Article Abstract
Pathogenic variants in IGHMBP2 have been associated with spinal muscular atrophy with respiratory distress type 1 (SMARD1) and Autosomal Recessive Charcot-Marie-Tooth disease type 2S (AR-CMT2S), as well as a relatively wide spectrum of rare, atypical phenotypes. We describe clinical and molecular features of five patients who have diverse clinical findings associated with known and novel IGHMBP2 pathogenic variants. Genotype-phenotype correlations are evident, highlighting the association of specific variants with SMARD1 or AR-CMT2S. This study expands the spectrum of the IGHMBP2-related disease and highlights the necessity to study diverse populations to enhance diagnostic accuracy and refine genotype-phenotype correlations.

Purpose: Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) is a rare cancer susceptibility syndrome exclusively attributable to pathogenic variants in FH (HGNC:3700). This paper quantitatively weights the phenotypic context (PP4/PS4) of such very rare variants in FH.
Methods: We collated clinical diagnostic testing data on germline FH variants from 387 individuals with HLRCC and 1,780 individuals with renal cancer, and compared the frequency of 'very rare' variants in each phenotypic cohort against 562,295 population controls.

Dent disease is a rare X-linked recessive inherited renal tubular disorder characterized by low molecular weight proteinuria (LMWP), hypercalciuria, nephrocalcinosis, and other clinical features, and can lead to progressive renal failure. It is primarily caused by mutations in the gene. This article reports the case of a 10-year-old male patient of Chinese descent who was incidentally found to have asymptomatic proteinuria during a routine health examination.

Superinfection exclusion (SIE) is a finely tuned virus-virus interaction mechanism closely linked to the viral infection cycle. However, the mechanistic basis of SIE remains incompletely understood in plant viruses, particularly among negative-sense, single-stranded RNA viruses. In this study, we first describe the development of an efficient reverse genetics system for the plant nucleorhabdovirus Physostegia chlorotic mottle virus (PhCMoV) by codon optimisation of the large polymerase coding sequence.

Purpose: Multiple primary tumors arising in the same individual pose challenges for precision oncology, particularly in the context of hereditary cancer syndromes such as Lynch syndrome. While these tumors may originate from a shared germline predisposition, it remains unclear whether they also share somatic alterations that could be therapeutically exploited. This study aimed to characterize the extent of somatic genomic overlap between synchronous or metachronous gastric and colorectal cancers within young Korean patients.
