Study of Indians finds new pathways to cardiometabolic disease, Pg10

Key Highlights:

• Study identifies new genetic pathways linking lipid metabolites to cardiometabolic disease in Punjabi Sikhs.
• Research confirms the role of LPC O-16:0, an immune system signalling metabolite, in influencing Type 2 Diabetes (T2D) risk.
• An ancestry-specific genetic variant was identified that may protect Asian Indians from heart disease by modulating levels of the metabolite PC 38:4.
• The study highlights the importance of research on diverse ethnic groups to understand molecular pathways of disease development.

Detailed Insights:

• Indians have a genetic predisposition to cardiometabolic disease due to lower lean body mass and higher body fat percentage compared to other populations.
• The study examined 516 lipid metabolites in 3,000 Punjabi Sikhs and was replicated using the U.K. Biobank and other cohorts.
• Circulating lipids and lipid subclasses behave differently in diseased states versus healthy states, impacting T2D, heart disease, and stroke.
• Identifying metabolite markers and genes intersecting with inflammation pathways can aid in formulating targeted prevention strategies for Asian Indians.

Scientific/Technical Concepts Involved:

• Lipidome: The complete set of lipids or fats in the human body.
• Metabolite: A substance produced or used when the body breaks down foods, drugs, or chemicals, or its own tissue.
• Genome-wide association studies (GWAS): An approach used in genetics research to associate specific genetic variations with particular diseases.
