Sialidosis are autosomal recessive inherited disorders caused by a mutation on the NEU1 gene. In type 1 sialidosis, a "cherry-red spot" can be observed in fundoscopic examinations. In this study, a woman aged 37 years without "cherry-red spot" on ophthalmologic examination is reported to draw attention to a new phenotypic variation. Although an ophthalmologic examination was normal, for patients with consanguineous parents with progressive ataxia, drug-resistant epilepsy and myoclonus must be investigated for progressive myoclonic epilepsy and genetic analysis for sialidosis must be performed. The diagnosis is also crucial for genetic consultancy of the family.
