encodes a human long noncoding RNA (lncRNA) adjacent to , a coding gene in which de novo loss-of-function variants cause developmental and epileptic encephalopathy. Here, we report our findings in three unrelated children with a syndromic, early-onset neurodevelopmental disorder, each of whom had a de novo deletion in the locus. The children had severe encephalopathy, shared facial dysmorphisms, cortical atrophy, and cerebral hypomyelination - a phenotype that is distinct from the phenotypes of patients with haploinsufficiency.

Elevated sVCAM1 levels have been found to be associated with poor cardiovascular disease (CVD) outcomes, supporting VCAM1's role as a potential diagnostic marker and therapeutic target.

Evidence suggests that individuals with breakthrough infections, though rare and expected, may readily transmit COVID-19 to unvaccinated populations, posing a continuing threat to the unvaccinated. Here, we examine factors contributing to breakthrough infections including a poor immune response to the vaccines due to the fact of advanced age and underlying comorbidities, the natural waning of immune protection from the vaccines over time, and viral variants that escape existing immune protection from the vaccines.

The case presented here is based on a serotonin syndrome (SS) diagnosis, precipitated by newly prescribed tramadol in conjunction with previously prescribed serotonergic medications. A 79-year-old woman receiving combined citalopram and trazodone for major depressive disorder alongside oxycodone for chronic pain developed generalized weakness, tremors, altered mentation, episodic auditory and visual hallucinations, fever, tachypnea, tachycardia, and diaphoresis a few days after tramadol was prescribed for pain.

EHF controls many key processes in lung epithelial function so its regulatory mechanisms are important. Using CRISPR/Cas9 technology, we removed three key cis-regulatory elements (CREs) from the chr11p13 region and also activated multiple open chromatin sites with CRISPRa in airway epithelial cells.

The chromodomain helicase DNA-binding (CHD) family of proteins are ATP-dependent chromatin remodelers that contribute to the reorganization of chromatin structure and deposition of histone variants necessary to regulate gene expression. CHD proteins play an important role in neurodevelopment, as pathogenic variants in , , , and have been associated with a range of neurological phenotypes, including autism spectrum disorder (ASD), intellectual disability (ID) and epilepsy. Pathogenic variants in are associated with developmental epileptic encephalopathy (DEE) in humans, however little is known about how these variants contribute to this disorder.

Genome-wide association studies (GWAS) previously identified additional genomic sites associated with CF lung disease severity. One of these, at chromosome 11p13, is an intergenic region between Ets homologous factor (EHF) and Apaf-1 interacting protein (APIP).

LTBP4 was identified as a genetic modifier of muscular dystrophy in mice and humans. An in-frame insertion polymorphism in the murine Ltbp4 gene associates with partial protection against muscular dystrophy.
View Article and Find Full Text PDFLatent TGFβ binding proteins are extracellular matrix proteins that bind latent TGFβ to form the large latent complex. Nonsynonymous polymorphisms in LTBP4, a member of the latent TGFβ binding protein gene family, have been linked to several human diseases, underscoring the importance of TGFβ regulation for a range of phenotypes. Because of strong linkage disequilibrium across the LTBP4 gene, humans have two main LTBP4 alleles that differ at four amino acid positions, referred to as IAAM and VTTT for the encoded residues.

Genetic diagnosis now frequently pinpoints the primary mutation responsible for a given neuromuscular disease. However, the results from genetic testing indicate that neuromuscular disease phenotypes may vary widely, even in individuals with the same primary disease-causing mutation.

We found that CACNA1A coordinates gene expression using a bicistronic mRNA bearing a cryptic internal ribosomal entry site (IRES). The first cistron encodes the well-characterized α1A subunit.

Ltbp4, encoding latent transforming growth factor-β binding protein 4, was previously discovered in a genome-wide scan as a modifier of murine muscular dystrophy. We sought to determine whether LTBP4 genotype influenced DMD severity in a large patient cohort.

Patients And Methods: We retrospectively reviewed patients receiving ADT for prostate cancer at our institution between January 1989 and July 2005; those receiving only neoadjuvant ADT were excluded. Variables included age, race, body mass index, prostate-specific antigen level before ADT, Gleason sum, clinical stage, ADT type (medical vs surgical) and schedule (continuous vs intermittent), previous treatment for prostate cancer, presence of pre-existing or new-onset diabetes mellitus (DM), and presence of ED before ADT.
In recent years, there has been a growing interest in the assessment of quality of life (QOL) issues, particularly in chronic debilitating conditions. Several instruments have been developed, tested, and validated in the general population and in other chronic diseases; however, few studies have examined QOL issues in adults with sickle cell disease (SCD). We developed Sickle Cell Impact Measurement Scale (SIMS), an instrument for measuring the QOL of adults with SCD.

PATIENTS AND METHODS We retrospectively reviewed patients receiving ADT for prostate cancer at our institution between January 1989 and July 2005; those with incomplete information and those receiving only neoadjuvant ADT were excluded. Variables examined included age, race, body mass index (BMI), pretreatment prostate-specific antigen, Gleason sum, clinical stage, ADT type (medical vs surgical) and schedule (continuous vs intermittent), presence of pre-existing DM, serum glucose and glycosylated haemoglobin (HbA1c) levels before and after ADT, and receipt of vitamin D or bisphosphonate supplementation.
