Hypothesis
We aimed to identify protein targets for dyslipidaemia and cardiovascular diseases in South Asians.
Conclusion
The study found potential causal links between plasma proteins and dyslipidaemia in South Asians, highlighting significant differences compared to Europeans.
Supporting Evidence
- 29 genetically proxied proteins were identified as potentially causal to at least one lipid measure.
- 12 proteins showed strong colocalization and generalized MR evidence.
- PCSK9 had a stronger association with LDL-C in Europeans compared to South Asians.
- Observational analysis suggested significant interaction between PCSK9 levels and LDL-C levels in South Asians.
Takeaway
This study looked at proteins in South Asians that might affect heart health, finding some important differences from Europeans.
Methodology
A two-sample Mendelian randomization approach was used to evaluate the effect of plasma proteins on lipid measures.
Limitations
Larger studies in South Asians are needed to validate these findings.
