The 40S ribosomal subunit recycling pathway is an integral link in the cellular quality control network, occurring after translational errors have been corrected by the ribosome-associated quality control (RQC) machinery. Despite our understanding of its role, the impact of translation quality control on cellular metabolism remains poorly understood. Here, we reveal a conserved role of the 40S ribosomal subunit recycling (USP10-G3BP1) complex in regulating mitochondrial dynamics and function.

Joubert Syndrome (JS) is a congenital cerebellar ataxia typically inherited in an autosomal recessive pattern, although rare X-linked inheritance can occur. It is characterized by hypotonia evolving into ataxia, global developmental delay, oculomotor apraxia, breathing dysregulation, and multiorgan involvement. To date, there are 40 causative genes implicated in JS, all of which encode proteins of the primary cilium.

Polygenic prediction of complex trait phenotypes has become important in human genetics, especially in the context of precision medicine. Recently, mr.mash, a flexible and computationally efficient method that models multiple phenotypes jointly and leverages sharing of effects across such phenotypes to improve prediction accuracy, was introduced.

Article Synopsis
  • Variants associated with neurodevelopmental impairments in children are complex and challenging to evaluate due to their diverse nature and unclear causes.
  • The study highlights a case of a child with neonatal-onset epilepsy and a specific genetic variant (G256W) that impacts ion channel function and leads to reduced cell stability and conduction in nervous tissue.
  • The research also establishes a mouse model that exhibits epilepsy and hyperexcitability in brain cells, linking the genetic variant to observable neurological behaviors and suggesting potential wider implications for understanding similar conditions in other patients.

Inherited genetics represents an important contributor to risk of esophageal adenocarcinoma (EAC), and its precursor Barrett's esophagus (BE). Genome-wide association studies have identified ∼30 susceptibility variants for BE/EAC, yet genetic interactions remain unexamined. To address challenges in large-scale G×G scans, we combined knowledge-guided filtering and machine learning approaches, focusing on genes with (A) known/plausible links to BE/EAC pathogenesis (n=493) or (B) prior evidence of biological interactions (n=4,196).

Hyperparathyroidism-jaw tumor syndrome is a rare form of syndromic primary hyperparathyroidism. We describe a young female with a history of common precursor B acute lymphoblastic leukaemia who was diagnosed with overt primary hyperparathyroidism due to a pathogenic CDC73 variant (c.25C > T).

A Drosophila Model of Mucopolysaccharidosis IIIB.

Genetics

December 2024

Department of Genetics and Biochemistry and Center for Human Genetics, Clemson University, 114 Gregor Mendel Circle, Greenwood, SC 29646, USA.

Article Synopsis
  • MPS IIIB is a rare disorder caused by defects in the enzyme NAGLU, leading to brain dysfunction due to the accumulation of heparan sulfate in lysosomes.
  • Researchers created a Drosophila (fruit fly) model with various NAGLU mutations to study the disorder's effects on activity and sleep patterns, revealing significant hyperactivity and sleep issues.
  • The study found that gene expression changes in mutant flies are linked to problems with nervous system development and synaptic function, suggesting that this fly model could help develop future therapies for MPS IIIB.

Courses of SARS-CoV-2 infections are highly variable, ranging from asymptomatic to lethal COVID-19. Though research has shown that host genetic factors contribute to this variability, cohort-based joint analyses of variants from the entire allelic spectrum in individuals with confirmed SARS-CoV-2 infections are still lacking. Here, we present the results of whole genome sequencing in 1,220 mainly vaccine-naïve individuals with confirmed SARS-CoV-2 infection, including 827 hospitalized COVID-19 cases.

Skeletal dysplasias are a clinically and genetically heterogeneous group of rare disorders. Studies from large cohorts are essential to provide insights into the disease epidemiology, phenotypic spectrum, and mutational profiles. Here we enumerate additional 248 Indians from 197 families with a skeletal dysplasia, following a similar study earlier.

  • SNPs linked to chronic kidney disease (CKD) show different impacts on urinary uromodulin levels in Black and White populations, with unknown factors in African groups.
  • Clinical studies involving young and middle-aged adults reveal that Black individuals have lower uromodulin levels and higher prevalence of CKD-risk SNPs compared to Whites.
  • Findings highlight significant ethnic variations in genetic and clinical factors affecting uromodulin, suggesting the need for tailored approaches in kidney function research and medicine.

  • The study explores the biological differences linked to PTSD by examining DNA methylation changes in blood, suggesting they could indicate susceptibility or effects of trauma.
  • Conducted by the Psychiatric Genomics Consortium, the research included nearly 5,100 participants to identify specific genetic markers associated with PTSD.
  • Results showed 11 significant CpG sites related to PTSD, with some also showing correlations between blood and brain tissue methylation, highlighting their potential role in understanding PTSD biology.

Article Synopsis
  • MUC1 and UMOD pathogenic variants are linked to autosomal dominant tubulointerstitial kidney disease (ADTKD), with MUC1 associated with a significant reduction in mucin-1 production.
  • A survey conducted among ADTKD patients revealed that those with ADTKD-MUC1 had a higher rate of previous COVID-19 infections and COVID-related deaths compared to ADTKD-UMOD individuals.
  • The study concluded that individuals with ADTKD-MUC1 are eight times more likely to die from COVID-19, suggesting that lower mucin-1 levels may contribute to this increased risk.

Natural selection on complex traits is difficult to study in part due to the ascertainment inherent to genome-wide association studies (GWAS). The power to detect a trait-associated variant in GWAS is a function of frequency and effect size - but for traits under selection, the effect size of a variant determines the strength of selection against it, constraining its frequency. Recognizing the biases inherent to GWAS ascertainment, we propose studying the joint distribution of allele frequencies across populations, conditional on the frequencies in the GWAS cohort.

Opioid use disorder (OUD) affects millions of people worldwide. While it is known that OUD originates from many factors, including social and environmental factors, the role of genetic variants in developing the disease has also been reported. This study aims to investigate the genetic variants associated with the risk of developing OUD upon exposure.

Genomic and transmission dynamics of the 2024 Marburg virus outbreak in Rwanda.

Nat Med

Rwanda Joint Task Force for Marburg Virus Disease Outbreak, Ministry of Health, Rwanda Biomedical Centre, Kigali, Rwanda.

The ongoing outbreak of Marburg virus disease in Rwanda marks the third largest historically, although it has shown the lowest fatality rate. Genomic analysis of samples from 18 cases identified a lineage with limited internal diversity, closely related to a 2014 Ugandan case. Our findings suggest that the Rwandan lineage diverged decades ago from a common ancestor shared with diversity sampled from bats in Uganda.

Purpose: In parent-child trios with genome sequencing data, we investigated inherited biallelic deletions to identify known and novel genetic disorders.

Methods: We developed a copy-number variations analysis pipeline based on autosomal genome sequencing read depth of Genomics England 100,000 Genomes Project data from 11,754 parent-child trios and additional 18,875 non-trios. A control cohort of 15,440 cancer patients provided independent deletion frequencies.
