South Asians underrepresented in global health databases, hindering AI-driven healthcare
South Asians are significantly underrepresented in global health databases, with less than 1% participation in genome-wide association studies despite facing higher rates of diseases like type 2 diabetes and cardiovascular disease. This data gap limits the accuracy of AI models and polygenic risk scores for South Asian populations, leading to less effective disease prediction and tailored treatments. The issue stems from historical underfunding in low- and middle-income countries, resulting in inadequate infrastructure for genomic research. Scientists are now advocating for greater regional collaboration and investment in building South Asian-specific databases, like India's GenomeIndia Project, to ensure equitable and accurate healthcare.
Key Points
- South Asians are severely underrepresented in global health databases, impacting the accuracy of AI models and risk prediction tools for this population.
- The lack of diverse data leads to less effective disease prediction and tailored treatments for South Asians, who have higher rates of certain diseases.
- Historical underfunding and inadequate research infrastructure in LMICs contribute to this data disparity.
- Regional collaboration and investment in South Asian-specific genomic databases are crucial to address the imbalance and ensure equitable healthcare.
- Projects like India's GenomeIndia aim to capture the genetic diversity of the region and build a reference database.
Exam Facts
- More than 1 in 10 adults globally live with diabetes, with South Asians facing higher risk.
- Between 2005 and 2025, over 86% of participants in human genome-wide association studies were of European ancestry, while South Asians accounted for less than 1%.
- The GenomeIndia Project, launched in 2020, has identified over 40 million genetic variants unique to the Indian population.
- A 2023 study found polygenic risk scores for multiple sclerosis were less accurate when applied to South Asian populations.
