Article Abstract
Objective: Erdheim-Chester disease (ECD) is rare histiocytosis with a wide range of clinical manifestations. Somatic mutations are key to the pathogenesis of the disease; however, the relationship between germline genetic variants and ECD has not been examined so far. The present study aims to explore the inherited genetic component of ECD by performing the first genome-wide association study.
Methods: After quality controls, a cohort of 255 patients with ECD and 7,471 healthy donors was included in this study. Afterward, a logistic regression followed by in silico functional annotation was performed.
Results: A signal at the 18q12.3 genomic region was identified as a new susceptibility locus for ECD (P = 2.75 × 10 ; Odds Ratio = 2.09). This association was annotated to the SETBP1 gene, which is involved in clonal haematopoiesis. Functional annotation of this region and of the identified suggestive signals revealed additional genes that could be potentially involved in the pathogenesis of the disease.
Conclusion: Overall, this work demonstrates that germline genetic variants can impact on the development of ECD and suggests new pathways with a potential pathogenic role.

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.
Intrapatient genomic divergence across multiple primary tumors in young Korean patients.

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.

Objective: This study investigates the association between alobar holoprosencephaly (HPE) and de novo germline microdeletions in the Xq25 region. To develop a Preimplantation Genetic Testing for Monogenic Disorders (PGT-M) based workflow enabling high-resolution preimplantation detection of sub-Mb microdeletions, overcoming the >1 Mb resolution limit of conventional whole genome amplification(WGA) copy number variation(CNV) sequencing to identify causative Xq25 variants and prevent pathogenic microdeletion transmission.
Methods: This study presents a clinical case involving a couple with an adverse obstetric history accompanied by two occurrences of HPE.

Accurate variant calling is essential for next-generation sequencing (NGS)-based diagnosis of rare diseases, yet most benchmarking studies have focused on standard cell lines or trio-based samples, with limited relevance to sporadic cases. Here, we systematically compared the performance of DeepVariant and GATK HaplotypeCaller in two Chinese cohorts of patients with sporadic epilepsy (EP) and autism spectrum disorder (ASD). DeepVariant exhibited higher precision and sensitivity in detecting single nucleotide variants (SNVs), while GATK showed a distinct advantage in identifying rare variants, which are often key to understanding the genetic basis of rare diseases.

Purpose: Pancreatic cancer is one of the most lethal malignancies, with a five-year survival rate rarely exceeding 10%. Due to its asymptomatic onset, it is frequently diagnosed at an advanced and often inoperable stage. This review assesses current strategies for early detection, including genomic testing, advanced imaging technologies, and biomarker-based platforms, with a focus on their clinical utility and integration into surveillance protocols.
