Anti-infective medicines are crucial for treating infections, but improper dosing can cause toxicity, resistance and treatment failure. Pharmacogenomics can address genetic variations affecting drug efficacy and safety. Despite the high burden of diseases like TB and HIV in Sri Lanka and South Asia, pharmacogenomic data for these populations are limited. This study aims to fill this gap by investigating pharmacogenomic variants in a South Asian population from Sri Lankan. Pharmacogenomic data on anti-infective medicines were obtained from the PharmGKB database, selecting variants with evidence levels 1 A, 1B, 2 A, and 2B. Sri Lankan genetic data were sourced from an anonymized database of 670 Sri Lankans maintained by the Centre for Genetics and Genomics, Faculty of Medicine, University of Colombo. MAFs were compared between Sri Lankan sub-populations and global data from gnomAD, with statistical significance set at p
