Congenital factor VII (FVII) deficiency is the most common rare bleeding disorder (RBD), presenting with various clinical manifestations. Given the heightened risk of life-threatening bleeding and fatal hemorrhagic complications, prompt detection of the disorder is critical, especially in cases with low FVII levels and a history of familial severe clinical presentations. In such cases, prenatal diagnosis (PND) emerges as a life-saving option. In this study, we reported two PNDs in a family with a positive family hi [...]

Hereditary Cardiomyopathies (HCs) are defined as genetically determined cardiovascular diseases (CVDs) that frequently exhibit a familial inheritance pattern. These conditions include cardiomyopathies (CMs), arrhythmias (ARs), and other inherited cardiovascular syndromes. In Panama, the national incidence of Hereditary Cardiomyopathies remains unknown. The objective was to identify genetic variants in Panamanian patients diagnosed with HCs or cardiac arrhythmias and subsequently to identify carrier families to prov [...]

Isolated duplications of the long arm of chromosome 3 (3q) are rare chromosomal abnormalities. To date, approximately 32 pure cases have been documented. Most reported 3q duplications arise from unbalanced translocations or inversion-loops mechanisms and are associated with additional chromosomal imbalances, making pure duplications particularly valuable for genotype-phenotype correlations. We report a 17-year-old female with a de novo pure tandem duplication of 3q26.33-q28 (~10.945 Mb). The clinical course was mar [...]

Acute myeloid leukemia (AML) is a heterogeneous hematologic malignancy with genetic and clinical characteristics. Recent advances in multi-omic technologies, including genomics, epigenomics, transcriptomics, proteomics, metabolomics, immunomics, microbiome profiling, and both spatial and single-cell analyses, have greatly enhanced our understanding of AML pathobiology. Substantial multi-omic studies show that recurrent driver mutations not only impart traditional genomic lesions but also participate in chromatin re [...]

Cancer remains one of the major global challenges due to its complex and heterogeneous molecular nature across individuals. Recent advances in technology have enhanced the understanding of cancer’s molecular mechanisms, paving the way for the development of effective therapeutics. These include small-molecule inhibitors and monoclonal antibodies, used to interfere with the oncogenic signaling pathways. Immunotherapy has also emerged as a promising area in cancer therapy, with approaches such as immune checkpoint in [...]

Noonan syndrome (NS) is an autosomal dominant disorder with a wide spectrum of symptoms and clinical phenotypes, including short stature, congenital heart defects (CHD), and distinctive facial features. A pathogenic variant in the PTPN11 gene is the major cause of NS. This is a preliminary study in Indonesia involving 29 patients with clinical features of NS. Detailed clinical and echocardiography data were collected. Genomic DNA was extracted from a peripheral blood sample. Exome sequencing or PCR followed by Sang [...]

Changes in the environment driven by climate change are becoming significant stressors that impact brain function, but the connections between these changes and neural plasticity remain unclear. This review aims to offer a comprehensive synthesis of the impact of climate-related stressors on neural plasticity via genetic and epigenetic mechanisms. A structured literature search (2000-2025) was conducted using PubMed, Scopus, and Web of Science, integrating evidence from in vitro, animal, and human studies. Findings [...]

Sensorineural hearing loss (SNHL) describes a diverse group of clinically and genetically distinct disorders of the auditory system. SNHL is associated with mutations in up to 150 genes. Among them is Cadherin 23 (CDH23), which is associated with both Usher syndrome and non-syndromic hearing loss. In the current study, we used WES to find the genetic cause of SNHL in an extended Iranian family. WES and subsequent Sanger sequencing confirmed the occurrence of a novel homozygote variant in the CDH23 gene (c.817T>C, p [...]

Craniosynostosis is a disorder characterized by premature closure of cranial sutures, resulting in restricted skull growth perpendicular to the affected suture and compensatory growth in other directions. Over 180 syndromes have been classified under craniosynostosis, of which eight are associated with mutations in the fibroblast growth factor receptor 2 (FGFR2) gene: isolated coronal synostosis, Pfeiffer syndrome, Crouzon syndrome, Apert syndrome, Beare–Stevens syndrome, Jackson–Weiss syndrome, Crouzon syndrome wi [...]
