Thailand's medical sector has acquired Next-Generation Sequencing (NGS) technology that can diagnose rare genetic diseases in under a week—down from 4–10 years—potentially preventing blindness, disability, and death. High-standard labs and medical centers exist nationwide, but experts argue the real bottleneck is lack of integrated infrastructure connecting patients, diagnostics, and treatment. Prof. Vorasak Shotelersathit (Chulalongkorn University) presented data showing rare diseases affect 3.5–5.9% of the global population (300+ million people)—more than 7× the number of people with HIV—yet policy investment remains limited. The case studies highlight how early NGS screening could have saved a Thai girl's eyesight, while a premature infant received diagnosis in five days. System integration, not technology, is now the priority for a national rare-disease policy.
