Expanded Phenotypic Spectrum of Neurodevelopmental and Neurodegenerative Disorder Bryant-Li-Bhoj Syndrome with 38 Additional Individuals

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...

Upstream Open Reading Frame-Introducing Variants in Patients with Primary Familial Brain Calcification

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...

Utilizing a Yeast Genetic Model to Validate the Pathogenicity of ACTA2 Variants Associated with Aortic Aneurysms

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...

Widespread Exclusive Yin Yang Haplotypes in the Human Genome

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, HLA and Polygenic Risk Score Analyses for Prevalent and Persistent Cervical Human Papillomavirus (HPV) Infections

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...

Further Evidence Supporting the Role of GTDC1 in Glycine Metabolism and Neurodevelopmental Disorders

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 Profiling in Kabuki Syndrome: Reclassification of Germline KMT2D VUS and Sensitivity in Validating Postzygotic Mosaicism

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...
