Human facial morphology is diverse between individuals and communities, and is affected by gene polymorphisms. We investigated the effects of Single Nucleotide Polymorphisms (SNPs) of ENPP1 and GHR genes on facial features. 20 volunteers over the age of 18 without birth defects, facial trauma, reconstructive and plastic surgery, facial and dental implant treatment, orthognathic/maxillofacial surgery story and facial paralysis or neurological problems resulting any facial abnormalities were selected for the study. Two SNP genotypes and a total of 40 samples were studied. 15 anatomic regions were identified on the face and 27 physical measurements were made between these 15 regions. ENPP1 (rs7754561) and biometric measurements between the points were found associated significantly. We believe that the data obtained from this study might be one of the study for the development of the powerful identification methods from DNA in forensic sciences. The information obtained from DNA analysis might be used for drawing 2D or 3D robot images. If the genes affecting the facial morphology and the variants of these genes are well understood, it would be possible to reach the person whose DNA could not be identified in databases.
