Overview
- Scientists reconstructed a genome from a blood‑stained sofa fragment reportedly taken from Hitler’s Berlin bunker in 1945, a relic later held by the Gettysburg Museum of History.
- Researchers say they found a variant in the PROK2 gene consistent with Kallmann syndrome, aligning with a 1923 medical record of an undescended testicle and implying low testosterone with a chance of a micropenis.
- The team reports very high polygenic risk scores for autism, schizophrenia and bipolar disorder, noting such scores are not clinical diagnoses and have limited individual predictive power.
- A Y‑chromosome match to a known male‑line relative is presented as verification that the blood came from Hitler and as evidence against the specific rumor of a Jewish grandfather.
- The findings are being unveiled ahead of Channel 4’s two‑part documentary, with experts stressing that genetics cannot explain behavior and warning against stigmatizing people with similar conditions.
