Abstract

Objective:

The objective of this study was to correlate dermatoglyphics and cheiloscopy with genetic inheritance in cleft lip and cleft palate patients.

Design and Setting:

This was a case-control study to look for asymmetry in finger and lip print patterns. All of the participants were divided into two equal groups (40 mothers and 40 fathers in each group). The data were analyzed by three evaluators who were blind to the study to avoid any chances of error.

Patients/Participants:

A sample of 160 sporadic participants were identified and evaluated. Group A was composed of 80 healthy parents not affected by cleft lip and cleft palate but had at least one child born with nonsyndromic cleft. Group B consisted of 80 healthy parents not affected by cleft lip and cleft palate and had healthy children without cleft lip and cleft palate.

Main Outcome Measures:

Main outcome measures were marked dermatoglyphic asymmetry and specific lip print pattern in the study group.

Results:

We found marked asymmetry in various fingerprints and specific type II and type III lip print in the study group when compared with the control group. It was observed that groove count on the lip was significantly more frequent in study group parents.

Conclusion:

Our study determined that there is a significant correlation between increased dermatoglyphic asymmetry and specific type II and type III lip print pattern in parents of children born with cleft. This could act as an important screening marker for the prediction of cleft lip and cleft palate inheritance.
