Aim: The aim of the study was to study the various pattern types of lip prints in parents of cleft lip and palate (CLP) siblings to detect if any specific pattern can be considered as a genetic marker. Patients and Methods: The study included 100 participants (study group parents with children having CLP, fifty fathers and fifty mothers) and fifty participants (control group parents having children without CLP, 25 fathers and 25 mothers. The lip prints of the participants were obtained using the cellophane method and analyzed using Suzuki and Tsuchihashi classification of lip prints. The data were subjected to Chi-square test. Results: On the basis of the logistic regression, prediction of 27% of abnormal pattern in more than one-quadrant of lip can be considered as genetic marker for cleft lip (palate) deformity. Discussion: In our study, abnormal pattern Type V had been found which was considered as genetic marker for transmission of cleft lip (palate) deformity and a predominant pattern of Type II was found which was same in lines of An Egyptian study. Conclusion: A highly significant correlation was observed in lip patterns in parents with cleft anomalies.
