In 1998, Mitochondrial DNA (mtDNA) was obtained from the hairs of
Marie-Antoinette, two of her sisters, and two living maternal relatives. Those
results did not match the mtDNA of Carl Wilhelm Naundorff
who claimed he was Louis XVII (son of Marie- Antoinette). A later test on what
was believed to be the remains Marie-Antoinette's son matched her sequence.

Amplification of mtDNA D-loop fragments with a length of 200 bp or more from ancient and even from fairly recent biological samples, can lead to erroneous results. This was clearly illustrated in our investigation of the putative heart of Louis XVII. By selecting different sets of primers which amplified shorter fragments of mtDNA (length 109 bp-201 bp), authentic polymorphisms could be visualised which remained undetected with the more classical primers for fragment sizes > 210 bp. Here we have extended those findings to other biological materials. A competitive PCR assay for quantitation of the amount of mtDNA for different fragment lengths, using a 10 bp deletion construct, was applied to ancient material and on a set of hairs of various ages of sampling (1966 up to the present). The results showed that DNA degradation started a few years after sampling. In the DNA extracts of the older hair shafts (1983-1995), the proportion of the number of short fragments to the number of long fragments is on average 4 in contrast to the most recent hair shafts. The numbers of amplifiable mtDNA copies for the hairs from 1975 and older were too small to show a clear difference. Use of long PCR fragments in such cases can yield misleading results. Use of short PCR fragments for the analysis of mtDNA from shed hair, in combination with a competitive PCR assay to determine the state of degradation, should improve the reliability of forensic mtDNA analysis considerably.

The unraveling of the mystery of
Mitochondrial DNA analysis of the putative heart of Louis XVII, son of Louis XVI and Marie-Antoinette
Introduction
This conclusion was based in the first instance on a comparative mitochondrial DNA (mtDNA) analysis of Naundorff's bone and DNA samples of two living maternal relatives of Louis XVII and was proved further by DNA analysis of hair samples of maternal relatives, i.e. two aunts of Louis XVII and his mother.
The crucial question of the mystery remained, Was
it really Louis XVII who died in the
DNA, a minuscule part of every cell in the body, is responsible for all hereditary properties. It has already been proven that the identification of human remains by DNA analysis is an effective instrument in judicial and historical investigations. Indeed DNA analysis led to the successful identification of the remains of the Romanov family and of Josef Mengele. The present investigation focused on what is known as mitochondrial DNA, and not on the classic nuclear DNA that is passed on to the next generation via sperm and egg. The far smaller mtDNA is found in the mitochondria, the energy factories of the cell, and is only passed down through the maternal line by the egg. Furthermore, there are thousands of copies in one cell, which favors survival in old remains such as the heart being studied here. The sequential order of a robust polymorphic section of mtDNA, i.e. the D-loop (displacement loop) region, divided into two hypervariable regions (HVR 1 and FIVR 2), is most suitable for identification studies and has already been analyzed in samples up to 12,000 years old and even on Neanderthal skeletons.
The DNA analysis in the Center for Human Genetics Leuven(
In this investigation, extreme care was taken to prevent contamination in order to obtain accurate results. The heart piece (- 500 mg) was divided into five segments: one segment contained a piece of the aorta, the other four segments were heart muscle. The DNA in the five different segments of the heart was independently extracted by a silica-based method. Both short (between 1 09 and 201 nucleotides) and long (between 214 to 293 nucleotides) fragments of the mtDNA D-loop were amplified by the polymerase chain reaction (PCR) and analyzed by direct sequence analysis on the automated ALF DNA sequencer (Figure 1 shows an example of a piece of the mtDNA sequence).
DNA was obtained in all five heart segments. Quantitation of the number of mtDNA copies surprisingly revealed that the heart contained relatively high amounts of DNA fragments. The number of mtDNA copies of a length of 131 nucleotides in the DNA extracts of the heart muscle varied from 1260 to 3750 copies/pl DNA extract and the number of copies of the longer 258 nucleotide fragments from 3 to 17. On the other hand, the number of copies in the aorta extract revealed for the short fragments only 12 copies/pl DNA extract and 3.5 for the long fragments. The fact that in general much more DNA was obtained for the short pieces, compared to long pieces, indicates that the DNA is very degraded but also that authentic DNA was obtained. Sequence analysis of the long PCR fragments in the five different DNA extracts of the heart piece did not always give straightforward results. Since the heart DNA was degraded into small fragments this is not surprising. On the other hand reproducible sequencing results were obtained for the short PCR fragments. For three DNA extracts of the heart muscle, identical mtDNA D-loop sequences were obtained which differ in five nucleotide positions from the Anderson international reference sequence, namely nucleotide 16519, 152, 194, 263 and 315.1 (Table 1). In one DNA extract of the heart muscle, the same D-loop sequence was also observed but with very minor contamination. The D-loop sequence of the aorta segment revealed also a double sequence at position 152, position 194 could not be analyzed. The last two DNA extracts contained however less DNA than the others (especially the aorta extract). Based on these resuits, one can consider that the mtDNA D-loop sequence with C at position 16519, C at 152, T at 194, G at 263 and C at 315.1 as the consensus heart D-loop sequence and therefore as the authentic sequence (Table 1).
To prove that the heart of the young boy who died in 1795 is from Louis XVII, one needs to compare the heart D-loop sequence with those of maternal relatives of Louis XVII. The mtDNA D-loop sequences of maternal relatives, i.e. two aunts of Louis XVII (Johanna Gabriela and Mada-Josepha), his mother, Marie-Antoinette, and two living maternal relatives (Queen Anna of Romania and her brother André) (Figure 2), were obtained in the Naundorff study. The obtained consensus heart mtDNA D-loop is identical to the sequence of the living maternal relatives of Louis XVII (Table 2). For the other maternal relatives of Louis XVII there is also a match when HVR1 is considered (for HVR2 no result was obtained in the hair samples of Johanna-Gabriela, Maria-Josepha and Marie Antoinette) (Table 2). The match observed between the mtDNA D-loop sequence of the heart and of maternal relatives of Louis XVII, provides very strong evidence that this heart belongs to a child that is maternally related to Marie-Antoinette.
The DNA analyses in the laboratory of the Instituts
of Legal Medicine, Münster (
To avoid contamination extreme care was taken during all steps of the
analysis. The piece of heart tissue was divided into three segments and the
piece of the aorta into two segments. DNA was extracted from each piece of
tissue by two different researchers using two different methods: the
phenol-chloroform method and a silica-based method. Both regions of the mtDNA
D-loop (HVR1 and HVR2) were amplified by the polymerase chain reaction using
two sets of primer pairs for the long and 5 primer sets for the short fragments
respectively. MTDNA could be obtained in two DNA extracts from the heart and in
one of the aorta with both extraction methods. DNA sequencing was carried out
on an ABI Prism 310 automated sequencer and BigDye
Terminator sequencing reagents (ABI-Perkin Elmer,
The sequencing results of the heart and the aorta for the long mtDNA fragments showed an overlap of signals at three sites in the long fragments. This overlap of signals did not occur in the short mtDNA fragments. This indicates that the DNA from the tissue was mildly contaminated by DNA from an investigator.
The sequencing results obtained for HVR1 were identical to the
Since the DNA was highly degraded and existed mostly in small fragments in the samples the results of the short fragments can be considered as the consensus heart sequence in the second hypervariable region (Table 1).
