Quiz of God [1] [2] [3] (Korean : 신의 퀴즈; Hanja : 神의 퀴즈; RR : Shineui Kwijeu;lit. God's Quiz) is a South Korean television series broadcast on cable channel OCN. [4] It was the first medical/forensic crime investigation drama to air in Korea. The series follows genius but eccentric neurosurgeon and forensic doctor Han Jin-woo (played by Ryu Deok-hwan) and his team as they solve suspicious deaths and unravel mysteries involving rare diseases. [5]


The title refers to a local saying that rare diseases are like quizzes God gives to humans so as not to become too arrogant. The first season dealt mostly with inherited rare diseases including porphyria, phenylketonuria, muscular dystrophy, Guillain–Barré syndrome, reflex anoxic seizures and Savant syndrome. Fabry disease, Kleine–Levin syndrome and congenital insensitivity to pain with anhidrosis were featured in the second season. [6]
