Researchers say they have verified and sequenced Hitler’s DNA. A new documentary reveals the findings

Researchers analyzed a DNA sample believed to belong to Adolf Hitler; The dictator of Nazi Germany had a genetic marker for a rare disease that could delay puberty, a new documentary has revealed.

The research, which took more than four years to complete, was led by geneticist Turi King, a professor at the University of Bath in the United Kingdom. King III. Richard’s remains. King said he confirmed that a piece of material taken from the couch in the bunker where Hitler shot himself in 1945 was stained with the dictator’s blood by comparing a DNA sample obtained from the blood to a confirmed relative of Hitler.

In addition to suggesting the possibility that Hitler had a congenital disorder that disrupted hormones, Kallmann syndromeThe documentary examined rumors of the dictator’s Jewish ancestry and looked at whether he might have a genetic predisposition to certain mental health conditions. The documentary, called “Hitler’s DNA: The Blueprint of a Dictator,” premieres on Channel 4 in the United Kingdom on Saturday.

However, the fact that the findings shared in the documentary have not been examined by other scientists in the field or published in a scientific journal makes it difficult for experts not involved in the project to evaluate the validity of the claims. King said the analysis had been submitted to a “high-profile” journal and he hoped the study would be published soon.

The tiny piece of frayed fabric began its journey in 1945 in the hands of US Army Colonel Roswell P. Rosengren, who was General Dwight D Eisenhower’s communications officer. According to the documentary, when Rosengren was allowed into Hitler’s bunker by Soviet forces, he had cut a piece of material from a bloody couch. The swatch remained in Rosengren’s family before being offered for sale at auction in 2014 and purchased by Rosengren. Gettysburg History Museum in Pennsylvania.

“We didn’t know what we would find,” King said. “It might have been the most boring genome on the planet, but it was incredible.”

The most striking finding from the team’s analysis was that Hitler had a mutation in a gene called PROK2. Variants in this gene It is a cause of Kallmann syndrome It’s congenital hypogonadotropic hypogonadism, King said. In boys, these conditions can delay puberty and cause the testicles to fail to descend.

“They are basically characterized by low testosterone levels. You either don’t go through puberty or you go through partial puberty… 5% of cases are associated with a problem. micropenis” said King, referring to a small but normally built penis.

Clues in historical records

Nicholas F. Bellantoni, a retired state archaeologist at the Connecticut State Museum of Natural History, said that at the time of his death, Hitler was seen with a gun at the end of the couch, with blood splattered on the couch and the wall behind it. In 2009 he examined parts of the sofa that is now in Russia.

“If it is confirmed that the source of the sofa material used came from the Bunker and the sofa on which Hitler and Hitler sat Eva Braun “If he is dead, then there is a very good chance that the blood came from Hitler,” Bellantoni said via email.

According to Alex Kay, an expert on Nazi Germany and senior lecturer at the Department of War Studies at the University of Potsdam in Germany, the new details revealed by King appear to be consistent with the historical record. Kay also appeared in the documentary.

He stated that a medical document had been found from Hitler’s time in prison after a failed coup known as Munich. beer hall coup In 1923, he claimed that the dictator suffered from right-sided cryptorchidism (a condition in which one testicle does not descend into the scrotum).

“The discovery of Kallmann syndrome is an important finding for me personally as a historian and someone who has studied the Nazis for over 20 years,” Kay said. He added that the information potentially explained Hitler’s lack of personal relationships.

Kay and King said the findings also dispel persistent rumors that Hitler had Jewish ancestry; These speculations stemmed from the fact that Hitler’s grandmother became pregnant while working in a Jewish household, according to the documentary.

Since the Y chromosome data analyzed in the study matched the DNA of Hitler’s male relative, King said it was not possible for Hitler to have Jewish origins. “If that were the case, we wouldn’t be able to find a DNA match with him,” King said. “This DNA match not only confirmed that this was Hitler’s DNA, but also confirmed that the story of man’s Jewish ancestry from his father was not entirely true.”

The value of historical DNA

King said he initially had some reservations about taking part in the documentary, but decided to participate because he felt his expertise would ensure the analysis would be scientifically rigorous. “This is also not just a documentary, but also an academic paper,” he said, adding that he did not have a publication date to offer.

Scientists have previously used DNA to study well-known historical figures. DNA obtained from a lock of Beethoven’s hair revealed: The composer had health problems. Archaeologists also widely use ancient DNA obtained from human remains.

However, according to Pontus Skoglund, senior group leader at the Ancient Genomics Laboratory at the Francis Crick Institute in London, it is not possible to evaluate the claims made in the documentary without information about the quality of the genome, the raw data or how the analyzes were performed.

“If we step back, the scientific merit of such a media campaign, balanced against the possible stigmatization of individuals today with these real diseases, is also questionable,” Skoglund said.

He added that researchers can share findings with the scientific community on a place known as a preprint server, before formal peer review and publication in an established journal.

Skoglund’s colleague Tom Booth, a bioarchaeologist at the Francis Crick Institute, said it is possible to extract historical DNA from a piece of fabric, but there needs to be good justification and a specific set of questions to examine DNA from historical figures.

“There are extensive historical records documenting Hitler’s behavior in public and private,” Booth said via email. “(H)e is probably one of the most intensely studied figures in history, so I think it’s hard to argue that DNA evidence adds much to that.

“Even the diagnosis of Kallmann syndrome may not be as straightforward as the headlines suggest. There can be so much variation in its physical presentation, and while this is a plausible explanation for his undescended testicle, it doesn’t justify the amount of ‘micropenis’ in my news feed.”

‘A tiny little puzzle piece’

The researchers also said they calculated a polygenic risk score, which involves sifting a person’s DNA to measure disease risk. The findings showed that Hitler had an increased genetic predisposition to schizophrenia, attention deficit hyperactivity disorder and autism.

However, Ditte Demontis, a professor of psychiatric genetics at Aarhus University in Denmark who was involved in the research and appeared in the documentary, said that the polygenic risk score is a tool used today for research purposes, it is not diagnostic and does not necessarily mean that Hitler had these conditions.

“We are currently in a situation where polygenic risk scores for psychiatric conditions are used only in a research context,” Demontis emphasized. “We can say things at the group level, but not at the individual level.”

Demontis compared Hitler’s polygenic risk score with that of 30,000 Danes and found that if Hitler were alive today, “his score for schizophrenia, autism and bipolar disorder would actually be higher than 99% of individuals in the Danish population.” He added that it is rare to have a high polygenic risk score for all three conditions.

“It’s not diagnostic, and I also want to emphasize that the score in no way leads to specific types of behavior or actions,” Demontis said.

The king agreed. “We make a huge effort to not stigmatize people with these conditions, because, you know… it’s incredibly rare for people with these conditions to go on to commit violent acts,” he said.

“The other thing was that Hitler did not act alone, he had hundreds and thousands of people helping him,” King said. “Not all of them will have the same genetic makeup as him. His genetics are just a tiny little puzzle piece.”
