Bromodomain and PHD finger containing 1 ()-related neurodevelopmental disorder is characterized by intellectual disability, developmental delay, hypotonia, dysmorphic facial features, ptosis, and blepharophimosis. Both and inherited pathogenic variants have been previously reported in association with this disorder. We report two affected female siblings with a novel variant in c.

Abrogation of MAP4K4 protein function causes congenital anomalies in humans and zebrafish.

We report 21 families displaying neurodevelopmental differences and multiple congenital anomalies while bearing a series of rare variants in (). MAP4K4 has been implicated in many signaling pathways including c-Jun N-terminal and RAS kinases and is currently under investigation as a druggable target for multiple disorders. Using several zebrafish models, we demonstrate that these human variants are either loss-of-function or dominant-negative alleles and show that decreasing Map4k4 activity causes developmental defects.

Prepregnancy exposure to dietary arsenic and congenital heart defects.

Introduction: Arsenic crosses the placenta and accumulates in fetal tissues. In the United States, diet is the predominant route of arsenic exposure, but epidemiologic data are sparse regarding this exposure and development of birth defects. Using data from a large case-control study, we explored associations between maternal dietary arsenic exposure and congenital heart defects (CHDs), the most prevalent birth defects.

Co-occurrence of and Pathogenic Variants: A Case Report.

Von Hippel Lindau(VHL)syndrome presents with cerebellar and spinal hemangioblastomas, renal cell cancer, neuroendocrine pancreatic tumor, and pheochromocytoma and it is caused by germline mutations in the gene. Pathogenic germline variants in the succinate dehydrogenase A () gene are associated with paraganglioma and pheochromocytoma. Here we report co-occurrence of germline pathogenic variants in both and genes in a patient who presented with pancreatic neuroendocrine tumor.

Maternal cigarette smoking and alcohol consumption and congenital diaphragmatic hernia.

Background: Congenital diaphragmatic hernia (CDH) occurs when abnormal diaphragm development allows herniation of abdominal organs into the thoracic cavity. Its etiopathogenesis is not well understood, but cigarette smoking and alcohol exposure may impact diaphragm development. Using data from a large, population-based case-control study, we examined associations between maternal cigarette smoking and alcohol consumption and CDH in offspring.

Discovery of a neuromuscular syndrome caused by biallelic variants in .

Activating Signal Cointegrator 1 Complex, Subunit 3 (ASCC3) is part of the four-part ASC-1 transcriptional cointegrator complex. This complex includes ASCC1 (associated with spinal muscular atrophy with congenital bone fractures 2), TRIP4 (associated with spinal muscular atrophy with congenital bone fractures 1), and ASCC2 (not yet associated with human disease.) encodes a DNA helicase responsible for generating single-stranded DNA as part of the DNA damage response.

Interstitial duplication of 20q11.22q13.11: A case report and review of literature.

Evidence for Increased Response to Induced Endoplasmic Reticulum Stress in Myeloid Cells in Acquired Aplastic Anemia.

Autoimmune response targeting the hematopoietic stem cells highlights the current understanding of acquired aplastic anemia (AAA) pathogenesis. Upregulation of the unfolded protein response is the cell's rejoinder to a variety of stresses, which either result in restoring homeostasis or cell death by increased expression of the transcription factor C/EBP homologous protein. We hypothesized that there is an inherent increased sensitivity to various cellular stressors, including the ones that target endoplasmic reticulum (ER) in AAA leading to a decreased proliferation and potentially contributing to susceptibility to autologous cytotoxicity.

Borrelidin Induces the Unfolded Protein Response in Oral Cancer Cells and Chop-Dependent Apoptosis.

Oral squamous cell carcinoma (OSCC) is the most common cancer affecting the oral cavity, and US clinics will register about 30,000 new patients in 2015. Current treatment modalities include chemotherapy, surgery, and radiotherapy, which often result in astonishing disfigurement. Cancers of the head and neck display enhanced levels of glucose-regulated proteins and translation initiation factors associated with endoplasmic reticulum (ER) stress and the unfolded protein response (UPR).

Mutations in ARID2 are associated with intellectual disabilities.

The etiology of intellectual disabilities (ID) remains unknown for the majority of patients. Due to reduced reproductive fitness in many individuals with ID, de novo mutations account for a significant portion of severe ID. The ATP-dependent SWI/SNF chromatin modifier has been linked with neurodevelopmental disorders including ID and autism.

Genetic and functional studies reveal a novel noncoding variant in GALT associated with a false positive newborn screening result for galactosemia.

Background: Classic galactosemia (CG) is a potentially lethal genetic disorder that results from profound loss of galactose-1-phosphate uridylyltransferase (GALT). CG is detected by newborn screening (NBS) in many countries; however, conclusive diagnosis can be complex due to broad and overlapping ranges of GALT activity. Molecular studies can also be complex due to allelic heterogeneity at the GALT locus.

Infantile adrenocortical tumor with an activating GNAS1 mutation.

Context: Pediatric adrenocortical tumors (ACTs) are rare and are frequently associated with tumor predisposition syndromes. Somatic GNAS1 mutations are associated with adrenocortical hyperplasia, but have not typically been reported in ACTs.

Objective: We report on genetic and histopathological findings in a 3-month-old infant presenting with a unilateral cortisol-producing ACT with malignant features.

FOXO1 stimulates ceruloplasmin promoter activity in human hepatoma cells treated with IL-6.

FOXO1, a member of the winged-helix family of transcription factors, is a ubiquitously expressed protein involved in regulating a variety of cellular processes including glucose homeostasis, apoptosis, cell cycle control, muscle differentiation, and angiogenesis. In addition to these biological functions, FOXO1 is a key player in the oxidative stress response by stimulating the expression of metal-containing anti-oxidant proteins such as manganese superoxide dismutase, selenoprotein P, and catalase. Evidence in the literature suggests that FOXO1 may also be capable of regulating the expression of the anti-oxidant protein Ceruloplasmin (Cp), a six-copper-containing protein synthesized and secreted mainly by the liver.

Isolation of putative FOXO1 genomic elements using an improved in vitro technique to isolate genomic regulatory sequences.

The regulation of gene expression drives many biological processes and alterations in normal regulation are integral in the development of the diseased state. Therefore, the ability to screen genomic DNA for direct targets of DNA binding proteins (DNA-BP) would provide valuable information about the mechanisms underlying these processes. At present chromatin immunoprecipitation (ChIP) and its variants are the primary methods for identifying regulatory elements.

Novel flanking DNA sequences enhance FOXO1a DNA binding affinity but do not alter DNA bending.

FOXO1A, a member of the forkhead winged-helix family of proteins is a transcription factor with proapoptotic activities and plays a significant role in insulin and growth factor signaling. As such, FOXO1A is insulin responsive and binds to the insulin response element (IRE). However, multiple forkhead family members with diverse biological functions are also known to bind to the IRE.
