Chinese Journal of Medical Genetics 2026;43(4):295-300
OBJECTIVE:
To investigate the clinical manifestations and genetic etiology of a fetus with Neurodevelopmental disorders with deformed facial features and distal skeletal abnormalities (NEDDFSA).
METHODS:
Clinical data of a NEDDFSA fetus diagnosed at the Affiliated Women and Children's Hospital Affiliated to Ningbo University in March 2025 was selected as the study subject. Whole-exome sequencing (WES) was carried out on the amniotic fluid and parental peripheral blood samples, and candidate variants was verified by Sanger sequencing. The pathogenicity of candidate variant was rated based on guidelines from the American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: EC2023-094).
RESULTS:
At 30 weeks of gestation, the fetus was found to have microcephaly, short femur and intrauterine growth restriction. WES revealed that the fetus harbored a de novo heterozygous frameshift variant c.2633dup (p.Gly879ArgfsTer22) of the ZMIZ1 gene, which was rated as pathogenic (PM2_Supporting+PS2_Supporting+PVS1). Combined with 25 cases from the literature, the main manifestations of patients have included intellectual disability, growth retardation and cranio-limb skeletal dysplasia, albeit without clear genotype-phenotype correlation.
CONCLUSION
The de novo variant c.2633dup (p.Gly879ArgfsTer22) of the ZMIZ1 gene probably underlay the NEDDFSA in this fetus. Genetic testing has enabled accurate prenatal diagnosis and provided evidence for genetic counseling and reproductive guidance of this family.

Journal of Medicine University of Santo Tomas 2026;10(1):1873-1882
This study explores the impact of perceived stress on the academic performance of orthopaedic surgery residents in the Philippines. Conducted as a cross-sectional investigation, it involved 126 residents who participated in the 2024 Philippine Board of Orthopaedics In-Service Training Examination (ITE). Stress levels were assessed using the Perceived Stress Scale-10 (PSS-10), while ITE scores served as the measure of academic performance. A significant negative correlation was identified between stress and academic performance (r = -0.3138, p = 0.00010). Residents experiencing high stress achieved lower scores (55.2%) compared to those with low to moderate stress (61.8%). Other demographic variables such as sex, age, marital status and type of training institution (public and private) were not significantly associated with stress level findings. On the other hand, key factors contributing to elevated stress included insufficient sleep (0–4 hours nightly; OR = 5.83, p = 0.0289) and limited awareness of mental health issues (OR = 13.34, p = 0.0014). These results highlight the pressing need for stress reduction initiatives, improved mental health education and strategies to address challenges posed by sleep deprivation and extensive work hours. This study provides a foundation for improving both academic outcomes and overall well-being in residency programs.

OBJECTIVE:
To explore the clinical phenotype and genetic characteristics of a child with neurodevelopmental disorder caused by homozygous frameshift variant of the TRAPPC6B gene, and to provide reference for the diagnosis of the disease.
METHODS:
A child with neurodevelopmental disorder caused by homozygous variant of TRAPPC6B gene who was admitted to the Children's Hospital Affiliated to Zhengzhou University in March 2023 due to "inability to stand and walk independently at 1 year and 3 months old" was selected as the study object. The clinical data were collected by retrospective analysis method. Target region high-throughput sequencing was carried out on the child and parental peripheral blood samples, and candidate variant was verified by Sanger sequencing and bioinformatic analysis. The pathogenicity of variant was rated according to the Standards and Guidelines for the Interpretation of Sequence Variants released by American College of Medical Genetics and Genomics (ACMG) (hereinafter referred to as ACMG guidelines). The study has been approved by the Medical Ethics Committee of the Children's Hospital Affiliated to Zhengzhou University (Ethic No.2022-K-L025).
RESULTS:
The child was a 1-year-and-3-months-old boy whose parents were sib mating. The child presented with global developmental delay, microcephaly and short stature. MRI showed poor white matter myelination, abnormal signals of bilateral periventricular white matter and bilateral external sac, thin corpus callosum, and widening of the third ventricle. Genetic testing revealed that the TRAPPC6B gene of the child had a homozygous variant of c.240_241delAA (p.Q80Hfs*34), which was inherited from his parents. According to the ACMG guidelines, this variant was judged to be potentially pathogenic (PVS1_Strong+PM2_Supporting+PM3_Supporting), resulting in premature occurrence of terminator codons and a change in the three-dimensional structure of protein. The variant was located in the functional domain, which may directly affect the functional domain of the protein, resulting in functional domain defects.
CONCLUSION
The frameshift variation of TRAPPC6B gene c.240_241delAA (p.Q80Hfs*34) has not been reported, which may be the genetic cause of neurodevelopmental disorders in child in this study. These findings expand the variation spectrum of TRAPPC6B gene and provide basis for genetic counseling and prenatal diagnosis of this family.

OBJECTIVE:
To investigate the clinical and genetic characteristics of a Chinese pedigree affected with Neurodevelopmental disorder with absent language and variable seizures (NEDALVS) due to variant of WASF1 gene, and to review the literature on NEDALVS associated with WASF1 gene variants.
METHODS:
A 4-year-and-8-month-old boy with NEDALVS diagnosed at Linyi People's Hospital in July 2024 due to "discovering language development delay for more than 2 years" and his family members were selected as the study subjects. Clinical data of the family members were collected. Peripheral venous blood samples were collected from family members. Whole-exome sequencing (WES) was performed, and candidate variants were verified, by Sanger sequencing. Pathogenicity of candidate variant was classified according to the Standards and Guidelines for the Interpretation of Sequence Variants established by the American College of Medical Genetics and Genomics (ACMG). Using the MUpro website, SWISS-MODEL, PyMOL, Clustal X, PolyPhen-2, and Mutation Taster software, bioinformatics analysis of protein three-dimensional structure modeling for gene mutations, cross-species conservation of mutant amino acids, and pathogenicity prediction of mutation sites. Relevant literature was retrieved from databases such as CNKI, Wanfang Data Knowledge Service Platform, and PubMed, and the clinical phenotypes and genotypes of patients with WASF1 gene mutations reported in the literature were summarized and analyzed. This study was approved by the Medical Ethics Committee of Linyi People's Hospital (Ethics No.: YX200303).
RESULTS:
The proband, a 4-year and 8-month-old male, mainly presented with delayed language and motor development, accompanied by autistic behaviors; the proband's younger brother was 2 years and 7 months old at the time of consultation, mainly presented with delayed language and motor development, accompanied by short stature; the proband's mother mainly presents with limited language expression and poor interpersonal interaction; the proband's maternal grandmother mainly presents with soliloquizing?behavior. The results of WES showed that the proband carried a heterozygous mutation c.214C>T (p.Arg72Cys) in the WASF1 gene, and this site has not been recorded in the database. Sanger sequencing confirmed that the proband's younger brother, mother, and maternal grandmother had harbored the same variant. Based on the guidelines from the ACMG, this variant was rated as likely pathogenic (PM2_Supporting+PP1+PP3+PP4). Through SWISS-MODEL homology modeling and PyMOL structure visualization analysis, it was further confirmed that this variant can lead to a decrease in protein stability. Amino acid sequence conservation analysis of the WASF1 protein using Clustal X software suggested that the c.214C>T (p.Arg72Cys) variant has caused replacement of a highly conserved amino acid. According to the results of PolyPhen-2 and Mutation Taster, the p.Arg72Cys variant was predicted to be a hazardous. By following the retrieval strategy set in this study, a total of 5 research articles regarding to patients with NEDALVS caused by WASF1 gene mutations were retrieved, which involved 15 patients. Combining the proband and their family members discovered in this study, there were a total of 19 NEDALVS patients. The main clinical features included: motor developmental delay (100%, 17/17), language/intellectual developmental delay (100%, 17/17), epilepsy (64.7%, 11/17), autistic behavior (76.5%, 13/17), hypotonia (70.6%, 12/17), abnormal electroencephalogram (64.7%, 11/17), and short stature (17.6%, 3/17). All 19 patients had heterozygous mutations, with 8 mutation sites. Missense mutations were the most common, accounting for 84.2% (16/19).
CONCLUSION
A pathogenic variant of the WASF1 gene was identified in a pedigree affected with NEDALVS. Discovery of the novel variant has, expanded the mutational spectrum of the WASF1 gene.

Aims or objective: To determine the prevalence of neurodevelopmental disorder (NDD) comorbidities and their association with the clinical profile of children with focal epilepsy treated at the Philippine Children’s Medical Center from 2023 to 2024.
Materials and Method: This cross-sectional analytical study was conducted from June 10, 2023 to June 1, 2024 at the Philippine Children's Medical Center. Detailed information was obtained for each case according to protocol. A complete history was taken from the accompanying caretakers. Children aged 0 to 7 years and 11 months, recently diagnosed with focal epilepsy, were evaluated using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5-TR) criteria. The level of early child development was determined based on the total Battelle Developmental Inventory-2 developmental quotient score.
Results: The study examined 246 children with focal epilepsy. Significant findings included those children with NDD had a higher median age (4.67 years) compared to those without NDD (3.37 years) (p < .001). A higher proportion of non-NDD children were under one year old. Children without NDD had mothers with higher educational attainment (p = .015) and came from families with higher incomes (p = .003). Neonatal complications such as hypoxic-ischemic encephalopathy (HIE) and sepsis were more common in children with NDD (p = .005 and p = .006). Phenobarbital use was more frequent in children with NDD (p = .001), who also had more abnormal EEG and neuroimaging findings (p < .001). Neurodevelopmental evaluations were conducted later for children with NDD (p < .001). A significant number (75.20%) of children exhibited neurodevelopmental problems, with global developmental delay being most prevalent. Crude analysis showed associations between age, number of antiseizure medications, and delays in evaluation with increased odds of NDD.
Conclusion: The study offers insights into children with focal epilepsy at a tertiary hospital in the Philippines, emphasizing the impact of low socioeconomic status, age, birth complications and multiple anti-seizure medications. These findings are vital for clinicians to modify care plans through a multidisciplinary approach to enhance outcomes and improve quality of life in this high-risk population.

Neuropsychiatric disorders arise from complex interactions between genetic and environmental factors. DNA methylation, a reversible and environmentally responsive epigenetic regulatory mechanism, serves as a crucial bridge linking environmental exposure, gene expression regulation, and neurobehavioral outcomes. During long-duration deep-space missions, astronauts face multiple stressors-including microgravity, cosmic radiation, circadian rhythm disruption, and social isolation, which can induce alterations in DNA methylation and increase the risk of neuropsychiatric disorders. Genome-wide DNA methylation research can be divided into 3 major methodological stages: Study design, sample preparation and detection, and data analysis, each of which can be applied to astronaut neuropsychiatric health monitoring. Systematic comparison of the Illumina MethylationEPIC array and whole-genome bisulfite sequencing reveals their complementary strengths in terms of genomic coverage, resolution, cost, and application scenarios: the array method is cost-effective and suitable for large-scale population studies and longitudinal monitoring, whereas sequencing provides higher resolution and coverage and is more suitable for constructing detailed methylation maps and characterizing individual variation. Furthermore, emerging technologies such as single-cell methylation sequencing, nanopore long-read sequencing, and machine-learning-based multi-omics integration are expected to greatly enhance the precision and interpretability of epigenetic studies. These methodological advances provide key support for establishing DNA-methylation-based monitoring systems for neuropsychiatric risk in astronauts and lay an epigenetic foundation for safeguarding neuropsychiatric health during future long-term deep-space missions.

Neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and intellectual developmental disorder (IDD), are highly prevalent and lack effective treatments, posing significant health challenges. These disorders are frequently comorbid with disruptions in sleep rhythms, and sleep-related indicators are often used to assess disease severity and treatment efficacy. Recent evidence has highlighted the crucial roles of circadian rhythm disturbances and circadian clock gene mutations in the pathogenesis of NDDs. This review focuses on the mechanisms by which circadian rhythm disruptions and circadian clock gene mutations contribute to cognitive, behavioral, and emotional disorders associated with NDDs, particularly through the dysregulation of dopamine system. Additionally, we discussed the potential of targeting the circadian system as novel therapeutic strategies for the treatment of NDDs.

INTRODUCTION:
The coronavirus disease 2019 (COVID-19) pandemic has caused significant mental distress in populations globally. At the frontline of the pandemic, emergency departments (EDs) are the prime setting to observe the effects of the pandemic on the mental health of the population. We aimed to describe the trend of mental health-related ED attendances at an acute hospital in Singapore before and during the various stages of the COVID-19 pandemic.
METHODS:
This is a retrospective, descriptive study of patients who presented to the ED between 1 January 2019 and 31 December 2020. Patients diagnosed with mental health-related systematised nomenclature of medicine who visited the ED during this period were identified and were placed into mental health diagnosis categories for analysis. A comparison was made between patients who presented before the pandemic (2019) and during the pandemic (2020).
RESULTS:
During the study periods, we identified 1,421 patients, of whom 27 were excluded due to non-mental health-related diagnoses, leaving 1,394 patients for analysis. There was a 36.7% increase in mental health-related ED presentations from 2019 to 2020. The proportion of higher-acuity mental health-related ED attendances and number of suicide attempts also increased.
CONCLUSION
Our study described an increase in the proportion of high-acuity mental health-related ED attendances during the COVID-19 pandemic. Emergency physicians must be cognisant of the effects of the pandemic on mental health. Further research should be conducted to better equip the healthcare system for handling all aspects of the pandemic.

Based on serum metabolomics and gut microbiota technology, this study explores the effects and mechanisms of the water extract of Ziziphi Spinosae Semen(SZRW) and the petroleum ether extract of Ziziphi Spinosae Semen(SZRO) in improving depressive-like behaviors induced by sleep deprivation. A modified multi-platform water environment method was employed to establish a rat model of sleep deprivation. Depressive-like behaviors in rats were assessed through the sucrose preference test and forced swim test. The expression of barrier proteins, such as Occludin, in the colon was determined by immunofluorescence. UPLC-Q-Orbitrap MS was utilized to analyze the serum metabolic profiles of sleep-deprived rats, screen for differential metabolites, and analyze metabolic pathways. The diversity of the gut microbiota was detected using 16S rRNA gene sequencing. Spearman correlation coefficient analysis was conducted to assess the correlation between differential metabolites and gut microbiota. The results indicated that SZRO significantly increased the sucrose preference index and decreased the immobility time in the forced swim test in rats. A total of 34 differential metabolites were identified through serum metabolomics. SZRW and SZRO shared five metabolic pathways, including phenylalanine metabolism. SZRW uniquely featured taurine and hypotaurine metabolism, while SZRO uniquely featured linoleic acid metabolism and tyrosine metabolism. Correlation analysis revealed that SZRW could upregulate the abundance of Bilophila, promoting the production of indole-3-propionic acid and subsequently upregulating the expression levels of intestinal tight junction proteins such as ZO-1, Occludin, and Claudin-1. SZRO could indirectly influence metabolic pathways such as arginine metabolism and linoleic acid metabolism by upregulating the abundance of gut microbiota such as Coprococcus and Eubacterium species. Both SZRW and SZRO can regulate endogenous metabolism, including amino acids, energy, and lipids, alter the gut microbiota microecology, and improve depressive-like behaviors. SZRO demonstrated superior effects in regulating metabolic pathways and gut microbiota structure compared to SZRW. The findings of this study provide a scientific basis for elucidating the pharmacodynamic material basis of Ziziphi Spinosae Semen.

Cardiovascular diseases and psychological disorders represent two major threats to human physical and mental health. Research on electrocardiogram (ECG) signals offers valuable opportunities to address these issues. However, existing methods are constrained by limitations in understanding ECG features and transferring knowledge across tasks. To address these challenges, this study developed a multi-resolution feature encoding network based on residual networks, which effectively extracted local morphological features and global rhythm features of ECG signals, thereby enhancing feature representation. Furthermore, a model compression-based continual learning method was proposed, enabling the structured transfer of knowledge from simpler tasks to more complex ones, resulting in improved performance in downstream tasks. The multi-resolution learning model demonstrated superior or comparable performance to state-of-the-art algorithms across five datasets, including tasks such as ECG QRS complex detection, arrhythmia classification, and emotion classification. The continual learning method achieved significant improvements over conventional training approaches in cross-domain, cross-task, and incremental data scenarios. These results highlight the potential of the proposed method for effective cross-task knowledge transfer in ECG analysis and offer a new perspective for multi-task learning using ECG signals.
