    • We have found strong evidence of a genetic association of two single nucleotide polymorphisms on chromosome 9 with sporadic ALS, in line with findings from previous independent GWAS of ALS and linkage studies of ALS-frontotemporal dementia. Our findings together with these earlier findings suggest that genetic variation at this locus on chromosome 9 causes sporadic ALS and familial ALS-frontotemporal dementia. Resequencing studies and then functional analysis should be done to identify the defective gene.

  • Polymorphisms in the GluR2 gene are not associated with amyotrophic lateral sclerosis
  • 2012
  • Ingår i: Neurobiology of Aging. - : Elsevier BV. - 0197-4580 .- 1558-1497. ; 33:2, s. 418-420

    • Excitotoxicity is thought to play a pathogenic role in amyotrophic lateral sclerosis (ALS). Excitotoxic motor neuron death is mediated through the Ca(2+)-permeable alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA)-type of glutamate receptors and Ca(2+) permeability is determined by the GluR2 subunit. We investigated whether polymorphisms or mutations in the GluR2 gene (GRIA2) predispose patients to ALS. Upon sequencing 24 patients and 24 controls no nonsynonymous coding variants were observed but 24 polymorphisms were identified, 9 of which were novel. In a screening set of 310 Belgian ALS cases and 794 healthy controls and a replication set of 3157 cases and 5397 controls from 6 additional populations no association with susceptibility, age at onset, or disease duration was observed. We conclude that polymorphisms in the GluR2 gene (GRIA2) are not a major contributory factor in the pathogenesis of ALS.

  • Familial Lund frontotemporal dementia caused by C9ORF72 hexanucleotide expansion.
  • 2012
  • Ingår i: Neurobiology of Aging. - : Elsevier BV. - 1558-1497 .- 0197-4580.
  • Tidskriftsartikel (refereegranskat)abstract
    • Frontotemporal dementia (FTD) as an important clinical entity was rediscovered in Lund and Manchester in the early 1990s. Here we show that the large Lund pedigree with behavioral variant of frontotemporal dementia previously described with this disorder has an expansion in the recently described C9ORF72 locus on chromosome 9.
