    • Hereditary diffuse leukoencephalopathy with spheroids (HDLS) is an autosomal-dominant central nervous system white-matter disease with variable clinical presentations, including personality and behavioral changes, dementia, depression, parkinsonism, seizures and other phenotypes. We combined genome-wide linkage analysis with exome sequencing and identified 14 different mutations affecting the tyrosine kinase domain of the colony stimulating factor 1 receptor (encoded by CSF1R) in 14 families with HDLS. In one kindred, we confirmed the de novo occurrence of the mutation. Follow-up sequencing identified an additional CSF1R mutation in an individual diagnosed with corticobasal syndrome. In vitro, CSF-1 stimulation resulted in rapid autophosphorylation of selected tyrosine residues in the kinase domain of wild-type but not mutant CSF1R, suggesting that HDLS may result from partial loss of CSF1R function. As CSF1R is a crucial mediator of microglial proliferation and differentiation in the brain, our findings suggest an important role for microglial dysfunction in HDLS pathogenesis.

  • Autosomal dominant Parkinson's disease.

  • Ingår i: Parkinsonism & related disorders. - 1873-5126. ; 18 Suppl 1
  • Forskningsöversikt (refereegranskat)abstract
    • Over the past two decades the understanding and classification of Parkinson's disease (PD) has been revolutionized by genetic research. Currently, sixteen PARK loci have been identified with autosomal dominant genes such as SNCA, and LRRK2, and autosomal recessive genes such as PRKN, DJ-1, and PINK1. Among these genes, LRRK2 is the most prevalent. Additionally, susceptibility variants located on some of these genes are widely recognized as risk factors for PD in certain ethnic populations. Alpha synuclein Lewy body (LB) pathology, the hallmark of sporadic PD, is predominantly seen in carriers of SNCA and LRRK2. Recently two new autosomal dominant PD genes have been discovered, eukaryotic translation initiation factor 4-gamma (EIF4G1) and vacuolar protein sorting 35 (VPS35). EIF4G1 is associated with LB pathology; however, only limited data currently exists on pathology of the VPS35. Thus, it remains to be seen if LB pathology can be identified on autopsy examination of carriers of VPS35 gene. The mechanism behind the cause of PD has yet to be elucidated; however, genetic studies on autosomal dominant PD have provided novel insights into the potential etiology of PD. Thus, paving the way for future targeted therapies aimed at disease prevention and cure.
