Got her mummy´s eyes: Eye color investigation using IrisPlex – preliminary study

Abstract

SNP phenotypic markers are being studied by several groups worldwide. As a result, phenotypic loci such as the ones responsible for human eye, hair and skin color are starting to get known. These may provide information for identification of unknown sample donors in criminal casework when there are no suspects. This kind of information may be even more relevant when the sample donor possesses phenotypic characteristics which distinguish him from the population in which he is inserted. Nevertheless, this approach may be used in similar scientific areas. In this work, a DNA sample from a mummified corpse with historical and scientific interest was studied in order to discover more information about who this corps belonged to. One of the tools used in this investigation was IrisPlex, designed for eye color prediction. This study presents one example on how this methodologies may be useful, not only in forensic investigation but also in areas such as physical anthropology.
