Altered immune pathways in patients of temporal lobe epilepsy with and without hippocampal sclerosis.

Over the past decades, the immune responses have been suspected of participating in the mechanisms for epilepsy. To assess the immune related pathway in temporal lobe epilepsy (TLE), we explored the altered immune pathways in TLE patients with and without hippocampal sclerosis (HS). We analyzed RNA-seq data from 3 TLE-HS and 3 TLE-nonHS patients, including identification of differentially expressed RNA, function pathway enrichment, the protein-protein interaction network and construction of ceRNA regulatory network.

Mutation screening of the PRRT2 gene for benign epilepsy with centrotemporal spikes in Chinese mainland population.

Proline-rich transmembrane protein 2 gene (PRRT2) mutations are reported to cause common paroxysmal neurological disorders and show a remarkable pleiotropy. Benign epilepsy with centrotemporal spikes (BECTS) is considered to be the most common epilepsy syndrome in childhood. It is placed among the idiopathic localization related epilepsies.

The single nucleotide polymorphism Rs12817488 is associated with Parkinson's disease in the Chinese population.

A recent meta-analysis of datasets from five of the published Parkinson's disease (PD) genome-wide association studies implicated the single nucleotide polymorphism (SNP) rs12817488 in coiled-coil domain containing 62 (CCDC62)/huntingtin interacting protein 1 related (HIP1R) as a risk factor for PD. We conducted a case-control study to evaluate the possible association between rs12817488 and PD in Chinese people. All patients (515 PD patients and 518 age and sex-matched controls) were successfully genotyped using polymerase chain reaction restriction fragment length polymorphism analysis.

Increase of the plasma α-synuclein levels in patients with multiple system atrophy.

Multiple system atrophy, a sporadic neurodegenerative disease, is characterized by the presence of high numbers of glial cytoplasmic inclusions mainly formed by α-synuclein protein, which is encoded by the SNCA gene. To date, however, few studies have investigated the plasma α-synuclein levels in patients with multiple system atrophy. We studied plasma α-synuclein concentrations by using an enzyme-linked immunosorbent assay in 74 patients with multiple system atrophy and 90 healthy controls.

Using next-generation sequencing as a genetic diagnostic tool in rare autosomal recessive neurologic Mendelian disorders.

Next-generation sequencing was used to investigate 9 rare Chinese pedigrees with rare autosomal recessive neurologic Mendelian disorders. Five probands with ataxia-telangectasia and 1 proband with chorea-acanthocytosis were analyzed by targeted gene sequencing. Whole-exome sequencing was used to investigate 3 affected individuals with Joubert syndrome, nemaline myopathy, or spastic ataxia Charlevoix-Saguenay type.
