Polymorphic genetic loci of the deoxyribonucleic acid (DNA) present in formalin-fixed, paraffin-embedded tissues were successfully analyzed by utilizing the polymerase chain reaction. Using this analysis, with three different polymorphic loci [human leucocyte antigen (HLA) DQ alpha, low-density lipoprotein receptor, and parathyroid hormone], fixed tissues representing 14 different individuals were genotyped and could be distinguished from each other. The techniques were further applied to the fixed autopsy tissues of a man in which a question of paternity arose postmortem. Since many individuals have surgical procedures or autopsy, these readily available fixed tissues represent an additional resource for the identification of individuals.
