A new Channel 4 documentary, Hitler's DNA: Blueprint of a Dictator, claims to have sequenced the genome of Adolf Hitler using a blood-stained fabric from the sofa where he died. The programme aims to settle long-standing rumours about his ancestry and health, including whether he had Jewish roots or a missing testicle.
Researchers matched Y-chromosome DNA from the blood sample to a male-line relative of Hitler, confirming its authenticity. They found no evidence of Jewish ancestry, debunking a persistent myth. However, they discovered a deletion in the PROK2 gene, linked to Kallmann syndrome, a rare disorder that prevents full puberty. This aligns with 1923 medical records showing Hitler had an undescended right testicle.
Kallmann syndrome can cause low testosterone and, in some cases, a micropenis. The documentary suggests these conditions may have influenced Hitler's psychology, potentially driving his ideological fervour as compensation for personal deficits. Critics question the ethical justification for the study, noting relatives' reluctance and the programme's payment to Holocaust denier David Irving in a previous attempt.
Despite ethical concerns, the findings contribute to historical debate, offering biological insights into one of history's most infamous figures. The documentary airs on Channel 4, sparking discussion on the limits of genetic research into evil.
