The transcription factor Zeb1 controls homeostasis and function of type 1 conventional dendritic cells.

Type 1 conventional dendritic cells (cDC1) are the most efficient cross-presenting cells that induce protective cytotoxic T cell response. However, the regulation of their homeostasis and function is incompletely understood. Here we observe a selective reduction of splenic cDC1 accompanied by excessive cell death in mice with Zeb1 deficiency in dendritic cells, rendering the mice more resistant to Listeria infection.

A gain-of-function TPC2 variant R210C increases affinity to PI(3,5)P and causes lysosome acidification and hypopigmentation.

Albinism is a group of inherited disorders mainly affecting skin, hair and eyes. Here we identify a de novo point mutation, p.R210C, in the TPCN2 gene which encodes Two Pore Channel 2 (TPC2) from a patient with albinism.

The potential of prodigiosin for control of Prorocentrum donghaiense blooms: Algicidal properties and acute toxicity to other marine organisms at various trophic levels.

Prorocentrum donghaiense, a marine dinoflagellate, causes harmful algal blooms (HABs) characterised by the highest outbreak frequency and most extensive coverage among similar species in the East China Sea. Highly efficient and ecofriendly biocontrol strategies should be developed for HAB control. Prodigiosin is an efficient biological algicide that demonstrated strong algicidal activity towards P.

Polymerase chain reaction-based assays facilitate the breeding and study of mouse models of Klinefelter syndrome.

Klinefelter syndrome (KS) is one of the most frequent genetic abnormalities and the leading genetic cause of nonobstructive azoospermia. The breeding and study of KS mouse models are essential to advancing our knowledge of the underlying pathological mechanism. Karyotyping and fluorescence in situ hybridization are reliable methods for identifying chromosomal contents.

A Rare Novel Variation and Risk of Gilles de la Tourette Syndrome: Whole-Exome Sequencing in a Multiplex Family and a Follow-Up Study in a Chinese Population.

Rare inherited variations in multiplex families with Gilles de la Tourette syndrome (GTS) are suggested to play an important role in the genetic etiology of GTS. In order to explore the rare inherited variations with the risk of GTS, whole-exome sequencing (WES) was performed in a family with three affected patients with GTS. Among the five novel rare variations identified by WES, G161S was presented in three patients, but not in four unaffected individuals, and thus co-segregated with GTS.

Clinical Utility of a High-Resolution Melting Test for Screening Numerical Chromosomal Abnormalities in Recurrent Pregnancy Loss.

Recurrent pregnancy loss (RPL) occurs in approximately 5% of clinically identified pregnancies. Determining the cause of RPL is essential. Genetic testing, accompanied by an evidence-based workup, is the well-accepted process for evaluating RPL; however, current genetic tests have limitations in clinical practice.

De novo truncating variant in NSD2gene leading to atypical Wolf-Hirschhorn syndrome phenotype.

Background: Wolf-Hirschhorn syndrome (WHS) is a contiguous gene syndrome caused by partial 4p deletion highly variable in size in individual patients. The core WHS phenotype is defined by the association of growth delay, typical facial characteristics, intellectual disability and seizures. The WHS critical region (WHSCR) has been narrowed down and NSD2 falls within this 200 kb region.

A Novel c.676_677insG Mutation in Congenital Central Hypoventilation Syndrome.

() is considered to be the causative gene of congenital central hypoventilation syndrome (CCHS), a dominant genetic disorder that results in abnormal central respiratory control with resulting hypoventilation during sleep. In this study, we report a novel c.676_677insG (p.

Carrier screening for spinal muscular atrophy with a simple test based on melting analysis.

Carrier screening of spinal muscular atrophy (SMA) can provide reproductive options for carriers and prevent the birth defects. Here, we developed a simple screening test based on melting analysis. The test comprises a duplex PCR with two primer pairs and three probes to simultaneous amplify SMN1, SMN2, and CFTR.

Clinical phenotype, in silico and biomedical analyses, and intervention for an East Asian population-specific c.370G>A (p.G124S) COQ4 mutation in a Chinese family with CoQ10 deficiency-associated Leigh syndrome.

COQ4 mutations have recently been shown to cause a broad spectrum of mitochondrial disorders in association with CoQ10 deficiency. Herein, we report the clinical phenotype, in silico and biochemical analyses, and intervention for a novel c.370 G > A (p.

Evaluation of a Magnetic Cellulose-Based DNA Extraction System to Improve the Performance of HybriBio Human Papillomavirus Genotyping and Screening Tests for Cervical Swab Samples.

Background: To ensure the accuracy of clinical human papillomavirus (HPV) testing, the nucleic acid extraction procedure should be thoroughly evaluated for each clinical sample type. Therefore, we evaluated whether the MagCore® Automated Nucleic Acid Extraction system (MagCore system) could improve HybriBio HPV test performance for cervical swab samples.

Methods: We compared the performance of HybriBio HPV genotyping and screening tests using samples prepared with the MagCore system and Cell Lysis Kit, which was provided by the HPV test manufacturer.

Whole Exome Sequencing Identifies a c.C2566T Mutation in the Androgen Receptor in a Chinese Family.

Background: Whole exome sequencing (WES) is one of the most valuable tools for the detection of Mendelian diseases in clinical laboratory. We performed WES for a family of 46,XY disorders of gender development and compared the applicability of public databases for the subsequent phenotype studies of WES-identified mutations.

Methods: DNA samples from the two patients were analyzed by WES.
