Mutations in transmembrane protein 230 (TMEM230) have recently been reported to be associated with Parkinson's disease (PD) in a North American population. A highly prevalent mutation, c.550_552delTAGinsCCCGGG (p.*184ProGlyext*5) was found in 3.1% of Chinese familial PD patients. However, subsequent studies failed to replicate these findings in different populations. Our objective was to confirm the role of this gene in a large number of PD patients and controls in a Taiwanese population. Among 1,672 participants, we sequenced all coding exons and exon-intron boundary junctions of the TMEM230 gene in 180 probands with familial PD...

REVIEW
Andreas Puschmann
PURPOSE OF REVIEW: This article reviews was to review genes where putative or confirmed pathogenic mutations causing Parkinson's disease or Parkinsonism have been identified since 2012, and summarizes the clinical and pathological picture of the associated disease subtypes. RECENT FINDINGS: Newly reported genes for dominant Parkinson's disease are DNAJC13, CHCHD2, and TMEM230. However, the evidence for a disease-causing role is not conclusive, and further genetic and functional studies are warranted...

TMEM230 gene mutations have been reported to be linked with Parkinson's disease (PD) recently. To investigate the prevalence of this gene in southeastern Chinese patients with PD, whole exome sequencing was performed in young-onset and familial PD patients and healthy controls in our Asian population. One heterozygous missense p.Phe121Ser mutation was detected in a healthy 76-year-old control subject and no other TMEM230 mutations were found in PD patients and controls. These data suggest that TMEM230 mutation might be a rare cause of Chinese familial and sporadic PD patients and a larger sample size will be needed to evaluate the association of TMEM230 polymorphic variants with PD...

Mutations in the transmembrane protein 230 (TMEM230) gene were recently identified in a large Canadian pedigree and 7 smaller Chinese families, nominating TMEM230 as the third gene causing a Mendelian form of late onset Parkinson's disease (PD) with typical Lewy-body pathology (after synuclein alpha (SNCA) and leucine rich repeat kinase 2 (LRRK2)). The protein encoded by TMEM230 remains largely uncharacterized, but initial evidence points to roles in the trafficking of recycling vesicles, retromers, and endosomes, suggesting intriguing links to the pathways targeted by other PD-causing genes...

During embryonic development, new arteries, and veins form from preexisting vessels in response to specific angiogenic signals. Angiogenic signaling is complex since not all endothelial cells exposed to angiogenic signals respond equally. Some cells will be selected to become tip cells and acquire migration and proliferation capacity necessary for vessel growth while others, the stalk cells become trailer cells that stay connected with pre-existing vessels and act as a linkage to new forming vessels. Additionally, stalk and tip cells have the capacity to interchange their roles...

Transmembrane Protein 230 (TMEM230) is a newly identified protein associated with Parkinson's disease (PD) found in Lewy bodies and Lewy neurites of patients with PD or dementia with Lewy body disease. However, TMEM230 has not yet been investigated in the most common neurodegenerative disorder, Alzheimer's disease (AD). Here, we demonstrate that the expression of TMEM230 is specifically increased in neurons in AD patients. Importantly, both granulovacuolar degeneration (GVD) and dystrophic neurites (DNs), two prominent characteristic pathological structures associated with AD, contain TMEM230 aggregates...

A study on familial Parkinson disease (PD) described 4 variants in the gene TMEM230 (Chr. 20p13) as the cause of PD. The aim of this study was to test if variants in the TMEM230 gene are associated with PD in 2 independent American European data sets. No variants in the TMEM230 region were found associated with PD, age at onset, or cerebrospinal fluid α-synuclein levels.

Mutations in the gene encoding the transmembrane protein 230 (TMEM230) have been reported in patients with familial, autosomal dominant inherited Parkinson's disease (ADPD). The aim of the present study was to explore the role and the prevalence of TMEM230 mutations in Chinese patients with ADPD. A cohort of 120 patients with ADPD and 650 healthy controls (HCs) from the Department of Neurology, West China Hospital of Sichuan University was screened. The entire coding exons of TREM230 in all the patients, as well as exon 5 of this gene in the 650 HCs, were directly sequenced with the Sanger sequencing approach...

TMEM230 mutations have been recently reported to cause autosomal dominant Parkinson's disease (PD). However, there are limited studies from different ethnic populations to support the role of TMEM230 in sporadic PD. In this study, we performed a comprehensive TMEM230 mutation screening in 550 sporadic PD patients and 560 controls to elaborate the genetic contribution of TMEM230 to sporadic PD. Overall, we did not find any pathogenic mutations in the coding sequence, while we identified four variants (c.68 + 182G > A, c...

TMEM230 is a newly identified Parkinson's disease (PD) gene encoding a transmembrane protein whose cellular and pathogenic roles remain largely unknown. Here, we demonstrate that loss of TMEM230 disrupts retromer cargo CI-M6PR (cation-independent mannose 6-phosphate receptor) trafficking and autophagic cargo degradation rates. TMEM230 depletion further inhibits extracellular secretion of the autophagic cargo p62 and immature lysosomal hydrolases in Golgi-derived vesicles leading to their intracellular accumulation, and is specifically mediated by loss of the small GTPase Rab8a...

Mutations in six genes are known to cause Parkinson's disease (PD) (autosomal dominant: alpha-synuclein, LRRK2, VPS35 and autosomal recessive: Parkin, PINK1 and DJ1) and number of other genes are implicated. In a recent article Deng and colleagues studied a large four generation American family of European descent and linked mutations in a novel gene, transmembrane-protein 230 gene (TMEM230) with lewy body confirmed PD. The authors demonstrated that pathogenic TMEM230 variants in primary mouse neurons affected movement of synaptic vesicles suggesting that TMEM230 may slow vesicular transport...

Mutations in TMEM230 have recently been associated to Parkinson's disease (PD). To further understand the role of this gene in the Caucasian population, we interrogated our large repository of next generation sequencing data from unrelated PD cases and controls, as well as multiplex families with autosomal dominant PD. We identified 2 heterozygous missense variants in 2 unrelated PD cases and not in our control database (p.Y106H and p.I162V), and a heterozygous missense variant in 2 PD cases from the same family (p...

Mutations in TMEM230 were identified as a genetic factor for Parkinson's disease (PD) with typical clinical symptoms and Lewy bodies in a North American population, and a highly prevalent TMEM230 mutation, c.550_552delTAGinsCCCGGG (p.*184ProGlyext*5), was found in 7 Chinese families. In the present study, we investigated the prevalence of TMEM230 mutations in a large cohort of Chinese PD patients and healthy controls individuals from mainland China. We sequenced all exons and exon-intron boundaries of TMEM230 in Chinese Han population including 1235 patients with PD and 1252 healthy control individuals...

Parkinson's disease is the second most common neurodegenerative disorder without effective treatment. It is generally sporadic with unknown etiology. However, genetic studies of rare familial forms have led to the identification of mutations in several genes, which are linked to typical Parkinson's disease or parkinsonian disorders. The pathogenesis of Parkinson's disease remains largely elusive. Here we report a locus for autosomal dominant, clinically typical and Lewy body-confirmed Parkinson's disease on the short arm of chromosome 20 (20pter-p12) and identify TMEM230 as the disease-causing gene...
