Journal Article

Equal parental origin of chromosome 22 losses in human sporadic meningioma: no evidence for genomic imprinting.

Bertrand Fontaine, +6 more
- 01 Nov 1990 - 
TL;DR: In contrast to the embryonal tumors, the meningioma locus on chromosome 22 is inactivated by random mutation in sporadic adultMeningiomas, and the possible role of genomic imprinting in adult tumors of the nervous system is explored.
Journal ArticleDOI

A polymorphism in the glutamate metabotropic receptor 7 is associated with cognitive deficits in the early phases of psychosis.

Boris Chaumette, +10 more
- 02 Jul 2020 - 
TL;DR: A polymorphism located in GRM7, rs1396409, was significantly associated with performance IQ in the discovery cohort of FEP and was replicated in the UHR cohort, highlighting the possible impact of glutamatergic genes in cognitive deficits in the early phases of psychosis.
Journal ArticleDOI

K-Cl cotransport in red blood cells from patients with KCC3 isoform mutants.

P K Lauf, +4 more
- 19 Dec 2006 - 
TL;DR: In HMSN-ACC patients with KCC3 mutants, RBC KCC activity, although indistinguishable from that of the control group, responded differently to biochemical stressors, such as thiol alkylation or Mg removal, thereby indirectly indicating an important contribution of K CC3 to overall KCC function and regulation.
Journal ArticleDOI

Early influence of the rs4675690 on the neural substrates of sadness

Émilie Fortier, +9 more
- 01 Dec 2011 - 
TL;DR: The different pattern of regional brain activation found here during transient sadness - in children carrying the T allele, compared to those carrying the C allele - might increase later in life susceptibility to emotional dysregulation and depressive symptoms.
Journal ArticleDOI

A potential role for zinc in restless legs syndrome.

Pan Chen, +16 more
- 09 Apr 2021 - 
TL;DR: Serum and brain levels of zinc are elevated in RLS for the first time, and the BTBD9 genetic risk factor is confirmed in a new population, although the zinc changes were not significantly associated with risk genotypes.
