OBJECTIVE:
To explore the genetic etiology of a child with Pitt-Hopkins syndrome.
METHODS:
A child who had presented at the Medical Genetics Center of Gansu Provincial Maternal and Child Health Care Hospital on February 24, 2021 and his parents were selected as the study subjects. Clinical data of the child was collected. Genomic DNA was extracted from peripheral blood samples of the child and his parents and subjected to trio-whole exome sequencing (trio-WES). Candidate variant was verified by Sanger sequencing. Karyotype analysis was also carried out for the child, and her mother was subjected to ultra-deep sequencing and prenatal diagnosis upon her subsequent pregnancy.
RESULTS:
The clinical manifestations of the proband included facial dysmorphism, Simian crease, and mental retardation. Genetic testing revealed that he has carried a heterozygous c.1762C>T (p.Arg588Cys) variant of the TCF4 gene, for which both parents had a wild-type. The variant was unreported previously and was rated as likely pathogenic based on the guidelines of the American College of Medical Genetics and Genomics (ACMG). Ultra-deep sequencing indicated that the variant has a proportion of 2.63% in the mother, suggesting the presence of low percentage mosaicism. Prenatal diagnosis of amniotic fluid sample suggested that the fetus did not carry the same variant.
CONCLUSION
The heterozygous c.1762C>T variant of the TCF4 gene probably underlay the disease in this child and has derived from the low percentage mosaicism in his mother.

OBJECTIVE:
To explore the genetic basis for a child with congenital heart disease (CHD) and global developmental delay (GDD).
METHODS:
A child who was hospitalized at the Department of Cardiac Surgery of Fujian Children's Hospital on April 27, 2022 was selected as the study subject. Clinical data of the child was collected. Umbilical cord blood sample of the child and peripheral blood samples of his parents were collected and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing and bioinformatic analysis.
RESULTS:
The child, a 3-year-and-3-month-old boy, had manifested cardiac abnormalities and developmental delay. WES revealed that he had harbored a nonsense variant of c.457C>T (p.Arg153*) in the NONO gene. Sanger sequencing showed that neither of his parents has carried the same variant. The variant has been recorded by the OMIM, ClinVar and HGMD databases, but not in the normal population databases of 1000 Genomes, dbSNP and gnomAD. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), it was rated as a pathogenic variant.
CONCLUSION
The c.457C>T (p.Arg153*) variant of the NONO gene probably underlay the CHD and GDD in this child. Above finding has expanded the phenotypic spectrum of the NONO gene and provided a reference for the clinical diagnosis and genetic counseling for this family.

OBJECTIVE:
To explore the genetic etiology for a child with profound intellectual disabilities and obvious behavioral abnormalities.
METHODS:
A male child who had presented at the Zhongnan Hospital of Wuhan University on December 2, 2020 was selected as the study subject. Peripheral blood samples of the child and his parents were collected and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing. Short tandem repeat (STR) analysis was carried out to determine its parental origin. The splicing variant was also validated in vitro with a minigene assay.
RESULTS:
WES results revealed that the child had harbored a novel splicing variant of c.176-2A>G in the PAK3 gene, which was inherited from his mother. The results of minigene assay have confirmed aberrant splicing of exon 2. According to the guidelines from the American College of Medical Genetics and Genomics, it was classified as a pathogenic variant (PVS1+PM2_Supporting+PP3).
CONCLUSION
The novel splicing variant c.176-2A>G of the PAK3 gene probably underlay the disorder in this child. Above finding has expanded the variation spectrum of the PAK3 gene and provided a basis for genetic counseling and prenatal diagnosis for this family.

Objective: To investigate the association between screen exposure and language skills in children aged 2-5 years. Methods: There were 299 children aged 2-5 years, recruited by convenience sampling from those who visited the Center of Children's Healthcare, Children's Hospital, Capital Institute of Pediatrics for routine physical examination from November 2020 to November 2021. Their development status were evaluated by the children neuropsychological and behavioral scale (revision 2016). A self-designed questionnaire for parents was conducted to collect demographic and socioeconomic information and screen exposure characteristics (time and quality). One-way ANOVA and independent sample t test were applied to compare the differences in language development quotient of children with different screen exposure time and quality. Multiple linear regression was used to analyze the correlation between screen exposure time and quality with language developmental quotient. Multivariate Logistic regression was used to analyze the risk of language underdevelopment in children with different screen exposure time and quality. Results: Among 299 children, 184 (61.5%) were boys and 115 (38.5%) were girls, with the age of (3.9±1.1) years. The number of children with daily screen time <60, 60-120 and>120 min was 163 children (54.5%), 86 children (28.8%) and 50 children (16.7%), respectively, with the language development quotients of 94±13, 90±13, 84±14, respectively, demonstrating a statistically significant difference (F=8.92, P<0.001). Logistic regression analysis revealed that screen exposure time of 60-120 and >120 min per day were both risk factors for children's language developmental quotients (OR=2.28, 95%CI 1.00-5.17, P=0.043; OR=3.96, 95%CI 1.86-9.17, P<0.001), and co-viewing and exposure to educational programs were both protective factors for children's language developmental quotients (OR=0.48, 95%CI 0.25-0.91, P=0.024, OR=0.36, 95%CI 0.19-0.70, P=0.003). Conclusions: Excessive exposure screen time and inappropriate screen exposure habits are associated with children's poorer language development. Screen exposure time should be limited and screen use should be rational to promote children's language skills.

OBJECTIVE:
To test the reliability and validity of the Chinese version of adverse childhood experiences international questionnaire (ACE-IQ) in Chinese parents of preschool children.
METHODS:
The parents of preschool children in 6 kindergartens in Tongzhou District of Beijing were selected by stratified random cluster sampling, and the Chinese version of ACE-IQ after translation and adaptation was used for survey online. The collected data were randomly divided into two parts. One part of the data (n=602) was used for exploratory factor analysis (EFA), to screen items and evaluate structural validity, and then form the final Chinese version of ACE-IQ. The other part of the data (n=700) was used for confirmatory factor analysis (CFA), criterion validity analysis and reliability analysis. At the same time, experts investigation method was used to evaluate the content validity of the final Chinese version of ACE-IQ.
RESULTS:
After deleting four items of collective violence, the Chinese version of ACE-IQ with twenty-five items indicated good structural, criterion and content validity. Analysis results showed that the Chinese version of ACE-IQ presented a seven-factor model dimension, namely emotional neglect, physical neglect, family dysfunction, family violence, emotional and physical abuse, sexual abuse and violence outside the home, and the total score of the binary version of ACE-IQ Chinese version was positively correlated with the total score of childhood trauma questionaire-28 item short form (CTQ-SF, r=0.354, P < 0.001) and the center for epidemiological studies depression scale (CES-D, r=0.313, P < 0.001) respectively. Results from five experts showed that the item-level content validity index (I-CVI) of 25 items was between 0.80 and 1.00, and the average of all I-CVIs on the scale (S-CVI/Ave) of the scale was 0.984. At the same time, the internal consistency (Cronbach's α coefficient) of the whole scale was 0.818, and the split-half reliability (Spearman-Brown coefficient) was 0.621, which demonstrated good reliability.
CONCLUSION
This study has formed a Chinese version of ACE-IQ with 25 items and 7 dimensions, which has good reliability and validity among the parents of preschool children in China. It can be used as an evaluation instrument for measuring the minimum threshold of the adverse childhood experiences in the parents of preschool children in the cultural background of China.

Journal of Southern Medical University 2023;43(4):604-610
OBJECTIVE:
To compare the parental acceptance of dental treatment under general anesthesia and deep sedation in children and assess the changes in postoperative oral health-related quality of life and treatment efficacy.
METHODS:
The parents of 131 children undergoing dental treatment in the Department of Stomatology of Sichuan Provincial People's Hospital from January, 2022 to June, 2022 were surveyed using a questionnaire of children's advanced oral behavior management, and 83 children receiving general anesthesia or deep sedation for dental treatment between January, 2018 and December, 2021 were also investigated for changes in quality of life after the treatment using a questionnaire. The treatment efficacy was assessed at the 1-year follow-up visit in 149 children who received dental treatment under general anesthesia or deep sedation during the same period.
RESULTS:
The survey of perantal acceptance showed that 62.6% of the parents preferred deep sedation, 29.01% preferred general anesthesia, and 8.4% preferred compulsory treatment. Dental treatments under general anesthesia and deep sedation both significantly improved oral health-related quality of life of the children. While dental surgeries under general anesthesia resulted in the most significant improvement of pain symptoms, deep sedation was associated with both obvious relief of the children's pain symptoms and reduction of the parents' pressure level. No significant difference was found in the efficacy of treatments under general anesthesia and deep sedation at the 1-year follow-up.
CONCLUSION
Dental treatment in children under deep sedation has the highest parental acceptance, followed by treatment under general anesthesia, and the acceptance of compulsory treatment is the lowest. The treatments under general anesthesia and deep sedation significantly improve the quality of life of the children and their parents and both have good treatment efficacy.

Chinese Journal of Medical Genetics 2023;40(3):364-367
OBJECTIVE:
To explore the clinical and molecular characteristics of a child with Congenital disorders of glycosylation (CDG).
METHODS:
A 4-month-old boy who had presented at the Children's Hospital Affiliated to Zhejiang University Medical School on December 31, 2019 due to feeding difficulties after birth was selected as the study subject. High-throughput sequencing was carried out for the patient, and real-time qPCR was used for validating the suspected deletion fragments and the carrier status of other members of his family.
RESULTS:
High-throughput sequencing revealed that the child had lost the capture signal for chrX: 153 045 645-153 095 809 (approximately 50 kb), which has involved 4 OMIM genes including SRPK3, IDH3G, SSR4 and PDZD4. qPCR verified that the copy number in this region was zero, while that of his elder brother and parents was all normal.
CONCLUSION
The deletion of the fragment containing the SSR4 gene in the Xq28 region probably underlay the SSR4-CDG in this child.

9.Asthma management and asthma control level in children.
Chinese Journal of Contemporary Pediatrics 2023;25(1):73-79
OBJECTIVES:
To investigate the influencing factors for asthma management and asthma control level in children.
METHODS:
A total of 202 children with a confirmed diagnosis of asthma were enrolled. The questionnaire of asthma control level and family management was used to investigate the influencing factors for asthma control level and the indicators of family management. The awareness of childhood asthma and its management was analyzed among the parents, as well as the influence on asthma control level in children, and the association between them was analyzed.
RESULTS:
Compared with the non-complete control group, the complete control group had significantly longer course of asthma and treatment time (P<0.05). The proportions of asthma attacks ≥3 times and aerosol treatment for asthma attacks >3 times in one year in the complete control group were significantly lower than those in the non-complete control group (P<0.05). The complete control group had a significantly lower proportion of children with frequent respiratory infection, wheezing during respiratory infection, or a family history of allergic diseases (P<0.05). The parents in the complete control group had significantly stronger awareness of short-term escalation to asthma medication after respiratory infection and significantly enhanced management of maintenance medication (P<0.05). Compared with the complete control group, the non-complete control group had a significantly higher proportion of children with abnormal pulmonary function at the initial stage (P<0.05). The level of asthma control in children was associated with short-term escalation to asthma medication during respiratory infection and initial lung function (P<0.05).
CONCLUSIONS
The level of asthma control in children is closely associated with the severity of asthma and the comprehensive management of childhood asthma. Early treatment and family management, especially escalation to asthma medication during the early stage of respiratory infection, are of great importance in asthma control.
