Hypothesis

Do the APOA5 gene variants -1131T>C and S19W show similar associations with lipid parameters in the Indian population as seen in Caucasians?

Conclusion

The study confirms that APOA5 variants are associated with triglyceride levels in both Asian Indians and Caucasians, with the -1131C allele being more prevalent in Pune Indians.

Supporting Evidence

  • The -1131C allele was found in 20% of Pune Indians compared to 4% in UK whites.
  • The presence of -1131C allele was associated with a 19% increase in triglyceride concentrations.
  • The study is the first to investigate APOA5 variants in Asian Indians residing in India.

Takeaway

This study looked at how certain gene changes affect fat levels in people from India and found that one gene change is more common in them than in people from Europe.

Methodology

Genotyping of 557 Indian adults and 237 UK white adults for APOA5 variants and analysis of their association with lipid parameters using general linear analysis.

Limitations

The study may not be generalizable to all South Asian populations as it focuses on a specific cohort from Pune.

Participant Demographics

557 Pune Indian adults and 237 UK white adults, with a median age of 36 years for Pune Indians.

Statistical Information

P-Value

p = 0.00001 for -1131C allele prevalence

Confidence Interval

95% CI, 0.12–0.39 for triglyceride increase associated with -1131C allele

Statistical Significance

p<0.00001
