Research Background and Problem Statement Primary Familial Brain Calcification (PFBC) is a rare neurological disorder characterized by microvascular calcification in the basal ganglia and other brain regions. Although at least six genes associated with PFBC have been identified (including SLC20A2, XPR1, PDGFB, PDGFRB, MYORG, and JAM2), the pathogen...

Pathological Study of a New ACTA2 Mutation Causing Aortic Aneurysm: Validation Using a Yeast Model Research Background Thoracic aortic aneurysm and dissection (TAAD) is a potentially fatal vascular disease with mechanisms that are still not fully understood. The ACTA2 gene encodes α-smooth muscle actin, a key component of the vascular smooth muscle...

Unique Yin Yang Haplotypes Widely Present in the Human Genome Research Background In genomic studies, yin yang haplotypes refer to pairs of haplotypes that differ at every site. While previous independent reports have indicated the existence of unique yin yang haplotypes, no systematic search had been conducted. Therefore, to better understand the ...

Genome-wide and Polygenic Risk Score Analysis of High-Risk Human Papillomavirus (hrHPV) Infection in the Cervix Background Cervical high-risk human papillomavirus (hrHPV) infection is the second largest carcinogenic infection globally, accounting for approximately 31.4% of all infection-related cancers (about 690,000 cases out of 2.2 million cancer...

In recent years, research on Neurodevelopmental Disorders (NDDs) has uncovered numerous genetic variants associated with NDDs, ranging from Single Nucleotide Variants (SNVs) to large structural changes (such as chromosomal rearrangements). Against this research background, Edoardo Errichiello, Mauro Lecca, Chiara Vantaggiato, and other researchers ...

DNA methylation analysis in Kabuki syndrome: reclassification of germline KMT2D variants Background Kabuki syndrome (KS) is a rare multiple congenital anomaly/neurodevelopmental disorder caused by heterozygous inactivating variants or structural rearrangements in the KMT2D gene. Although KS is recognizable due to its distinctive facial features, di...

Feasibility Study of Opportunistic Genomic Screening in Pediatric Cancer Patients and Its Family Acceptance Research Background With the development and application of genomic medicine, the care for patients with severe diseases is gradually being optimized. Especially in the field of childhood cancer, whole-genome series DNA testing has become an ...

Discovery of the Recessive Effect of Human Polymerase δ Proofreading Deficiency: Through Mutation Analysis of Normal Cells and Cancer Cells with POLD1 Mutations Background Introduction The disruption of DNA repair is one of the main mechanisms leading to hereditary cancer. Heterozygous pathogenic variants in the exonic regions of POLD1 and POLE aff...

Framework for Evaluation and Reporting of Incidental Findings in Clinical Genome Sequencing Research Background In current clinical practice, clinical genome sequencing (CGS) is gradually becoming an important means for diagnosing rare genetic diseases. However, incidental findings (IFs) are often encountered in genome sequencing, which are unexpec...

Adaptive Robust Method for Multi-trait Genome-wide Association Studies Abstract: Genome-wide association studies (GWAS) over the past decade have identified thousands of genetic variants associated with human traits or diseases. However, the heritability of many traits remains largely unexplained. Traditional single-trait analysis methods are overl...
