Microangiopathy and leukoencephalopathy, pontine, autosomal dominant

Autosomal dominant pontine microangiopathy and leukoencephalopathy (PADMAL) is a form of cerebral small vessel disease (CSVD) resulting in the onset of recurrent ischemic strokes in the thirties or forties. Affected individuals develop progressive, but variable, cognitive and motor impairment, consistent with progressive multi-infarct dementia. Brain imaging shows lacunar infarcts, often with a pontine predilection, as well as diffuse leukoencephalopathy affecting various brain regions. Although there are overlapping clinical features, the disorder is genetically and pathologically distinct from CADASIL (125310) (summary by Verdura et al., 2016). [from OMIM]
