Transfers cholesterol between lipoproteins.
| Genotype | Impact | What it means |
|---|---|---|
| GG (Normal) | Normal | B1/B1 (GG), higher CETP activity associated with comparatively lower HDL cholesterol. A Mediterranean-style diet rich in olive oil and oily fish (omega-3), plus regular physical activity, helps support healthy HDL. |
| GA (Carrier) | Low impact | B1B2 genotype, intermediate CETP activity. Tendency toward favourable HDL cholesterol levels. Mediterranean diet rich in olive oil and moderate alcohol intake (if appropriate) further support HDL. |
| AA (Variant) | Moderate | TaqIB B2 allele (AA), associated with lower CETP activity and higher HDL cholesterol, generally a favourable lipid profile. Support cardiovascular health with omega-3s, extra-virgin olive oil and regular physical activity. |
