Journal ArticleDOI
Genetically encoded impairment of neuronal KCC2 cotransporter function in human idiopathic generalized epilepsy
Kristopher T. Kahle,Nancy D. Merner,Perrine Friedel,Liliya Silayeva,Bo Liang,Arjun Khanna,Yuze Shang,Yuze Shang,Pamela Lachance-Touchette,Cynthia V. Bourassa,Annie Levert,Patrick A. Dion,Brian P. Walcott,Dan Spiegelman,Alexandre Dionne-Laporte,Alan Hodgkinson,Philip Awadalla,Hamid Nikbakht,Jacek Majewski,Patrick Cossette,Tarek Z. Deeb,Stephen J. Moss,Igor Medina,Igor Medina,Guy A. Rouleau +24 more
TL;DR: The report of two non‐synonymous functional variants in human KCC2, R952H and R1049C, exhibiting clear statistical association with idiopathic generalized epilepsy (IGE) are described and suggest genetically encoded impairment of K CC2 functional regulation may be a risk factor for the development of human IGE.
Journal ArticleDOI
Novel α1 and γ2 GABAA receptor subunit mutations in families with idiopathic generalized epilepsy
Pamela Lachance-Touchette,Patricia M.G.E. Brown,Caroline Meloche,Peter Kinirons,Line Lapointe,Hélène Lacasse,Anne Lortie,Lionel Carmant,Fiona Bedford,Derek Bowie,Patrick Cossette +10 more
TL;DR: Electrophysiological analysis revealed that K353delins18X and D219N altered GABAA receptor function by reducing the total surface expression of mature protein and/or by curtailing neurotransmitter effectiveness, which would be expected to have a detrimental effect on inhibitory control of neuronal circuits.
Journal ArticleDOI
Recurrent mutations in DNAJC5 cause autosomal dominant Kufs disease
Maxime Cadieux-Dion,Eva Andermann,Pamela Lachance-Touchette,O Ansorge,Caroline Meloche,A Barnabé,Ruben Kuzniecky,F. Andermann,E Faught,S Leonberg,John A. Damiano,Samuel F. Berkovic,Guy A. Rouleau,Patrick Cossette +13 more
TL;DR: DNAJC5, which encodes the cysteine string protein (CSPα), a presynaptic protein implicated in neurodegeneration, causes autosomal dominant Kufs disease, and the leucine residues at positions 115 and 116 are hotspots for mutations and result in a homogeneous phenotype of progressive myoclonus epilepsy with onset around 30 years old.
Journal ArticleDOI
Screening of GABRB3 in French‐Canadian families with idiopathic generalized epilepsy
Pamela Lachance-Touchette,Caroline Martin,Chantal Poulin,Micheline Gravel,Lionel Carmant,Patrick Cossette +5 more
TL;DR: This study screened the open reading frame of GABRB3 in 183 French‐Canadian individuals with IGE, including 88 with CAE, and identified nine single nucleotide polymorphisms (SNPs), five of which are novel.
Journal ArticleDOI
Mutation burden of rare variants in schizophrenia candidate genes
Simon Girard,Patrick A. Dion,Cynthia V. Bourassa,Steve Geoffroy,Pamela Lachance-Touchette,Amina Barhdadi,Mathieu Langlois,Ridha Joober,Marie-Odile Krebs,Marie-Pierre Dubé,Guy A. Rouleau +10 more
TL;DR: The absence of overlap in the genes identified suggests that the number of genes involved in SCZ is likely to be very large; a notion supported by the moderate success of Genome-Wide Association Studies (GWAS).
