Laparoscopic cholecystectomy (LC) is the standard treatment for gallbladder disease, offering less invasive treatment and quicker recovery. However, bile duct injury (BDI) remains a critical complication. Indocyanine green (ICG) fluorescence imaging has emerged as a valuable technique to improve biliary structure visualization and potentially reduce BDI during LC.

Article Synopsis
  • Disorders of somatic mosaicism (DoSMs) are rare genetic conditions that occur due to changes in cells after fertilization, and current guidelines for genetic variant interpretation are not well-suited for these disorders.* -
  • The Brain Malformations Variant Curation Expert Panel (BMVCEP) has adapted existing guidelines for brain-related DoSMs, but their applicability to other DoSM types is limited.* -
  • Researchers at Washington University have made modifications to the BMVCEP framework to enhance variant classification for broader DoSMs, which could lead to more accurate diagnoses and better clinical care.*

Article Synopsis
  • Neurodevelopmental disorders (NDDs) are often linked to rare genetic variations, yet standard genomic testing misses many clinically relevant variants, prompting the need for alternative analyses like examining "poison exons" (PEs).
  • The study involved curating RNA sequencing data to identify 1937 conserved PE regions relevant to NDDs and analyzing genetic variants across 2999 patients.
  • The researchers discovered six novel relevant variants, mostly in genes associated with epilepsy, demonstrating that including PE analysis can enhance diagnostic yields for NDDs with minimal additional effort.

Article Synopsis
  • Neurodevelopmental disorders (NDDs) can be linked to rare genetic variations, but standard genomic testing often misses key variants, particularly those in "poison exons" (PEs), which lead to premature termination of protein production.
  • Researchers analyzed RNA sequencing data and identified 1,937 conserved PE regions to assess the impact of specific genetic variants in NDD cohorts.
  • From nearly 3,000 individuals studied, six previously overlooked variants were found in PE regions that could explain certain NDDs, suggesting that including PE analysis could enhance diagnostic accuracy without significantly increasing the testing burden.

Article Synopsis
  • The rise of exome and genome sequencing has led to unexpected genetic findings, particularly in pediatric patients, creating challenges for labs and healthcare providers regarding whether to disclose these incidental findings.
  • A study involving 21 pediatric patients identified 23 non-ACMG-recommended incidental findings, revealing variability in how different research sites handle the return of these results.
  • Although sharing incidental findings can provide insights and benefits to patients, it also poses risks and burdens for healthcare providers, highlighting the need for established guidelines across labs.

Exome and genome sequencing have proven to be effective tools for the diagnosis of neurodevelopmental disorders (NDDs), but large fractions of NDDs cannot be attributed to currently detectable genetic variation. This is likely, at least in part, a result of the fact that many genetic variants are difficult or impossible to detect through typical short-read sequencing approaches. Here, we describe a genomic analysis using Pacific Biosciences circular consensus sequencing (CCS) reads, which are both long (>10 kb) and accurate (>99% bp accuracy).

The desire of parents to obtain a genetic diagnosis for their child with intellectual disability and associated symptoms has long been framed as a diagnostic odyssey, an arduous and sometimes perilous journey focused on the goal of identifying a cause for the child's condition. Semi-structured interviews (N = 60) were conducted with parents of children (N = 59, aged 2-24 years) with intellectual disability and/or developmental delay (IDD) who underwent genome sequencing at a single pediatric multispecialty clinic. Interviews were conducted after parents received their child's sequencing result (positive findings, negative findings, or variants of unknown significance).

Neurodevelopmental disorder with dysmorphic facies and distal limb anomalies (NEDDFL), defined primarily by developmental delay/intellectual disability, speech delay, postnatal microcephaly, and dysmorphic features, is a syndrome resulting from heterozygous variants in the dosage-sensitive bromodomain PHD finger chromatin remodeler transcription factor BPTF gene. To date, only 11 individuals with NEDDFL due to de novo BPTF variants have been described. To expand the NEDDFL phenotypic spectrum, we describe the clinical features in 25 novel individuals with 20 distinct, clinically relevant variants in BPTF, including four individuals with inherited changes in BPTF.

We report a case of sudden cardiovascular collapse several weeks following surgical repair of a traumatic diaphragmatic hernia. The patient presented with features of circulatory shock without a clear diagnosis, therefore an urgent computed tomography scan of the chest and abdomen was undertaken, which revealed a pericardial effusion with evidence of cardiac tamponade. Ultrasound-guided needle pericardiocentesis with aspiration of blood from the pericardial sac in the Emergency Department provided an immediate response and her cardiac output improved.
