Recovering DNA from human remains for DNA typing


Human remains may be the only evidence recovered in a case for forensic DNA typing. Several methods have been published to remove and isolate the DNA. Old human remains samples often exhibit evidence of degradation. While DNA extracted from modern bone and teeth may produce a full profile, DNA recovered from old and very old remains may lead to only incomplete or unusable DNA typing profiles. My lab has focused on increasing the quantity of loci that are typed in a DNA profile using DNA from historic period human remains. We have tested several approaches including different extraction methods, whole genome amplification, and high-fidelity DNA polymerases. WGA methods can enrich intact DNA strands in DNA extracts. Obtaining more and longer strand DNA molecules leads to more complete DNA typing profiles. Additionally, we have employed massively parallel sequencing (MPS), a more sensitive tool than the traditional DNA typing method using capillary electrophoresis, for DNA typing and analyzed nuclear and mitochondrial DNA. MPS enables DNA analysts to probe more loci with a DNA sample including loci to enable the prediction of the sex, eye and hair color, skin tone, lineage, and biogeographical ancestry and is being used to solve cold cases.
