Oral Features in Children with X-Linked Hypophosphatemic Rickets: An 8-Year Follow-Up Case Report

Received: 19 March 2024;  Published: 03 April 2025;  doi: 10.21926/obm.genet.2502290

Abstract

X-linked hypophosphatemic rickets (XLHR) is a hereditary metabolic disease caused by the loss of phosphate through the renal tubules into the urine and an associated decrease in serum calcium and potassium phosphate, resulting in bone and dental abnormalities. We report this case, aiming to describe, through an 8-year follow-up case report, the clinical approach adopted in managing dental features in both primary and permanent dentition in a child diagnosed with XLHR. The oral manifestations were mainly premature e [...]

Potential Synergistic Interaction Between Curcumin and Sorafenib Enhances Cytotoxicity in NCI-H5222 Lung Cancer Cells

Received: 25 August 2025;  Published: 15 October 2025;  doi: 10.21926/obm.genet.2504313

Abstract

Non-small cell lung cancer (NSCLC), accounting for approximately 85% of lung cancer cases, remains a leading cause of cancer-related mortality. Genetic alteration such as EGFR mutations, tobacco exposure, and resistance to apoptosis, slows its progression and limits therapeutic success. Although targeted therapies and immunotherapy have improved outcomes for select patients, resistance remains a major challenge, highlighting the need for more effective treatments. This study investigated the potential synergistic i [...]

Differential Expression of MiR-21 and MiR-19 in Biliary Atresia: Diagnostic Potential and Therapeutic Implications

Received: 24 May 2025;  Published: 26 November 2025;  doi: 10.21926/obm.genet.2504319

Abstract

Biliary atresia (BA), a severe pediatric liver disease of unknown etiology, causes neonatal jaundice, progressive cholestasis, and life-threatening liver fibrosis. Emerging evidence suggests microRNAs (miRNAs) – small non-coding RNAs that regulate gene expression by binding target mRNAs may play a role in BA pathogenesis. Circulating miRNAs have shown diagnostic potential for various diseases, prompting our investigation of miR-21 and miR-19 as potential biomarkers in BA. We conducted a case-control study comparing [...]

Network Topology Similarities Across Cancer Types: Identifying Central Protein Hubs for Drug Discovery

Received: 18 June 2025;  Published: 13 October 2025;  doi: 10.21926/obm.genet.2504312

Abstract

A molecular-level understanding of cancer is essential for the development of effective therapies. Constructing protein-protein interaction (PPI) networks offers a valuable approach to identifying dysregulated driver genes and potential therapeutic targets. In this study, we modeled cancer PPI networks as metric spaces and applied mathematical and computational algorithms to analyze their structural and functional properties. Our findings reveal that these networks share a conserved architecture across different ca [...]

DNA-Based Variability of Length Polymorphism of Plant Allergens Coding Genes Homologs in Selected Lamiaceae Herbs

Received: 21 May 2024;  Published: 26 September 2024;  doi: 10.21926/obm.genet.2403263

Abstract

Medicinal plants have been a part of human life from a very early age. In the field of plant genetics, they are still widely investigated for their genomic variability. This study used two DNA marker techniques to obtain polymorphic profiles in selected species from Lamiaceae. Both are based on the variability of plant genes that code for allergens - BBAP (Bet v 1-Based Amplicon Polymorphism) and PBAP (Profilin-Based Amplicon Polymorphism). Variability of Bet v 1 homologues within individual genomes showed similari [...]

Abstract

Diabetes Mellitus (DM) is a degenerative disease that modifies the body’s glucose metabolism. Although glucose is a vital energy source for body cells, individuals with diabetes can either not use insulin efficiently or do not create enough of this hormone, which controls blood sugar. This review aimed to explore the multi-target treatment for diabetes.

A New Database on Constitutional Human Ring Chromosomes

Received: 20 April 2025;  Published: 26 June 2025;  doi: 10.21926/obm.genet.2502298

Abstract

Human ring chromosomes (RCs) constitute one of the rarest described inborn chromosomal rearrangements. At first, they seem to be just another subgroup of structural chromosomal aberrations like translocations, inversions, or insertions. However, RCs are more complex, as they almost always occur in conjunction with a mosaic karyotype constitution, resulting in mosaic monosomy of the affected chromosome. Most likely due to the latter effect, a genotype-phenotype correlation is still not available. To proceed with sol [...]

Received: 30 November 2024;  Published: 04 September 2025;  doi: 10.21926/obm.genet.2503309

Abstract

Biallelic pathogenic variants in C1QBP are an infrequent, yet increasingly recognised, cause of progressive external ophthalmoplegia (PEO). Although most published cases include cardiomyopathy, isolated late‑onset PEO without cardiac disease remains exceptional. To characterise, for the first time, a Moldavian‑Ukrainian pedigree in which homozygous c.612C>G (p.Phe204Leu) in C1QBP causes autosomal‑recessive PEO in the absence of cardiomyopathy, thereby expanding the phenotypic spectrum of C1QBP‑related disease.

Abstract

Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder characterized by early-onset poikiloderma and multisystem abnormalities. Diagnosis is often confirmed through genetic testing, but in many resource-limited settings, molecular studies are unavailable, necessitating reliance on clinical and histopathological evaluation.

Stem Cell-Derived Exosomes: Non-Coding RNA Cargos for Reprogramming the Tumor Immune Microenvironment

Received: 10 October 2025;  Published: 14 January 2026;  doi: 10.21926/obm.genet.2601325

Abstract

Stem cell-derived exosomes (SDEs) have emerged as revolutionary mediators in cancer immunotherapy, offering unprecedented potential to reprogram the immunosuppressive tumor immune microenvironment (TIME). These nano-sized extracellular vesicles, laden with non-coding RNAs (ncRNAs), serve as natural biocompatible carriers, capable of orchestrating immune cell dynamics, stromal remodeling, and tumor cell fate. Unlike their tumor-derived counterparts, which often propagate oncogenic signals, SDEs uniquely harbor immun [...]

Abstract

Leukemia is a heterogeneous group of hematologic malignancies characterized by the dysfunctional proliferation of white blood cells in the bone marrow. Genetic alterations are important risk factors for the development and progression of leukemia, and their detection is crucial. Although many genetic techniques, including karyotyping, fluorescence in situ hybridization (FISH), and polymerase chain reaction (PCR), have provided valuable information, they all have the limitation of incomplete genomic coverage.

Received: 29 September 2025;  Published: 08 January 2026;  doi: 10.21926/obm.genet.2601323

Abstract

Tuberous sclerosis (TS) is one of the most common hereditary tumor syndromes, occurring with an average incidence of 1 in 9,000 newborns worldwide. The disease manifests itself through the development of tumors of the brain, kidneys, heart, lungs, and skin, along with characteristic depigmented spots. Tuberous sclerosis is caused by germline variants in the TSC1 (encoding hamartin) and TSC2 (encoding tuberin) genes. The hamartin-tuberin protein complex, together with the TBC1D7 molecule, inhibits the serine/threoni [...]

Abstract

Advances in antiretroviral therapy (ART) have normalized the life expectancy of people living with HIV (PLWH) but have been linked to a premature presentation of age-related comorbidities, including cancer. Telomere length (TL) is a marker of cellular aging and was investigated in blood leukocytes from 78 PLWH on ART, compared with 163 HIV-uninfected controls. The PLWH group was stratified into three subgroups: HIV-only (n = 57), HIV with AIDS-defining cancer (ADC, n = 9), and HIV with NADC (n = 12). Quantitative p [...]

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.
