Chorea-acanthocytosis (ChAc) is a severe, neurodegenerative disorder that shares clinical features with Huntington's disease and McLeod syndrome. It is caused by mutations in VPS13A, which encodes a large protein called chorein. Using antichorein antisera, we found expression of chorein in all human cells analyzed. However, chorein expression was absent or(More)
The availability of Erythropoietin (Epo) is essential for the survival of erythroid progenitors. Here we study the effects of Epo removal on primary human erythroblasts grown from peripheral blood CD34(+) cells. The erythroblasts died rapidly from apoptosis, even in the presence of SCF, and within 24 hours of Epo withdrawal 60% of the cells were Annexin V(More)
A 50-year-old man presented with worsening, virtually lifelong, chorea and progressive behavioural disturbance, involving disinhibition and hoarding, over 10 years. Clinical assessment revealed chorea, dysarthria, areflexia, an inappropriately jovial, impulsive manner and neuropsychological evidence of frontosubcortical dysfunction. Investigation results(More)
