Introduction: Wilson disease (WD) is an autosomal-recessive disorder of copper metabolism, which exhibits various symptoms due to the combination of environmental and genetic factors. Here, we report a WD patient who displayed distinctive symptom of nocturnal enuresis. Patient concerns: The patient was a 31-year old woman, who recently developed nocturnal enuresis, combined with hand tremors, trouble speaking, and panic disorder at night. Diagnosis: The patient had been diagnosed with WD by Kayser-Fleischer rings, abnormal copper metabolism, neuropsychiatric symptoms, and magnetic resonance imaging when she was 17. The diagnosis was further confirmed by genetic analysis, which revealed a compound heterozygous mutations in ATP7B gene (c.2195T>C and c.3044T>C). The patient exhibited nocturnal enuresis, but the ambulatory electroencephalogram, routine urinalysis, residual urine detection, color doppler ultrasound of kidney, ureter, and bladder all displayed no abnormality. Interventions: The patient was treated with sodium dimercaptosulphonate, supplemented with Glutathione and Encephalin-inosine. Outcomes: The urinary copper excretion level decreased gradually, and the nocturnal enuresis was alleviated along with the neuropsychiatric symptoms by copper chelation therapy. Conclusion: In this study, we proved that variants c.2195T>C and c.3044T>C is involved in pathogenesis of WD, and revealed that nocturnal enuresis may be a symptom of WD.
