ABSTRACT
Amelogenin test is often use as a forensic analyses for sex typing. Objective: Based in the amelogenin gene test, to demonstrate the efficacy of a non commercial molecular system for sex identification. Material and methods. A blind transversal, observational and comparative study. DNA was obtained from 457 blood donors wish to participate providing five milliliters of peripheral blood; these samples where amplified by Polymerase Chain Reaction of a region of the amelogenin gene, located in both sexual chromosomes («AMELX» for gene of X chromosome and «AMELY» for gene of Y chromosome). Results: 239 women and 218 men were screened; comparing our results with the participant’s sex and names. Using Epilnfo V6 statistical program, we obtained a 100% of concordance, and 100% of sensibility, specificity and positive and negative predictive values, as well as kappa coefficient of 1 (p › 0.05). Conclusions: We conclude this test is highly reliable to this Mexican population for sex typing.REFERENCES
