Article Synopsis
- Tatton-Brown-Rahman syndrome (TBRS) is a genetic disorder characterized by overgrowth, intellectual disability, and distinct facial features, resulting from mutations in a gene that regulates DNA methylation.* -
- A study of 24 French patients identified 17 new genetic variants, confirming that 100% showed intellectual disability, 96% had distinctive facial traits, and 87% exhibited overgrowth, alongside novel symptoms like hypertrichosis.* -
- The findings enhance the understanding of TBRS's clinical presentation, aiding in diagnosis and patient care by clarifying its genetic and phenotypic diversity.*
Background: Patients with decompensated cirrhosis experience high mortality rates. Current prognostic scores, including the model for end-stage liver disease (MELD), may underperform in settings other than in those they were initially developed. Novel biomarkers have been proposed to improve prognostication accuracy and even to predict development of complications.

- Variants of uncertain significance (VUS) present challenges in diagnosing rare diseases, and episignatures have emerged as potential biomarkers to help classify these variants.
- A study analyzed DNA methylation data from different groups, including carriers of pathogenic variants and healthy controls, using a k-nearest-neighbour classifier to assess the predictive abilities of various episignatures.
- Results revealed that while some signatures (ATRX, DNMT3A, KMT2D, NSD1) achieved 100% sensitivity, others (CREBBP-RSTS, CHD8) showed lower performance, indicating that not all episignatures are equally reliable for diagnostic use and highlighting the need for further validation with larger sample sizes.
Background & Aims: Nephrotoxicity of intravenous iodinated contrast media (ICM) in cirrhosis is still a debated issue, due to scarce, low-quality and conflicting evidence. This study aims to evaluate the incidence and predisposing factors of acute kidney injury (AKI) in patients with cirrhosis undergoing contrast-enhanced computed tomography (CECT).
Methods: We performed a prospective, multicenter, cohort study including 444 inpatients, 148 with cirrhosis (cohort 1) and 163 without cirrhosis (cohort 3) undergoing CECT and 133 with cirrhosis (cohort 2) unexposed to ICM.
