Polycystic Lipomembranous Osteodysplasia With Sclerosing Leukoencephalopathy 2; Plosl2


Polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy-2 (PLOSL2), or Nasu-Hakola disease, is a recessively inherited presenile frontal dementia with leukoencephalopathy and basal ganglia calcification. In most cases the disorder first manifests in early adulthood as pain and swelling in ankles and feet, followed by bone fractures. Neurologic symptoms manifest in the fourth decade of life as a frontal lobe syndrome with loss of judgment, euphoria, and disinhibition. Progressive decline in other cognitive domains begins to develop at about the same time. The disorder culminates in a profound dementia and death by age 50 years (summary by Klunemann et al., 2005).For a discussion of genetic heterogeneity of polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy, see {221770}.
