Abstract: Objective To investigate the clinical manifestations, genetic basis and related literatures of Boucher-Neuh(a)user syndrome(BNS), hoping to help physicians recognize this rare disease. Methods A 25-year-old BNS patient was reported.The clinical manifestations and the laboratory data including fundus examination, blood testing, brain MRI and genetic data were summarized.The related literatures were also reviewed.Results The patient presented with tremors, ataxia, secondary sexual characteristics dysplasia,epilepsy, and then got worse progressively.Brain MRI showed severe cerebellar atrophy.Two mutations of PNPLA6 gene were found: one is the heterozygous mutation c.1811C >T (p.A604V),which has not been reported;another is c.2990C>T(p.S997L),which has been reported as a pathogenic mutation related to BNS.Conclusion PNPLA6-related BNS may be considered for adolescent patients with tremor and ataxia,secondary sexual characteristics dysplasia and epilepsy.
