| Genotype | Impact | What it means |
|---|---|---|
| GG (Normal) | Normal | Normal renal sodium handling - typical salt sensitivity. Keep sodium moderate and a potassium-rich diet. |
| GT (Carrier) | Moderate | Slightly increased salt sensitivity. Moderate sodium (<5 g salt/day) and emphasise potassium-rich foods (vegetables, fruit, legumes). |
| TT (Variant) | High impact | Salt-sensitive hypertension risk. Limit added salt and processed foods, boost potassium and magnesium, and monitor blood pressure. |
