Hypothesis
We aimed to identify protein targets for dyslipidaemia and cardiovascular diseases in South Asians.
Conclusion
The study identified several proteins linked to lipid levels and cardiovascular disease risk 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 GMR evidence.
- PCSK9 demonstrated a stronger association with LDL-C in Europeans compared to South Asians.
Takeaway
Scientists studied proteins in South Asians to find out which ones might help with heart disease and high cholesterol. They found some proteins that are important for these health issues.
Methodology
The study used a two-sample Mendelian randomization approach to evaluate the effect of 2,800 plasma proteins on lipid traits and cardiovascular disease.
Potential Biases
Unaccounted pleiotropy may still bias the results.
Limitations
The genetic associations for plasma proteins in South Asians were based on a relatively small sample size, and larger studies are needed for validation.
Participant Demographics
Participants were of South Asian ancestry, specifically Central/South Asian.
