Journal ArticleDOI
Short GCG expansions in the PABP2 gene cause oculopharyngeal muscular dystrophy
Bernard Brais,Jean-Pierre Bouchard,Ya-Gang Xie,Daniel Rochefort,Nathalie Chretien,Fernando M.S. Tomé,Ronald G. Lafrenière,Johanna M. Rommens,E. Uyama,O. Nohira,Sergiu C. Blumen,Amos D. Korczyn,Peter Heutink,Jean Mathieu,André Duranceau,François Codère,Michel Fardeau,Guy A. Rouleau +17 more
TL;DR: Pathological expansions of the polyalanine tract may cause mutated PABP2 oligomers to accumulate as filament inclusions in nuclei to cause autosomal recessive OPMD.
Journal ArticleDOI
Gain and loss of function of ALS-related mutations of TARDBP (TDP-43) cause motor deficits in vivo.
Edor Kabashi,Li Lin,Miranda L. Tradewell,Patrick A. Dion,Valérie Bercier,Patrick Bourgouin,Daniel Rochefort,Samar Bel Hadj,Heather D. Durham,Christine Vande Velde,Guy A. Rouleau,Pierre Drapeau +11 more
TL;DR: Together these approaches showed that TARDBP mutations cause motor neuron defects and toxicity, suggesting that both a toxic gain of function as well as a novel loss of function may be involved in the molecular mechanism by which mutant TDP-43 contributes to disease pathogenesis.
Journal ArticleDOI
The K-Cl cotransporter KCC3 is mutant in a severe peripheral neuropathy associated with agenesis of the corpus callosum.
Heidi Carmen Howard,David B. Mount,David B. Mount,Daniel Rochefort,Nellie Byun,Nicolas Dupré,Jianming Lu,Xuemo Fan,Luyan Song,Jean Baptiste Rivière,Claude Prévost,Jürgen Horst,Alessandro Simonati,Beate Lemcke,Richard Welch,Roger England,Frank Q. Zhan,Adriana Mercado,Adriana Mercado,William B. Siesser,Alfred L. George,Michael P. McDonald,Jean-Pierre Bouchard,Jean Mathieu,Eric Delpire,Guy A. Rouleau +25 more
TL;DR: These findings identify mutations in SLC12A6 as the genetic lesion underlying ACCPN and suggest a critical role for SLC 12A6 in the development and maintenance of the nervous system.
Journal ArticleDOI
De Novo Mutations in FOXP1 in Cases with Intellectual Disability, Autism, and Language Impairment
Fadi F. Hamdan,Hussein Daoud,Daniel Rochefort,Amélie Piton,Julie Gauthier,Mathieu Langlois,Gila Foomani,Sylvia Dobrzeniecka,Marie-Odile Krebs,Ridha Joober,Ronald G. Lafrenière,Jean-Claude Lacaille,Laurent Mottron,Pierre Drapeau,Miriam H. Beauchamp,Michael S. Phillips,Eric Fombonne,Guy A. Rouleau,Jacques L. Michaud +18 more
TL;DR: Both FOXP1 and FOXP2 are associated with language impairment, but decrease of the former has a more global impact on brain development than that of the latter.
Journal ArticleDOI

TL;DR: This study confirms the involvement of SYNGAP1 in autism while providing novel insight into the epileptic manifestations associated with its disruption, and suggests that the de novo missense mutations, p.R579X, and possibly all the other truncating mutations in SYngAP1 result in a loss of its function.
