Case report: A frameshift mutation in CLCN2-related leukoencephalopathy and retinopathy.

ABSTRACT: Background: Leukoencephalopathy and visual impairment have been linked to loss-of-function mutations in the CLCN2 gene (MIM #600570). However, the ocular features caused by the CLCN2 mutations remain poorly understood and seldom reported. This study aims to present a novel mutation and characterize the ocular phenotype in a Chinese female diagnosed with CLCN2-related leukoencephalopathy (CC2L), also known as leukoencephalopathy with ataxia (LKPAT; MIM #615651). Case presentation: A 20-year-old Chinese female presented with bilateral blurred vision persisting for 2 years, which had worsened over the past 6 months. Ophthalmologic examination revealed bilateral post-capsular cataracts, macular retinal atrophy, and peripheral retinal pigmentation. Swept-sourc
