PSTPIP2 and chronic recurrent multifocal osteomyelitis: A mouse model Pstpip2cmo/cmo (with a missense point-mutation in Pstpip2; ‘cmo’, chronic multifocal osteomyelitis) shows pathological characteristics reminiscent of human CRMO and has been widely used as an animal model for pathophysiological dissection of CRMO and general AIDs (Byrd et al., 1991; Ferguson et al., 2006).
