Introduction The association of neuromyelitis optica (NMO) and multiple sclerosis (MS) has been reported, but details of the cases were not described. We report two Venezuelan Caucasian sisters with human leukocyte antigen (HLA) typing. Results Patient 1 fulfilled McDonald, et al. criteria with HLA A*24; B*07,*15; DRB1*01,*16 (DR2 positive). Patient 2 fulfilled the NMO revised criteria of Wingerchuck, et al. with HLA A*02,*24; B*07,*40; DRB1*04,*08, similar to Canadian aboriginal NMO cases and the Yukpa population from Venezuela. Conclusion These cases confirmed the coexistence of NMO and MS in sisters, and further studies are needed to understand the genetic linkage between these diseases. Key Words: Devic's disease, human leukocyte antigen, multiple sclerosis, neuromyelitis optica, relapsing neuromyelitis optica
