Overview
- Scientists built a genome profile from a blood‑stained swatch taken from Hitler’s bunker sofa in 1945 and authenticated it by matching his Y chromosome to a known male relative.
- The team reports a high likelihood of Kallmann syndrome, a sexual‑development disorder linked to low testosterone, undescended testicles, and a raised chance of a micropenis, aligning with a 1923 medical record.
- Polygenic risk scores placed Hitler in the top percentile for autism, schizophrenia and bipolar disorder, but experts stressed such scores are probabilistic and not clinical diagnoses.
- The analysis indicates Austrian‑German paternal lineage and counters long‑standing claims of a Jewish grandfather, based on the Y‑chromosome match within his male line.
- The findings, led by geneticist Turi King and featured in Channel 4’s two‑part Hitler’s DNA: Blueprint of a Dictator, also foreground ethical concerns and warnings against genetic determinism.
