BACKGROUND Several studies have reported alterations in finger and a-b ridge counts, and their derived measures of asymmetry, in schizophrenia compared to controls. Because ridges are fully formed by the end of the second trimester, they may provide clues to disturbed early development. The aim of this study was to assess these measures in a sample of patients with psychosis and normal controls...

Various dermatoglyphic parameters like finger print pattern, atd angle, absolute ridge count & ab, bc ,cd, and ad ridge counts were observed in 150 cases of congenital cardiac disease, comprising of 72 cases of Ventricular Septal Defects (VSD), 60 cases of Atrial Septal Defects (ASD), 9 cases of Coarctation of Aorta (COA) & 9 cases of Tetralogy of Fallot's (TOF). Same dermatoglyphic parameters ...

BACKGROUND There are controversial evidences on the association between fingerprint traits and schizophrenia. We compared 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 four dermal traits. Data was analyzed with Pearson correlation and st...

The study of dermal ridges in schizophrenia has been extensive, but only recently has fluctuating asymmetry been described. This study relates dermatoglyphic patterns with the specific positive and negative symptoms of the disease in 72 DSM-III-R defined schizophrenia and 72 normal unrelated ethnically matched controls. Schizophrenic subjects had significant lower ridge counts in both hands. Fl...

Autism is a neurodevelopmental disorder originating from early childhood; nevertheless, its diagnosis is in older ages. In addition to heredity, environmental factors are also of great significance in the etiology of the disease. Dermatoglyphic patterns, albeit varied, remain stable for a lifetime and yield a large number of patterns upon examination. Studies have shown a significant associatio...

OBJECTIVE To examine dermatoglyphic features to clarify implicated genetic predisposition in the etiology of multiple sclerosis (MS). METHODS The study was conducted between January and December 2013 in the Departments of Anatomy, and Neurology, Cumhuriyet University School of Medicine, Sivas, Turkey. The dermatoglyphic data of 61 patients, and a control group consisting of 62 healthy adults ...

Distributions, correlations and weighted least squares estimates of the components of variation in right-left asymmetry for individual finger ridge counts have been obtained from 221 pairs of twins and 80 pairs of opposite sex siblings. Asymmetry has been measured by two indices: signed right-left difference representing unidirectional asymmetry and absolute difference, representing ambidirecti...

1. The genetical and environmental structure of covariation between finger ridge counts in twin and sibling data has been analysed using the method of Martin and Eaves (1977) adapted from Jöreskog. 2. The model for environmental covariance contains a single factor loading on all ten digits but most environmental variance is specific to each finger. 3. For additive genetic variance there is one ...
