Molecular analysis of the coronavirus spike protein within the tissues identified a specific, functionally relevant amino acid change (R793M), which was only identified in tissues associated with the central nervous system (ie, brain and spinal cord). RELEVANCE AND NOVEL INFORMATION: This case report describes an early presentation of a cat with primarily neurologic FIP, with molecular characterization of the virus within various tissues. 18 Molecular analysis of the viral spike protein within the tissues identified a specific, functionally relevant amino acid change (R793M), which was only identified in tissues associated with the CNS (ie, brain and spinal cord). This case report describes a young cat with neurologic FIP in which detailed clinical and molecular characterization of the associated FCoV infection was performed. ./cache/cord-324530-tac1unnp.txt ./txt/cord-324530-tac1unnp.txt
