Polygenic Income Index Explains Health Gap

This study shows common genetic variants, aggregated into a polygenic index, are statistically associated with income and with markers that help explain the socio‑economic gradient in health. The index accounts for a small but measurable share of income variance (about 1–5%), implying genetics contributes to but does not determine economic status; family and environmental confounding remain important caveats. — The finding reframes parts of the inequality and public‑health conversation: it demands careful policy discussion about using genetic information in social science, anti‑discrimination safeguards, and how to target social determinants of health without genetic determinism.
