Family donors expand HIV cures

A sibling donor unexpectedly carrying a protective CCR5‑Δ32 mutation enabled a stem‑cell transplant that appears to have cured an HIV patient — the first documented family‑donor cure. This suggests family screening could occasionally identify rare protective genotypes and affect donor selection strategies for curative transplants. — It implies concrete changes to donor screening, ethical debates over genetic testing of relatives, and potential pressure to use gene editing or donor selection in cure strategies.
