Summary: This study investigates the association between maternal MTHFR gene polymorphisms and risk of offspring aneuploidy. The results suggest that the MTHFR 677TT genotype and T allele are more prevalent among women with aneuploidy, especially sex chromosome aneuploidies and trisomy 13/18, and among younger women. However, no association is observed between the 1298A>C polymorphism and aneuploidy risk.

Summary: CVST is a severe neurological emergency with variable clinical presentation, onset, risk factors, and outcome. Genetic polymorphisms of the MTHFR gene are associated with CVST, along with other factors such as local infections, general infections, obstetric causes, and head injury. The study found a significant correlation between MTHFR polymorphisms and higher cholesterol levels, low-density lipoprotein cholesterol, and homocysteine levels. High-sensitive C-reactive protein levels and hyperhomocysteinemia were also identified as potential prognostic factors in CVST.

Summary: This study found that MTHFR C677T polymorphism was associated with UF occurrence for the first time, implying that it may increase the risk of forming UF in women of gestational age. Factors such as BMI, gravidity, and parity were not associated with UF size and number, as well as the MTHFR C677T polymorphism, while older maternal age was associated with UF incidence, especially multiple UF.

Summary: Most rare clinical missense variants, including the MTHFR variant impact, cannot be easily classified, as variant effects in MTHFR deficiency depend on environmental factors. The MTHFR atlas scores can differentiate pathogenic from benign variants and correlate with disease onset age in severe MTHFR deficiency. The atlas provides insights on structure-function relationships and the impact of genetic background on missense variations.

Summary: Thymic epithelial tumors (TETs) arise from the epithelial cells of the thymus and account for 1% of all adult malignancies, despite being the most common lesions of the anterior mediastinum. TETs can be classified into different subtypes, including thymomas, thymic carcinomas, and neuroendocrine forms. The challenge lies in the diagnosis and characterization of TETs due to the lack of symptoms and the presence of paraneoplastic disorders. Epigenetic profiling has been explored as a potential tool for tumor characterization and clinical outcomes prediction.

Summary: Different scoring systems have been developed over time for the clinical diagnosis of Beckwith-Wiedemann spectrum (BWSp), with the international consensus score being the most recent. A study was conducted to validate and provide data on the performance metrics of these scoring systems, and their relation to BWSp features, molecular tests, and cancer development probability. The consensus scoring system showed the best performance, while the diagnostic yield of blood-extracted DNA tests was low in patients with a low consensus score. The score did not correlate with cancer development, but certain risks were identified for specific BWSp features.

Summary: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with unknown causes. Epigenetic mechanisms, specifically DNA methylation, may play a role in ASD pathogenesis. This systematic review aimed to investigate the clinical application of DNA methylation in children with ASD, with potential as a biomarker. The results suggest that peripheral DNA methylation could be a promising methodology in ASD research, but further studies are needed to develop clinical applications.

Summary: Exposure to environmental stressors during pregnancy can influence susceptibility to chronic diseases through epigenetic mechanisms. This study used artificial neural networks (ANNs) to explore the links between gestational environmental exposures and DNA methylation in placental and buccal cells. The results showed associations between birth weight and placental H19 methylation, maternal stress during pregnancy and methylation levels of NR3C1 and BDNF in placenta and buccal cells respectively, and air pollutant exposure and maternal MGMT methylation. Associations were also found between placental metal concentrations and methylation levels of OXTR, HSD11B2, MECP2, and MTHFR in different cells. Dioxin concentrations were associated with methylation levels of RELN, HSD11B2, and H19 in placenta and neonatal buccal cells. These findings suggest that environmental stressors during pregnancy can lead to abnormal methylation levels in genes related to embryogenesis and may serve as biomarkers of environmental exposure.

Summary: Neurodevelopmental Disorders (NDs) are a group of heterogeneous diseases with both genetic and environmental factors. Epigenetic dysregulation driven by adverse environmental factors has been found in neurodevelopmental disorders, potentially contributing to their onset. This study focused on analyzing the methylation profile of four well-known neurodevelopment-related genes in mothers of AS, ADHD, and typically developing children, and found significant methylation increases in certain genes in AS mothers compared to ADHD and healthy control mothers. This dysregulation in AS mothers could potentially affect their children's condition and merits further investigation.

Summary: Autism spectrum disorder (ASD) is a challenging neurodevelopmental condition to detect in young females due to the heterogeneity of the behavioral phenotype and the capacity of camouflage. Functional Near-infrared Spectroscopy (fNIRS) is a non-invasive tool that can quantify cortical hemodynamic responses (HDR) and potentially serve as a biomarker for ASD in females. A case-control study on high-functioning preschooler females with ASD demonstrated the feasibility of using visual fNIRS measurements to discriminate between ASD and typical subjects based on signal features such as vHDR amplitude and lateralization. The level of response lateralization was also found to be correlated with the severity of autistic traits, highlighting the importance of sensory symptoms in ASD.

Summary: The central objective of combining discovery science with biomedical applications is to benefit patients and reduce the global disease burden. The conversion of DNA methylation (DNAm) from a biological process to a diagnostic tool is a prime example of this transformation, which took nearly a century. In recent years, DNAm studies have been standardized in clinical applications more than ever before, offering great potential for diagnosing various diseases associated with epigenetic alterations. DNAm detection plays a role in noninvasive prenatal testing and indicates prenatal risk factors in very preterm infants. In the field of cancer, liquid biopsy-based DNAm profiling provides valuable epigenetic biomarkers for early-stage diagnosis.
