Abstract
To identify novel causes of familial neurodegenerative diseases, we extended our previous studies of TAR DNAβbinding protein 43 (TDPβ43) proteinopathies to investigate TDPβ43 as a candidate gene in familial cases of motor neuron disease. Sequencing of the TDPβ43 gene led to the identification of a novel missense mutation, Alaβ315βThr, which segregates with all affected members of an autosomal dominant motor neuron disease family. The mutation was not found in 1,505 healthy control subjects. The discovery of a missense mutation in TDPβ43 in a family with dominantly inherited motor neuron disease provides evidence of a direct link between altered TDPβ43 function and neurodegeneration.

The frequency of a recently described point mutation of the ciliary neurotrophic factor (CNTF) gene was investigated in a population of 154 German patients with motor neuron disease (MND). Twenty-two percent of the patients were heterozygous, 2% homozygous for the CNTF mutation. Since the gene defec
