A.O.
Studies of selected traits were undertaken to determine the occurrence of dermatoglyphics in autistics as compared with the normal children in Lagos state. Finger and palm prints were taken from 22 autistic children and 22 normal children. Quantitative and qualitative analysis of the traits, descriptive statistics, t test (p <0.05) and χ² (p<0.001), showed a significant difference in digital pattern types between autistic and normal children, but no significant difference in the total mean ridge count. Deferences in arches were not statistically significant. The total ridge count on both hands of autistic children is higher than in the normal. The atd (axial triradius) angle and a-b (distance between a triradius and b triradius) ridge count are higher in normal than in the autistic children. It was concluded that there is evidence to suggest the presence of definite dermatoglyphic features associated with autistic children compared to normal children.
