Bi-allelic variants in RNF170 are associated with hereditary spastic paraplegia.

Alterations of Ca homeostasis have been implicated in a wide range of neurodegenerative diseases. Ca efflux from the endoplasmic reticulum into the cytoplasm is controlled by binding of inositol 1,4,5-trisphosphate to its receptor. Activated inositol 1,4,5-trisphosphate receptors are then rapidly degraded by the endoplasmic reticulum-associated degradation pathway.

Support for "Disease-Only" Genotypes and Excess of Homozygosity at the CYTH4 Primate-Specific GTTT-Repeat in Schizophrenia.

Objective: The role of short tandem repeats (STRs) in the control of gene expression among species is being increasingly understood following the identification of several instances in which certain STRs occur identically, or expand differentially, in primates versus nonprimates. These STRs may regulate genes that participate in characteristics that are associated with the divergence of primates from sibling orders (e.g.

A Clinical and Molecular Genetic Study of 50 Families with Autosomal Recessive Parkinsonism Revealed Known and Novel Gene Mutations.

In this study, the role of known Parkinson's disease (PD) genes was examined in families with autosomal recessive (AR) parkinsonism to assist with the differential diagnosis of PD. Some families without mutations in known genes were also subject to whole genome sequencing with the objective to identify novel parkinsonism-related genes. Families were selected from 4000 clinical files of patients with PD or parkinsonism.

Association of β-Secretase Functional Polymorphism with Risk of Schizophrenia.

Aim: The NRG1-ERBB4 neurotransmitter signaling pathway plays a key role in the pathogenesis of schizophrenia (SZ). The intronic single-nucleotide polymorphism rs707284 in ERBB4 links to PI3K-AKT suppression in SZ. Another protein indirectly affecting NRG1-ERBB4 signaling is β-secretase, which is encoded by the BACE1 gene, and activates NRG1 by proteolytic cleavage.

c.376G>A mutation in WFS1 gene causes Wolfram syndrome without deafness.

Wolfram syndrome is one of the rare autosomal recessive, progressive, neurodegenerative disorders, characterized by diabetes mellitus and optic atrophy. Several other features are observed in patients including deafness, ataxia, and peripheral neuropathy. A gene called WFS1 is identified on chromosome 4p, responsible for Wolfram syndrome.

The analysis of association between SNCA, HUSEYO and CSMD1 gene variants and Parkinson's disease in Iranian population.

Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder. Both genetic and environmental factors are involved in the etiology of the disease. Many studies have revealed the susceptibility genes and variations for PD which need further confirmation.

A genetic variant in CAMKK2 gene is possibly associated with increased risk of bipolar disorder.

A recent large-scale study have reported that rs1063843, a single nucleotide polymorphism located in the CAMKK2 gene is highly associated with schizophrenia in European and Han Chinese populations. Increasing evidences show that schizophrenia and bipolar disorder have some common genetic variance. Here, we evaluated the association of this variant with schizophrenia and bipolar disorder in Iranian population.
