An assay using the Federal Bureau of Investigation�s human Combined DNA Identity System (CODIS) primers has been developed for polymerase chain reaction (PCR)-based human identity testing. Recent forensic literature has identified several human populations that carry a deletion mutation in the Y-chromosome copy of the amelogenin locus. This is the standard locus used for gender determination in CODIS. Additionally, the amelogenin male PCR products are very close in size requiring manual annotation of PCR electrophoresis results for this locus.
