Overview
- Researchers led by geneticist Turi King analyzed blood on a fabric fragment said to be cut from Hitler’s bunker sofa, with samples taken in 2019 from a piece now held by the Gettysburg Museum of History.
- Channel 4 says a rare Y‑chromosome marker matched to living relatives makes the identification of the blood as Hitler’s very likely.
- The team reports genetic signals consistent with Kallmann syndrome, aligning with records of testosterone treatment by Theodor Morell and an earlier note of an undescended testicle.
- The analysis also flags elevated genetic predispositions for conditions such as autism, bipolar disorder and schizophrenia, though the researchers and outside experts stress DNA cannot diagnose these disorders or explain behavior.
- Historians and geneticists urge caution due to questions about provenance and contamination of old samples and emphasize that any medical findings do not alter responsibility for Nazi crimes.
