Introduction: Introduction: Dermatoglyphics is the study of epidermal ridges and their configurations on the fingers, palms and soles. They can be considered as the blueprint of the activities that occurred during fetal life. They reflect the neurectodermal changes that were taking place in-utero as early as 12th week. Application of dermatoglyphic pattern as a genetic marker in schizophrenia has attracted the attention of many researchers in the world. Various studies have been conducted to prove the direct link between ridges on epidermis and schizophrenia using different features to characterize the configuration of ridges.
Aim: To study and compare dermatoglyphic patterns of schizophrenic patients with control population.
Materials and Methods: The study was conducted on 100 schizophrenics and 100 controls. The palms of the control and study groups were inked and pressed on plain paper. The obtained palm prints were studied namely finger print patterns and palmar pattern (a-bridge count, interdigital patterns), Total Finger Ridge Count (TFRC), Absolute Finger Ridge Count (AFRC), and mean ‘atd’ angle.
Results: TFRC and a-b ridge count was decreased in schizophrenics (117.01 with SD of 31.5) when compared to controls (117.18 with SD of 35.6), though the difference was statistically not significant (p=0.972). Mean ab-RC in right hand of schizophrenics was lower (29.69) with SD of 6.7 as compared to control group which was having ab-RC of 35.72 with SD of 6.2. This difference was statistically highly significant (p<0.001). Mean ab-RC in left hand of schizophrenics was lower (30.32) with SD of 6.2 as compared to control group which was having ab-RC of 35.94 with SD of 5.9 This difference was statistically highly significant (p<0.001). Frequency of occurrence of patterns in interdigital areas in schizophrenia was compared with control group- more patterns seen in I3 and I4 areas, but data was statistically significant only at I2.
Conclusion: Therefore, this study demonstrated that certain dermatoglyphic patterns (ab-RC) are associated with schizophrenia and potential utility of these dermatoglyphic patterns in identifying individuals at high risk for schizophrenia may be considered in future studies.
