Overview
- An international team reconstructed Hitler’s genome from a blood‑stained sofa swatch taken from his Berlin bunker and led by geneticist Turi King.
- Researchers report a PROK2 gene mutation consistent with Kallmann syndrome, a disorder linked to delayed puberty, low testosterone and undescended testicles.
- A Y‑chromosome match to a known male‑line relative supports the sample’s authenticity and counters the longstanding rumor of Jewish paternal ancestry.
- The genome showed polygenic risk scores in the top one percent for autism, schizophrenia and bipolar disorder, which experts caution are not diagnostic for individuals.
- Historians and clinicians note the limits of genetic inference, citing a 1923 medical record of an undescended testicle and warning against stigmatizing people with similar conditions.
