Channel 4's new documentary 'Hitler's DNA: Blueprint of a Dictator' claims to have uncovered evidence that Adolf Hitler suffered from Kallmann syndrome, a rare genetic disorder that prevents the onset or completion of puberty. The programme, which analyses DNA from a blood-stained sofa where Hitler died, suggests this condition may have influenced his psychology and actions.
The researchers, led by Professor Turi King, who previously verified the remains of Richard III, and historian Dr Alex Kay, found a deletion in the PROK2 gene consistent with Kallmann syndrome. This aligns with medical records from 1923 showing Hitler had an undescended right testicle, a condition known as cryptorchidism. Up to 10% of Kallmann syndrome patients also have a micropenis, though the documentary does not confirm this in Hitler's case.
The programme also debunks rumours of Jewish ancestry, tracing Hitler's Y-chromosome to a male-line relative. The DNA was matched using a sample collected a decade earlier by a Belgian journalist, though it is unclear if permission was obtained for this use. The documentary suggests Hitler's possible shame about his condition may explain his request for his body to be burned after death, though historians largely attribute this to fear of public display like Mussolini's corpse.
Critics question the ethical justification of the documentary, noting that a previous Channel 4 programme, 'Dead Famous DNA', paid Holocaust denier David Irving for a lock of hair that turned out not to be Hitler's. The new programme's producers tracked down the blood-stained fabric at a museum in Gettysburg, Pennsylvania, and authenticated it through DNA matching.
The documentary argues that understanding Hitler's medical conditions could shed light on his psychology, suggesting he may have transformed personal deficits into ideological fervour. However, it stops short of definitive conclusions, leaving viewers to ponder the implications of the dictator's genetic blueprint.
