In patients with >1 neural antibody, features associated with each antibody specificity often occurred (e.g., a male patient with ANNA‐2 and KLHL‐11‐IgGs presented with jaw dystonia [most commonly ANNA‐2 associated] and an underlying testicular germ cell tumor [KLHL‐11 associated]), emphasizing the clinical utility of comprehensive neural antibody evaluations in patient management. The gene discussed is KLHL11; the disease is testicular germ cell tumor.
