- Patients with suspected monogenic disorders often remain undiagnosed after exome sequencing. We report a family with two sisters affected by a complex spastic paraplegia. Initial exome sequencing had identified monoallelic pathogenic nonsense variants in and , subunits of the adaptor protein complex 4 (AP-4), suggesting digenic inheritance. As digenic inheritance has not been established for AP-4-associated disorders, we applied a multiomics approach including genome sequencing, RNA sequencing and proteomics to clarify the genetic cause. By RNA sequencing a predicted synonymous variant (NM_006594.5:c.969G > A), compound heterozygous to the nonsense variant in and previously considered as benign, was re-prioritized as aberrant splicing was demonstrated. Proteomics showed reduced abundance of AP-4 components AP4B1 and AP4M1 and an upregulation of the cargo protein ATG9A, confirming AP-4 deficiency. Although the variant resulted in nonsense-mediated decay, the identification of biallelic causative variants in established the diagnosis of monogenic "Spastic paraplegia 47, autosomal recessive" while the initial hypothesis of digenic inheritance was refuted. This study illustrates the value of multiomics approaches in the diagnostic workflow of rare diseases and the potential for pathogenicity of synonymous variants. - Source: PubMed

Autophagy has been implicated in immune regulation and inflammatory signaling in these conditions; however, its transcriptomic role in distinguishing sepsis from sepsis-induced ARDS remains incompletely defined. - Source: PubMed

Wang QinPeng YuanWang YongFangYang YanGu ChenWang JiajiaHuang Jianan - Understanding how selection shapes disease risk remains challenging. Variants influencing complex traits, including common diseases, can also impact fitness and thus be constrained by purifying selection. Consequently, genetic variance underlying disease susceptibility may be attributed to low-frequency, population-specific variants. We analyzed 509,817 genome-wide variants from 72,635 Han Taiwanese individuals to identify loci showing age-dependent allele frequency shifts that signal ongoing selection. After adjusting for potential age-related population structure, we detected 168 variants deviating from neutrality, with most showing declining frequencies in younger generations, consistent with purifying selection on deleterious alleles influencing disease risk. These variants were enriched for rare alleles (≤0.1%) and disease-associated variants. At BRCA1, we identified 16 rare pathogenic variants in strong linkage disequilibrium undergoing purifying selection that coexist with a positively selected haplotype, revealing temporally fluctuating selection; comparable patterns at BRCA2 and MLH1 suggest recurrent selective trade-offs in DNA repair genes. Phenome-wide association analysis across 30 hematologic and cardiometabolic traits linked a subset of candidates to increased erythrocyte volume and reduced hemoglobin concentration, suggesting subclinical physiological effects. These results demonstrate ongoing natural selection on disease-relevant variation, particularly affecting hematologic traits in the Han Taiwanese population, and highlight opportunities to refine precision-medicine risk models. - Source: PubMed

Two of the most-cited candidates, miR-29a-3p and miR-15b-5p, are predicted to bind both the viral genome and key entry/trafficking factors such as Furin and ATG9A, but functional evidence is fragmented and often contradictory. Here, we put both miRNAs to the test in human Calu-3 cells infected with the SARS-CoV-2 Beta and Omicron BA.1 variants, using parallel gain- and loss-of-function strategies coupled to RT-qPCR of viral and cellular transcripts and back-titration of infectious progeny on VeroE6/TMPRSS2 cells. Both miRNAs transiently suppressed viral gene expression at 6 hpi, but this early dampening was followed by a marked transcript rebound at 24 hpi, especially for Omicron, with virtually no impact on total extracellular viral RNA. More strikingly, miR-15b modulation enhanced infectious virus output during Beta infection, and miR-29a overexpression boosted Omicron BA.1 infectivity, while Furin, ATG9A, AKT3, and TFEB showed only modest, condition-dependent shifts. Rather than acting as clean antiviral effectors, miR-29a and miR-15b emerge as context-dependent modulators that can paradoxically favor SARS-CoV-2 replication-a cautionary signal for miRNA-based antiviral strategies. - Source: PubMed

If apoptotic cells are not efficiently removed by phagocytes, they progress to secondary necrosis when the plasma membrane (PM) becomes permeabilised and release proinflammatory damage-associated molecular patterns (DAMPs) such as HMGB1 and ATP, which drive inflammation and contribute to autoimmune diseases. Thus, controlling inflammation through maintaining PM integrity is critical, however the molecular mechanisms underpinning this is not well defined. Here, we reveal a calcium-dependent process that delays secondary necrosis by promoting PM repair. Mechanistically, calcium influx through T-type voltage-gated calcium channels mediates the recruitment of the lipid scramblase ATG9A and Golgi components to damaged PM regions, thereby preventing early cellular lysis and DAMP release. Inhibition of calcium influx or loss of ATG9A accelerates PM rupture, increases DAMP secretion, and exacerbates inflammatory cell recruitment in vivo. Taken together, this study establishes a novel role for T-type calcium channels and ATG9A in regulating PM repair during apoptosis and highlights their therapeutic potential for controlling unwanted inflammation. - Source: PubMed
