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 swatch of fabric from the sofa where he died. The programme, airing a decade after the broadcaster's previous failed attempt, reportedly confirms that Hitler had a rare genetic disorder called Kallmann syndrome, which can cause a micropenis and undescended testicles.
The documentary team tracked down the bloodied fabric in a Gettysburg museum and matched it to a male-line relative's DNA sample collected 10 years earlier. Led by Professor Turi King, who verified Richard III's remains, and historian Dr Alex Kay, the researchers found a deletion in the PROK2 gene consistent with Kallmann syndrome. This aligns with 1923 prison medical records noting 'right-side cryptorchidism' (an undescended right testicle).
The programme also debunks rumours of Jewish ancestry, tracing Hitler's paternal lineage. However, ethical concerns arise over using a relative's DNA without clear permission and the justification for probing Hitler's medical history. Critics argue that fears of posthumous exposure, not a hidden condition, likely motivated Hitler's request for his body to be burned.
Despite these issues, the documentary suggests that Hitler's medical conditions may have influenced his psychology, potentially compensating for personal deficits through ideological extremism. The programme aims to contribute to historical understanding, but questions remain about the propriety of such genetic analysis.
