Alternative approaches to sex determination of DNA samples involve investigation of regions of the amelogenin gene. This is the gene that encodes tooth enamel and is present on both the X and Y chromosomes. A review composed via Medline Internet search of literature and contributions from our experiences as well as experiences from colleagues. The rareness of failures in sex determination provides confidence in current techniques, but amelogenin gene method (singly) of sex determination is not without failures. Amelogenin PCR method/system of sex determination should not, at the moment, completely replace traditional methods of sex identification. Hence, sex identification with amelogenin gene, of subjects for forensic purposes should be conducted as much as possible through a multiple morphological-molecular combined methods to avoid fallibility of amelogenin gene.
