Potential Association between Somatic CAG Repeat Instability in HTT Intermediate Alleles and Clinical Phenotype Research Background Huntington’s disease (HD) is a neurodegenerative disorder caused by the expansion of CAG trinucleotide repeats (≥36 CAG repeats) in the HTT gene. Intermediate alleles (IAs) with 27-35 CAG repeats are generally not cons...

Clinical Impact of Pharmacogenomic Testing on Antiplatelet Therapy Background Pharmacogenomics (PGx) is changing the use of P2Y12 inhibitors (antiplatelet drugs), which are widely used in the treatment of acute coronary syndrome (ACS), neurovascular problems, and vascular diseases. Among them, clopidogrel is a commonly used P2Y12 inhibitor. This pr...

Many Scientists Discover Expansion of Phenotypic Spectrum in Bryant-Li-Bhoj Syndrome Research Background Bryant-Li-Bhoj Syndrome (BLBS) was classified by OMIM in 2022 (OMIM: 619720, 619721), caused by germline variants in the H3.3 (H3F3A and H3F3B) genes. This syndrome is characterized by developmental delay/intellectual disability, craniofacial an...

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 ...
