Perfil das identificações humanas realizadas no Núcleo de Perícia em DNA Forense do estado do Ceará (NUPDF-CE) - PEFOCE

Abstract

The Human identification by examining the desoxirribonucleic acid (DNA) is held by the study of polymorphic regions of the DNA, transferred from the parents to their children by mechanism of genetic inheritance. The more used markers in forensic routine are microsatellites regions or STRs (Short Tandem Repeats), STRs autosomal and Y chromosome (Y-STRs), and hypervariable regions of mitochondrial DNA (mtDNA). These last being implemented with the aim to complement the data obtained with other markers. The survey of all cases of human identification were analyzed at the Núcleo de Perícia em DNA Forense do Estado do Ceará (NUPDF-CE), in the State of Ceará, from January 2011 to October 2013, this study aimed to evaluate the profile cases. From the data obtained, it was verified that there was an increase in the number of cases in recent years. About half of the cases analyzed belongs to the metropolitan area. Most of the cases analyzed were related to males, most of the identification was made from bones; from this type of identification, the femur, the ribs and dental remains were the most sent samples. The cardiac muscle is the main type of sample used in the identification of fetuses and charred bodies, blood and swab blood samples are the most sent samples related to preserved bodies. The techniques and methodologies used have a great discriminatory power, it was necessary one or two samples references for the conclusion of cases; most relatives referred to genetic profile comparison were the presumed cadavers’ mothers.
