Overview
- Geneticist Turi King led a British team that sequenced Hitler’s DNA from a blood‑stained fragment cut from his Berlin bunker sofa in May 1945 for a Channel 4 documentary.
- Sequencing identified a mutation in the PROK2 gene strongly associated with Kallmann syndrome, which affects pubertal development and can result in low testosterone.
- The conclusion is consistent with a 1923 Landsberg prison medical record noting right‑sided cryptorchidism in Hitler.
- Researchers say the genetic profile shows no evidence of a Jewish ancestor, citing concordance with markers from Hitler’s male‑line relatives.
- Polygenic risk scores placed him in high percentiles for autism, schizophrenia and bipolar traits, as experts cautioned that such measures cannot diagnose individuals or account for his actions.
