The aim of this study was to investigate if Iranian individuals with nonfamilial cleft lip and palate (CLP) and their unaffected parents display more dermatoglyphic asymmetry than the normal population.

The study group included 55 patients with nonfamilial CLP and their unaffected parents (38 fathers and 47 mothers). The control group included 60 healthy children and their parents (37 fathers and 50 mothers). Total ridge counts of each finger (TRC), atd angles, a-b ridge counts, and finger print pattern types of all participants were recorded. Asymmetry between the right and left hands of each individual was determined. Dissimilarity between pattern types on homologous fingers was compared using chi-square test. Asymmetry of other parameters was statistically analyzed using the Mann-Whitney U test.

There were no significant differences between the groups in terms of their asymmetry of atd angle, a-b ridge count, and pattern dissimilarity score. However, significant differences in mean TRC between CLP patients and control children were found for the right ring digit (P = 0.023), right little digit (P = 0.032), and left index digit (P = 0.005). Also, there were significant differences among CLP patients and control children (P = 0.022) as well as unaffected fathers of CLP patients and their control group (P = 0.020) in terms of type of finger print pattern.

No enhanced fluctuating asymmetry was found in most of the dermatoglyphic traits in the population studied, which indicated a low degree of developmental instability of the sporadic cases of cleft deformity.
