The Palmar Dermatoglyphic Patterns in Type II Diabetes Mellitus Cases- A Study in South Indian Population

Abstract

Diabetes mellitus [DM] is a major disease worldwide with increasing prevalence. Its etiologic heterogeneity comprising genetic predisposition and environmental factors may provide a characteristic feature among the population helpful for the early diagnosis. This study aims to evaluate the palmar dermatoglyphic patterns in DM patients. This case controlled cross-sectional study included 100 type 2 DM patients in group A and 100 healthy subjects in group B. Each group has equal gender distribution. The palmar dermatoglyphics were evaluated quantitatively using standard methods. Student’s t-test and Chi-square test was used to determine the level of significance. The palmar triradius number varied significantly (Pd”0.0001). The angle of palm variations were statistically insignificant between groups, but TAD angle showed significant gender variations in group A patients (Pd”0.0001). The variation in palmar triradius revealed in this study may help in early diagnosis of type 2 DM patients and also may provide a scope for further studies with larger sample size.
