[email protected] evidence can be crucial in instances such as identification of victims of mass disaster, missing persons investigations, and sexual assault cases. Submission: 29 July, 2014 The Y chromosome marker amelogenin is currently in widespread use Accepted: 18 August, 2014 for determination of chromosomal sex of an unknown DNA donor and Published: 21 August, 2014 differentiating the relative contributions of male and female DNA in a mixed forensic sample. However, many cases of the failure of the amelogenin marker to correctly determine the sex of DNA donors Forensic Markers For Sex Identification have been reported, causing the usefulness of the amelogenin marker in forensics to be questioned. In this paper we review use of Amelogenin amelogenin as a marker for sex identification in forensics and describe four additional Y chromosome markers, sex-determining region Y (SRY), The application of amelogenin marker in forensic caseworks: Y-encoded testis-specific protein (TSPY), locus DXYS156, and steroid The amelogenin (AMEL) locus encodes a matrix protein forming sulfatase (STS).
