Overview
- Sequencing of DNA from a blood‑stained sofa fragment points to a PROK2 gene deletion consistent with Kallmann syndrome, which affects sexual development.
- The team reports very high polygenic risk scores, in the top one percent, for predisposition to autism, schizophrenia and bipolar disorder, though these scores are not diagnostic.
- Findings undermine long‑running claims of Jewish forebears, indicating Austrian‑German lineage through a confirmed male‑line match.
- Researchers estimate about a one‑in‑ten chance of a micropenis, aligning with a 1923 record of an undescended testicle and contemporaneous accounts of genital abnormalities.
- The results, led by geneticist Turi King, are presented with ethical cautions that genetics cannot explain or excuse Hitler’s crimes, and will be detailed in Channel 4’s two‑part documentary airing in the UK this weekend.
