Next-generation sequencing (NGS) is widely used to identify the causative mutations underlying diverse human diseases, including cancers, which can be useful for discovering the diagnostic and therapeutic targets. Currently, a number of single-nucleotide variant (SNV)-calling algorithms are available; however, there is no tool for visualizing the recurrent and phenotype-specific mutations for general researchers. In this study, in order to support defining the recurrent mutations or phenotype-specific mutations from NGS data of a group of cancers with diverse phenotypes, we aimed to develop a user-friendly tool, named mutation arranger for defining phenotype-related SNV (MAP). MAP is a user-friendly program with multiple functions that supports the determination of recurrent or phenotype-specific mutations and provides graphic illustration images to the users. Its operation environment, the Microsoft Windows environment, enables more researchers who cannot operate Linux to define clinically meaningful mutations with NGS data from cancer cohorts.

Haploinsufficiency of A20 (HA20), caused by mutations, is a rare autoinflammatory syndrome characterized by highly variable, multisystem manifestations that often delay recognition and definitive care. The A20 protein restrains NF-κB-mediated pro-inflammatory signaling; therefore, loss-of-function variants unleash widespread inflammation that can involve virtually any organ. Fewer than 200 cases have been reported worldwide; thus, clinicians have limited phenotype-specific guidance.

Multi-phenotype deep mutational scanning (DMS) experiments provide a powerful means to dissect how protein variants affect different layers of molecular function, such as abundance, surface expression, and ligand binding. When these phenotypes are connected through a molecular pathway, interpreting variant effects becomes challenging because downstream phenotypes often reflect both direct and indirect consequences of mutation. We introduce Cosmos, a Bayesian framework for residue-level causal inference in multi-phenotype DMS data.

Despite mounting evidence for shared genetic risk across TDP-43 proteinopathies, the modifiers of individual-level traits are unknown. We aimed to identify polygenic contributions to trait heterogeneity across TDP-43 proteinopathies.

This study investigated the effects of feature augmentation, which uses generated images with specific imaging features, on the performance of isocitrate dehydrogenase (IDH) mutation prediction models in gliomas. A total of 598 patients were included from our institution (310 training, 152 internal test) and the Cancer Genome Atlas (136 external test). Score-based diffusion models were used to generate T2-weighted, FLAIR, and contrast-enhanced T1-weighted image triplets.

Background: Mycobacterium abscessus (Mabs) pulmonary disease (Mabs-PD) is difficult to treat, particularly in subspecies abscessus (Mabs-a), usually harboring macrolide-resistant sequevars, unlike subspecies massiliense (Mabs-m). The relationship between Mabs genetic variants and clinical features remains largely unexplored.
Methods: In this retrospective cohort study, patients with Mabs-PD and Mabs extrapulmonary disease (Mabs-ED), identified during 2016-2018, were observed for severe or progressive Mabs-PD, indicated by antibiotic needs or increased lung lesions.
