Article Synopsis
  • Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease, and this study investigated the role of transposable elements (TEs) in its development, which has not been extensively studied before.
  • By analyzing RNA-seq data from 198 SLE patients and 84 healthy controls, the researchers identified distinct groups based on TE expression levels, revealing connections to interferon (IFN) pathways and abnormal immune cell compositions.
  • The study concluded that heightened TE expression could be a key factor in SLE, potentially driving the activation of interferon pathways and contributing to abnormal immune responses.

Transcriptomic analysis plays a vital role in investigating Systemic Lupus Erythematosus (SLE), a complex autoimmune disease characterized by diverse clinical manifestations. This approach has yielded valuable insights into gene expression patterns and molecular regulatory mechanisms involved in SLE pathogenesis. Notably, interferon-stimulated gene (ISG) signatures are significantly upregulated in immune cells, skin, and kidney.

Article Synopsis
  • The study investigates gene expression patterns in Systemic Lupus Erythematosus (SLE) patients, focusing on those in remission and identifying abnormal pathways.
  • Researchers performed RNA-sequencing on blood samples from patients with varying disease activity and analyzed the differences in gene expression, finding that certain immune responses remained active even during remission.
  • The results suggest potential targets for drug repurposing to prevent disease flare-ups by understanding persistent gene signatures in remission patients, which could improve treatment approaches.

Objectives: Systemic lupus erythematosus (SLE) is a complex autoimmune disease with varying symptoms and multi-organ damage. Relapse-remission cycles often persist for many patients for years with the current treatment. Improved understanding of molecular changes caused by SLE flare and intensive treatment may result in more targeted therapies.

Currently, there are still many challenges in prenatal diagnosis, such as limited or uncertain fetal phenotyping, variant interpretation, and rapid turnaround times. The aim of this study was to illustrate the value of a comprehensive genomic evaluation in prenatal diagnosis. We retrospectively reviewed 20 fetuses with clinically significant copy number variants (CNVs) detected by chromosomal microarray analysis (CMA) and no further exome sequencing testing in our tertiary center between 2019 and 2020.

Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an autosomal-dominant systemic vascular disease that primarily involves small arteries. Patients with CADASIL experience migraines, recurrent ischemic strokes, cognitive decline, and dementia. The gene, which is located on chromosome 19p13.

Balanced chromosomal abnormalities (BCAs) are the most common chromosomal abnormalities and the frequency of congenital abnormalities is approximately twice as high in newborns with a BCA, but a prenatal diagnosis based on BCAs is subject to evaluation. To detect translocation breakpoints and conduct a prenatal diagnosis, we performed whole-genome sequencing (WGS) in 21 subjects who were found BCAs, 19 balanced chromosome translocations and two inversions, in prenatal screening. In 16 BCAs on non-N-masked regions (non-NMRs), WGS detected 13 (81.

Article Synopsis
  • Microsporidia are single-celled parasites that primarily infect honey bee gut cells, leading to issues like memory impairment and potential colony collapse.
  • The genome of these parasites was difficult to assemble due to high diversity, but researchers successfully re-sequenced it to produce an 8.8 Mbp assembly with 2,280 protein-coding genes, particularly those involved in nutrient transport and drug resistance.
  • The study reveals the loss of a crucial protein in many microsporidian species, providing insights into their biology and suggesting potential treatment strategies that target the parasite while preserving honey bee health.

The study of Mendelian diseases and the identification of their causative genes are of great significance in the field of genetics. The evaluation of the pathogenicity of genes and the total number of Mendelian disease genes are both important questions worth studying. However, very few studies have addressed these issues to date, so we attempt to answer them in this study.

Inherited retinal diseases (IRDs) are a common cause of visual impairment. IRD covers a set of genetically highly heterogeneous disorders with more than 150 genes associated with one or more clinical forms of IRD. Molecular genetic diagnosis has become increasingly important especially due to expanding number of gene therapy strategies under development.

Alagille syndrome (AGS) is a highly variable, autosomal dominant disease that affects multiple structures including the liver, heart, eyes, bones and face. Targeted region capture sequencing focuses on a panel of known pathogenic genes and provides a rapid, cost‑effective and accurate method for molecular diagnosis. In a Chinese family, this method was used on the proband and Sanger sequencing was applied to validate the candidate mutation.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a very rare genetic cardiac channelopathy, which has not been sufficiently studied yet. The first clinical manifestation has been described during the first decade of life, linked to strenuous exercise or acute emotion. The absence of structural heart disease and a family history of possible arrhythmogenic disorder generally guide the diagnosis towards a potential channelopathy.

Brugada syndrome is a primary arrhythmic syndrome that accounts for 20% of all sudden cardiac death cases in individuals with a structurally normal heart. Pathogenic variants associated with Brugada syndrome have been identified in over 19 genes, with SCN5A as a pivotal gene accounting for nearly 30% of cases. In contrast to other arrhythmogenic channelopathies (such as long QT syndrome), digenic inheritance has never been reported in Brugada syndrome.

Introduction: Core decompression is an efficient treatment for early stage ischemic necrosis of the femoral head. In conventional procedures, the pre-operative X-ray only shows one plane of the ischemic area, which often results in inaccurate drilling. This paper introduces a new method that uses computer-assisted technology and rapid prototyping to enhance drilling accuracy during core decompression surgeries and presents a validation study of cadaveric tests.

Background: Congenital cataract is a clinical and genetic heterogeneous group of eye disorders that causes visual impairment and childhood blindness. In this study, a Chinese family with congenital cataract is studied.

Methods: In order to identify the genetic defects which were associated with congenital cataract, a whole-exome sequencing approach is performed to screen for the potential mutation-causing disease.

Leigh syndrome is a subacute necrotising encephalomyopathy proven by post-mortem analysis of brain tissue showing spongiform lesions with vacuolation of the neuropil followed by demyelination, gliosis and capillary proliferation caused by mutations in one of over 75 different genes, including nuclear- and mitochondrial-encoded genes, most of which are associated with mitochondrial respiratory chain function. In this study, we report a patient with suspected Leigh syndrome presenting with seizures, ptosis, scoliosis, dystonia, symmetrical putaminal abnormalities and a lactate peak on brain MRS, but showing normal MRC enzymology in muscle and liver, thereby complicating the diagnosis. Whole exome sequencing uncovered compound heterozygous mutations in NADH dehydrogenase (ubiquinone) flavoprotein 1 gene (NDUFV1), c.

Familial hemophagocytic lymphohistiocytosis type 2 (FHL2), caused by perforin 1 (PRF1), is a genetic disorder of lymphocyte cytotoxicity that usually presents in the first 2 years of life and has a poor prognosis. Late onset of FHL2 has been sporadically reported, and the mechanism is largely unknown. A newly diagnosed FHL2 patient was detected to have compound mutations in both PRF1 alleles and positive Epstein-Barr virus (EBV) infection.
