Combined effect between two functional polymorphisms of SLC6A12 gene is associated with temporal lobe epilepsy.

Temporal lobe epilepsy (TLE) is the most common epilepsy subtype with complex genetic structure. A recent study in four populations (Ireland, UK, Australia and Finland) reported an allelic association between betaine/GABA transporter-1(BGT-1 or SLC6A12) and mesial temporal lobe epilepsy with hippocampal sclerosis. To demonstrate the association between SLC6A12 gene polymorphisms and TLE, TaqMan method was used to genotype five single-nucleotide polymorphisms of SLC6A12 gene in 358 TLE patients and 596 nonepileptic control subjects of Chinese Han origin.

Role of BDNF Val66Met functional polymorphism in temporal lobe epilepsy.

Various studies suggested that brain-derived neurotrophic factor (BDNF) gene polymorphisms contributed to the development of many neurological disorders. However, whether BDNF Val66Met polymorphism is associated with epilepsy remains controversial. In our study, we tried to investigate the effects of this functional polymorphism on the occurrence of temporal lobe epilepsy (TLE) and its clinical phenotypes.

PRRT2 Mutant Leads to Dysfunction of Glutamate Signaling.

Paroxysmal kinesigenic choreoathetosis (PKC) is an inherited disease of the nervous system. We previously identified PRRT2 as the causative gene of PKC. However, as little is known about the function of PRRT2, elucidating its function will benefit not only PKC studies, but also many other related disorders.

Association of polymorphisms in mitofusin-2 gene with type 2 diabetes in Han Chinese.

MFN2 and ESRRA are candidate genes involved in the pathogenesis of T2D. Five tag-SNPs in MFN2 gene and three in ESRRA gene were selected and genotyped with TaqMan or PCR-RFLP method in stage 1 populations (555 patients with T2D and 649 control subjects) and stage 2 populations (546 patients with T2D versus 419 control subjects) in Han Chinese. And combining our published data, we estimated the interactions between genetic variants in the MFN2, ESRRA, and PGC-1α genes on the T2D risk using MDR.

Targeted genomic sequencing identifies PRRT2 mutations as a cause of paroxysmal kinesigenic choreoathetosis.

Background: Paroxysmal kinesigenic choreoathetosis (PKC) is characterised by recurrent and brief attacks of involuntary movement, inherited as an autosomal dominant trait with incomplete penetrance. A PKC locus has been previously mapped to the pericentromeric region of chromosome 16 (16p11.2-q12.
