OBJECTIVE:
To explore the genetic etiology of 46 Chinese pedigrees affected with Hereditary multiple exostoses (HME) and provide genetic counseling and reproductive intervention.
METHODS:
Whole-exome sequencing and Sanger sequencing were carried out on 87 patients from the 46 pedigrees to analyze the variants of EXT1 and EXT2 genes. Pathogenicity of the variants was assessed based on the guidelines from the American College of Medical Genetics and Genomics and Association for Molecular Pathology (ACMG/AMP). Prenatal diagnosis and preimplantation genetic testing (PGT) were provided for couples with identified pathogenic mutations. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: LL-SC-SG-2014-010).
RESULTS:
In total 17 and 22 pathogenic variants were respectively identified in the EXT1 and EXT2 genes, among which 5 EXT1 and 12 EXT2 variants were unreported previously. Three patients with no family history were found to harbor de novo variants of the EXT1 gene. Twenty nine couples had opted for PGT or underwent prenatal diagnosis following natural conception, and 17 healthy babies were born.
CONCLUSION
This study has clarified the genetic etiology of 45 HME pedigrees and identified 17 novel variants, which has enriched the mutational spectrum of the EXT1 and EXT2 genes. Reproductive intervention through PGT and prenatal diagnosis have prevented the recurrence of HME in these families.

OBJECTIVE:
To explore the clinical phenotype, pregnancy outcome and follow-up of fetuses with 15q11.2BP1-BP2 microdeletions in order to provide a basis for prenatal and reproductive consultation.
METHODS:
From March 2019 to December 2023, 20 fetuses who were diagnosed with 15q11.2BP1-BP2 microdeletion syndrome at the Prenatal Diagnosis Center of General Hospital of Ningxia Medical University were selected as the study subjects. Results of genetic testing and ultrasound examination, outcome of pregnancy, and postnatal follow-up were retrospectively analyzed. This study has been approved by the Ethics Committee of General Hospital of Ningxia Medical University ([2020]0520B).
RESULTS:
None of the 20 fetuses was found to have chromosomal abnormality, whilst all were found to harbor a 15q11.2 BP1-BP2 microdeletion by low-depth whole genome sequencing (CNV-seq). The range of deletions was determined as 0.26 ~ 0.87 Mb, and all were rated as pathogenic CNVs. Three fetuses had abnormal ultrasound findings, including 1 with widened renal pelvis, 1 with agenesis of corpus callosum, and 1 with nuchal fold thickening. Parental verification in 10 couples verified that two fetal deletions were de novo, whilst the remaining eight were inherited from a phenotypically normal parent. Following genetic counseling, three couples had opted to terminate the pregnancy, whilst the remaining 17 had continued with the pregnancy until delivery. The 17 liveborns were followed up for 2 months to 5 years, with no obvious abnormality in growth and development noted.
CONCLUSION
CNV-seq plays an important role in the prenatal diagnosis of 15q11.2 BP1-BP2 microdeletions. Such deletions may not always lead to disease phenotypes. Individualized consultation and long-term follow-up, in combination with intrauterine ultrasound and parental verification are necessary.

OBJECTIVE:
To assess the value of combined detection strategies using multiple technologies for the genetic testing and prenatal diagnosis for pedigrees affected with Duchenne muscular dystrophy (DMD) for optimizing genetic counseling and reproductive guidance.
METHODS:
This study has involved 142 subjects from 65 suspected DMD families who had visited the First Affiliated Hospital of Chongqing Medical University from January 2018 to December 2023. A combination of multiple ligation-dependent probe amplification (MLPA), quantitative fluorescence PCR, and next-generation sequencing (NGS) was used. After confirming the genetic diagnosis of the probands, prenatal diagnosis was provided for carrier mothers. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: 2021-264).
RESULTS:
Among the 142 subjects tested, 73 cases of large deletions/duplications and 15 cases of small variants of the DMD gene were detected. The hotspot regions for the variants were exons 45 to 55. A total of 41 variant types were identified, of which 3 were previously unreported. In 19 families with suspected patients, 7 exonic deletions, 2 exonic duplications, and 3 small variants were identified. Prenatal diagnosis was performed on 48 fetuses from 46 families, revealing 16 affected male fetuses (including 12 with deletion variants, 2 with duplication variants, and 2 with small variants). Seven carrier females were identified among the 16 female fetuses (including 6 with deletions and 1 with duplication). Among the couples with an affected fetus, 16 had opted to terminate the pregnancy, while the parents of 32 fetuses had chosen to continue with the pregnancy. In families undergoing prenatal diagnosis, 53 (79.1%) pregnant women and their family members were found to carry mutations of the DMD gene.
CONCLUSION
The combined detection strategy of MLPA, qPCR, and NGS can encompass large deletions/duplications and small variants of the DMD gene, providing timely and accurate prenatal diagnosis for families affected by DMD. In conjunction with genetic counseling, this can effectively reduce the risk of producing affected offspring, which is crucial for the prevention and control of this disease.

OBJECTIVE:
To evaluate the clinical significance of a hemizygous c.1042-10G>C variant of the SLC9A7 gene NM_001257291.2) previously identified in individuals with neurodevelopmental disorders, and to provide an evidence-based guidance for prenatal genetic counseling.
METHODS:
Four families presented at the Medical Genetics Center of Henan Provincial People's Hospital between December 2022 and July 2024 were included in this study. Phenotypic information and biological samples were collected from family members. Genomic DNA was extracted and subjected to whole-exome sequencing and copy number variation analysis to identify candidate pathogenic variants. Sanger sequencing was performed for familial co-segregation analysis. Reverse-transcription PCR was used to assess the RNA splicing pattern of the variant in peripheral blood samples. Quantitative PCR was employed to analyze the expression profiles of various SLC9A7 transcripts in fetal brain tissue and peripheral blood samples. Pathogenicity of the variant was classified based on guidelines from the American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of Henan Provincial People's Hospital (Ethics No.: 2021-171).
RESULTS:
Six hemizygous males carrying the SLC9A7 c.1042-10G>C variant were identified among the four families, which included three adult males and two male infants with normal phenotypes. Only one affected male from family 3 exhibited global developmental delay, short neck, webbed neck, ocular dysplasia, and congenital corneal leukoma. He also had a history of perinatal asphyxia and carried an additional hemizygous variant HUWE1 c.12283C>G. Reverse-transcription PCR showed no aberrant splicing in heterozygous or hemizygous carriers compared to healthy controls, suggesting that the variant does not affect RNA splicing. Quantitative PCR revealed that NM_001257291.2 is the predominant transcript expressed in fetal brain tissue and peripheral blood.
CONCLUSION
The SLC9A7 c.1042-10G>C variant does not alter RNA splicing and is present in multiple phenotypically normal males, which supported its classification as a benign variant.

OBJECTIVES
This study described the demographic and clinical profile, mental health problems, prevalence of psychiatric conditions, psychosocial interventions used, and outcomes of the management of mental health problems among in-patients admitted to non-psychiatry units of tertiary hospitals referred to mental health care providers; and described gender-disaggregated data related to mental health care providers and patients receiving psychosocial interventions in tertiary hospitals.
METHODSThis study employed a mixed-method design, using both qualitative and quantitative methodologies following the convergence model of triangulation. The following were the data sources: (1) cross-sectional review of charts of patients referred for psychosocial problems using the ICD-10 classification; (2) a survey of mental health service providers; (3) key informant interviews of mental health service providers; and (4) focus group discussions of mental health providers. All data were collated, compared, and contrasted, then analyzed using the convergence model of triangulation design.
RESULTSAmong the 3,502 patients in the chart review, 1,870 (53.40%) were males. The median age was 46.08 years and 92.06% were adults. The most common diagnosis among the patients were mood disorder (744, 21.25%) and organic mental disorder (710, 20.27%). Combination treatment of psychosocial intervention and pharmacology was the most common strategy received by patients. There was a higher proportion of patients admitted to public hospitals (996, 45.27%) who received psychosocial interventions only compared to those admitted to private hospitals (235, 18.05%). There were 3,453 out of 3,502 in-patients referred for psychiatric intervention. Of these 2,420 (70%) received psychoeducation, 2,365 (68.5%), received supportive psychotherapy/counseling, 535 (15.5%) family therapy, and 286 (8.3%) behavior modification. There were more patients given psychosocial interventions 2,541 (72.56%) who were discharged with instruction to follow-up, while around one in 10 (456, 13.02%) was not instructed to do a follow-up consultation. The types of interventions across all data sources were similar.
CONCLUSIONThe most common type of management for psychosocial problems of in-patients in tertiary hospitals was a combination of psychosocial intervention and pharmacotherapy. Psychoeducation, supportive psychotherapy/ counseling, and family therapy were the most often given psychosocial interventions. The patient-related reasons for the choice of interventions were patient’s medical status (diagnosis and severity of symptoms) and psychological status (psychological mindedness), while the provider-related factors influencing the choice of intervention were provider’s skills and personal preference. Moreover, resources (human and material) and service provision policies (treatment guidelines and aftercare interventions) were the most common hospital-related factors. Further prospective research to determine the associated patients, providers, and hospital factors in larger geographic and cultural settings will provide evidence for the effectiveness and outcomes of psychosocial interventions.

Objective:By conducting genetic testing of hereditary hearing loss in pregnant women within 17 weeks of gestation in Dali areas, the importance of genetic testing and genetic counseling during pregnancy was emphasized. Methods:Twenty-one mutation sites of 4 hearing loss genes, including GJB2, GJB3, SLC26A4 and mtDNA, were detected by PCR amplification technology. The positive ratio, mutation ratio and ethnic distribution of positive samples were statistically described. Results:The positive ratios of GJB2 and SLC26A4 genes were 1.24% and 1.43%, respectively, with mutation rates of 40.62% and 46.88% in the positive samples, respectively. The positive ratio of GJB3gene was 0.19%, and mtDNA mutation genes accounted for 0.14%, and all of them were mtDNA(Heterozygous). There was only one case of GJB2/SLC26A4 double positive multi-gene mutation, with a positive ratio of 0.05%. The frequency of GJB2 c. 235delC site was the highest, accounting for 65.38% of GJB2 mutation genes and 26.56% of mutation gene samples. Conclusion:GJB2 and SLC26A4 are the most common genes of hearing loss, and GJB2 c. 235delC site is the most common mutation site. Identifying the hearing loss mutation site is of great importance to prevent the birth of hereditary hearing loss children, and genetic diagnosis, genetic counseling, and appropriate intervention are crucial to alleviate congenital problems.

Complementary and integrative healthcare (CIH) is increasingly recognized as a valuable approach to empowering and activating cancer patients. Studies have shown that higher patient activation is positively associated with improved health outcomes and reduced healthcare costs. The CCC-Integrativ study aimed to assess the implementation of an evidence-based counseling service on CIH at four Comprehensive Cancer Centers (CCC) in Germany. In this controlled implementation study, the patient-level intervention included three CIH consultations within a 3-month period delivered by interprofessional teams of physicians and nurses. The primary endpoint was patient activation using the PAM-13 at baseline (T1) and post-intervention (T2), and compared between control (CO, receiving routine care) and the intervention group (IG) using an analysis of covariance. Missing data were handled with multiple imputations. Maintenance effects at 6-month follow-up (T3) were investigated using a linear mixed model. A total of n = 1128 oncology patients (CO = 443, IG = 685) with diverse tumor entities and cancer stages were included in the study. The overall mean baseline PAM-13 score was 69.74 (SD = 14.24) (n = 959 (85.0%)). A statistically significant between-group difference in post-intervention PAM-13 scores was observed (Fgroup(1, 1866.82) = 8.634, P = 0.003), with an adjusted mean difference of 2.22 PAM-points. Age, gender, tumor entity, disease stage, or CCC study site did not significantly predict post-treatment PAM-13 scores. The maintenance effect of the intervention was not statistically significant (FtimeXgroup(1, 3316.04) = 2.337, P = 0.096). Individually tailored counseling on CIH, offered by specifically trained, interprofessional teams, significantly improved patient activation. Given the established positive effects of higher patient activation, the implementation of such a program at cancer centers may yield beneficial outcomes for both patients and the healthcare system.
