Abstract

BACKGROUND: There are controversial evidences on the association between fingerprint traits and schizophrenia. Wecompared fingerprint traits of patients with schizophrenia and normal individuals in Iranian population.METHODS: Finger tip dermal ridge of 290 patients with schizophrenia and 290 normal subjects were studied for fourdermal traits. Data was analyzed with Pearson correlation and t-student tests.RESULTS: Finger print patterns and secondary creases were not significantly different between the two groups (p > 0.05).Although mean ridge counts of left and right index fingers of the case group were greater than the control group (p < 0.05),these differences were not significant in females.CONCLUSIONS: Probably the left index ridge counts and fluctuating asymmetry in schizophrenic patients are differentfrom those of the normal population. This difference may serve as a diagnostic biological marker for screening peoplesusceptible to schizophrenia. Further studies are needed to determine predictive value of fingerprint trait as a biomarkerfor the schizophrenia.
