髓鞘形成不足-先天性白内障综合征

定义 英文原文（暂无中文）

A rare developmental defect during embryogenesis characterized by congenital or early onset cataracts (usually bilateral), developmental delay, progressive neurologic symptoms (including ataxia, spasticity and sometimes seizures) and mild-to-moderate cognitive impairment. Other major clinical features include truncal hypotonia, dysarthia, cerebellar signs (e.g: truncal titubation and intention tremor) and peripheral neuropathy (e.g: progressive weakness of the muscles in the lower limbs). Hypomyelination associated with periventricular white matter abnormalities is observed. Some patients may have mild lens opacity and cataracts could be absent.
