Pedigree analysis and dermatoglyphic features of probands with schizophrenia and their affected gender-matched parents: A cross-sectional comparative study.

ABSTRACT:

Background

The role of sex chromosomes in transmission of schizophrenia may be revealed by studies of phenotypic characteristics.

Aim

To explore variations in dermatoglyphic parameters between probands with schizophrenia and their respective affected gender-matched parents, with unaffected controls.

Methods

The difference of the absolute finger ridge counts (AFRC) and occurrence of identical finger patterns between the male probands and their affected fathers (n = 12) was compared with that of female probands and their affected mothers (n = 15). Similar comparisons were done between patients and unaffected child-parent pairs.

Results

The mean AFRC difference between right middle fingers of female probands and their affected mothers was less (3.47) than the mean
