TCF7L2 - what this gene does

TCF7L2 is a transcription factor that influences pathways related to rare disease, mental health, cardiovascular, and metabolic traits. rs10885418 rs12251238 rs10128255 rs12265291 rs10885414

Key takeaways

  • This gene is linked to rare disease and mental health conditions.
  • Variants such as rs10885418 and rs12251238 are associated with these traits.
  • The evidence comes from published GWAS studies.

Notable variants The highest-magnitude variants include rs10885418, rs12251238, rs10128255, rs12265291, and rs10885414. Each has a magnitude of 2.20 and appears in published pages rs####.

Trait associations These variants are associated with rare disease and mental health traits. Replication across multiple studies strengthens the signal.

Evidence quality The evidence is based on GWAS findings from large sample sizes, but most results are population-level signals not individual predictions. The effect sizes are moderate and some findings are single-cohort.

What this is NOT These variants are statistical associations in populations, not deterministic health outcomes for any person. We do not prescribe or diagnose.
