Discovery of a novel mutation F184S (c.551T>C) in GATA4 gene causing congenital heart disease in a consanguineous Saudi family. Heliyon 2024; 10:e37177. [PMID: 39286212 PMCID: PMC11403501 DOI: 10.1016/j.heliyon.2024.e37177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 08/25/2024] [Accepted: 08/28/2024] [Indexed: 09/19/2024] Open
Abstract
Background & aim Congenital heart disease (CHD) is the most common cause of non-infectious deaths in infants worldwide. However, the molecular mechanisms underlying CHD remain unclear. Approximately 30 % of the causes are believed to be genetic mutations and chromosomal abnormalities. In this study, we aimed to identify the genetic causes of CHD in consanguineous families. Methods Fourth-generation pedigrees with CHD were recruited. The main cardiac features of the patient included absence of the right pulmonary artery and a large dilated left pulmonary artery. To determine the underlying genetic cause, whole-exome sequencing was performed and subsequently confirmed using Sanger sequencing and different online databases to study the pathogenesis of the identified gene mutation. An in-silico homology model was created using the Alphafold homology model structure of GATA4 (AF-P43694-F1). The missense3D online program was used to evaluate the structural alterations. Results We identified a deleterious mutation c.551T > C (p.Phe184Ser) in GATA4. GATA4 is a highly conserved zinc-finger transcription factor, and its continuous expression is essential for cardiogenesis during embryogenesis. The in-silico model suggested a compromised binding efficiency with other proteins. Several variant interpretation algorithms indicated that the F184S missense variant in GATA4 is damaging, whereas HOPE analysis indicated the functional impairment of DNA binding of transcription factors and zinc-ion binding activities of GATA4. Conclusion The variant identified in GATA4 appears to cause recessive CHD in the family. In silico analysis suggested that this variant was damaging and caused multiple structural and functional aberrations. This study may support prenatal screening of the fetus in this family to prevent diseases in new generations.

Abstract
The contamination of food and feed by mycotoxins, particularly zearalenone (ZEA) and deoxynivalenol (DON), is a global issue. Prenatal exposure to ZEA and DON can result in congenital cardiac malformations in fetuses. Addressing the prevention and mitigation of embryonic cardiotoxicity caused by these toxins is crucial. Citrus limonoid nomilin (NOM) is an extract known for its pathological properties in various diseases. This study investigated the potential mechanism of NOM in mitigating cardiotoxicity caused by ZEA and DON co-exposure in a zebrafish model. The findings indicated that NOM pretreatment alleviated cardiac developmental toxicity induced by ZEA and DON and normalized the expression of key genes involved in heart development, including gata4, vmhc, nkx2.5, and sox9b. Co-exposure to NOM, ZEA, and DON enhanced SOD and catalase activity, increased glutathione levels, and reduced ROS and malondialdehyde production. Furthermore, NOM reduced cardiac oxidative damage by activating the Keap1/Nrf2 signaling pathway. In summary, this study offers new insights for preventive interventions against congenital heart disease caused by mycotoxin exposure.

Abstract
Although atrial septal defects (ASD) can be subdivided based on their anatomical location, an essential aspect of human genetics and genetic counseling is distinguishing between isolated and familiar cases without extracardiac features and syndromic cases with the co-occurrence of extracardiac abnormalities, such as developmental delay. Isolated or familial cases tend to show genetic alterations in genes related to important cardiac transcription factors and genes encoding for sarcomeric proteins. By contrast, the spectrum of genes with genetic alterations observed in syndromic cases is diverse. Currently, it points to different pathways and gene networks relevant to the dysregulation of cardiomyogenesis and ASD pathogenesis. Therefore, this chapter reflects the current knowledge and highlights stable associations observed in human genetics studies. It gives an overview of the different types of genetic alterations in these subtypes, including common associations based on genome-wide association studies (GWAS), and it highlights the most frequently observed syndromes associated with ASD pathogenesis.

Abstract
Introduction: Congenital heart disease (CHD) is the most common congenital abnormality and the main cause of infant mortality worldwide. Some of the mutations that occur in the GATA4 gene region may result in different types of CHD. Here, we report our in silico analysis of gene variants to determine the effects of the GATA4 gene on the development of CHD.
Methods: Online 1000 Genomes Project, ExAC, gnomAD, GO-ESP, TOPMed, Iranome, GME, ClinVar, and HGMD databases were drawn upon to collect information on all the reported GATA4 variations.The functional importance of the genetic variants was assessed by using SIFT, MutationTaster, CADD,PolyPhen-2, PROVEAN, and GERP prediction tools. Thereafter, network analysis of the GATA4protein via STRING, normal/mutant protein structure prediction via HOPE and I-TASSER, and phylogenetic assessment of the GATA4 sequence alignment via ClustalW were performed.
Results: The most frequent variant was c.874T>C (45.58%), which was reported in Germany.Ventricular septal defect was the most frequent type of CHD. Out of all the reported variants of GATA4,38 variants were pathogenic. A high level of pathogenicity was shown for p.Gly221Arg (CADD score=31), which was further analyzed.
Conclusion: The GATA4 gene plays a significant role in CHD; we, therefore, suggest that it be accorded priority in CHD genetic screening.

Abstract
Congenital heart disease (CHD) is the most common type of developmental defect, with high rates of morbidity in infants. The transcription factor GATA‑binding factor 4 (GATA4) has been reported to serve a critical role in embryogenesis and cardiac development. Our previous study reported a heterozygous GATA4 c.1306C>T (p.H436Y) mutation in four Chinese infants with congenital heart defects. In the present study, functional analysis of the GATA4 H436Y mutation was performed in vitro. The functional effect of GATA4 mutation was compared with GATA4 wild‑type using a dual‑luciferase reporter assay system and immunofluorescence. Electrophoretic mobility‑shift assays were performed to explore the binding affinity of the mutated GATA4 to the heart and neural crest derivatives expressed 2 (HAND2) gene. The results revealed that the mutation had no effect on normal nuclear localization, but resulted in diminished GATA‑binding affinity to HAND2 and significantly decreased gene transcriptional activation. These results indicated that this GATA4 mutation may not influence cellular localization in transfected cells, but may affect the affinity of the GATA‑binding site on HAND2 and decrease transcriptional activity, thus suggesting that the GATA4 mutation may be associated with the pathogenesis of CHD.

Abstract
Transcriptional factors and signaling factors in the second heart field (SHF) contribute to cardiac development. However, the associations of intronic gene variants in the SHF with congenital heart disease (CHD) remain ununderstood. Ten single nucleotide polymorphisms (SNPs) from our previous sequencing data were selected and then genotyped in 383 CHD patients and 384 healthy controls in a Chinese population. Genotype analyses revealed that minor alleles in TBX1: rs12165908 C > G [odds ratio (OR) = 2.64; 95% confidence interval (CI) = 1.87-3.73, p = 3.03 × 10-8] and GATA6: rs143085291 C > T (OR = 2.49; 95% CI = 1.18-5.29, p = 0.01) increased CHD risk significantly. Meanwhile, FGF10: rs78454549 T > C and GATA4: rs13275657 A>G polymorphisms were significantly associated with increased risk of simple CHDs. The minor allele C in GATA4: rs17153694 T > C increased the risk of tetralogy of Fallot, whereas minor alleles in TBX1: rs41298006 G>A, FGF10: rs75629618 C>T, FGF10: rs10461755 G>A, FGF10: rs75632187 A>G, and FGF10: rs12518964 G > A were associated with increased risk of single ventricle. The minor allele T in rs143085291 in GATA6 enhancer decreased the transcription level in luciferase assay. Our findings suggest that intronic SNPs in transcriptional factors and signaling factors in the SHF are significantly associated with increased risk of different CHD types.

Abstract
Background Tight control of endosome trafficking is essential for the generation of a normally patterned embryo. Recent studies have found that VPS50 is a key ingredient in EARP which is required for recycling of internalized TfRs to the cell surface and dense-core vesicle maturation. However, the role of VPS50 in embryogenesis and human physiology are poorly understood. Results We identified a rare missense heterozygous VPS50 mutation (p. Gly169Val) in NTDs by high-throughput sequencing. In vitro functional analysis demonstrated that the p. Gly169Val was a loss-of-function mutation, delaying transferrin recycling and altering its interaction with VPS53. Using WISH during zebrafish embryogenesis, we demonstrated that vps50 gene was expressed throughout the early embryo, especially in the head. Abnormal body axis phenotypes were observed in those vps50 knock-down zebrafishes. Further rescue study in zebrafish suggested that the mutation displayed loss-of-function effects comparing with wild-type VPS50. Conclusions These findings thus demonstrated that the functional mutations in VPS50 might contribute to neurodevelopmental disorder and highlighted the critical importance of VPS50 function in cellular and organismal physiology.

Abstract
OBJECTIVE To establish a mouse model of H435Y mutation of Gata4 gene using CRISPR/Cas9- mediated gene targeting. METHODS The single-stranded guide RNA (sgRNA) specific to the H435Y loci of Gata4 gene was designed based on the sequence of Gata4 gene. After activity assessment, the active sgRNA and Cas9 were in vitro transcribed into RNA and microinjected along with the donor DNA fragment with point mutations into fertilized mouse eggs. The microinjected eggs were transferred into pseudopregnant mice to obtain the F0 generation mice with the target Gata4 gene mutation confirmed by PCR and gene sequencing. Gata4 gene mutations in the offsprings of the F0 generation mice were analyzed. RESULTS Gene sequencing confirmed the successful establishment of mouse models carrying H435Y mutation of Gata4 gene in 4 of the F0 generation mice. The positive F0 generation mice were crossed with wild-type C57BL/6J mice to obtain the F1 generation mice, and PCR confirmed the presence of H435Y mutations of Gata4 gene in 6 of the F1 mice. Then F2 generation mice were obtained by F1 generation matting with each other. PCR showed that H435Y mutation of Gata4 gene in F2 mice was found, indicating the mousemodel of Gata4 gene mutation in H435Y was established and propagated successfully. CONCLUSIONS We successfully established Gata4 gene H435Y mutant mouse models using CRISPR/Cas9 technique.

Abstract
BACKGROUND The mutations in GATA4 gene induce inherited atrial and ventricular septation defects, which is the most frequent forms of congenital heart defects (CHDs) constituting about half of all cases. METHOD We have performed High resolution melting (HRM) mutation scanning of GATA4 coding exons of nonsyndrome 100 patients as a case group including 39 atrial septal defects (ASD), 57 ventricular septal defects (VSD) and four patients with both above defects and 50 healthy individuals as a control group. Our samples are categorized according to their HRM graph. The genome sequencing has been done for 15 control samples and 25 samples of patients whose HRM analysis were similar to healthy subjects for each exon. The PolyPhen-2 and MUpro have been used to determine the causative possibility and structural stability prediction of GATA4 sequence variation. RESULTS The HRM curve analysis exhibit that 21 patients and 3 normal samples have deviated curves for GATA4 coding exons. Sequencing analysis has revealed 12 nonsynonymous mutations while all of them resulted in stability structure of protein 10 of them are pathogenic and 2 of them are benign. Also we found two nucleotide deletions which one of them was novel and one new indel mutation resulting in frame shift mutation, and 4 synonymous variations or polymorphism in 6 of patients and 3 of normal individuals. Six or about 50% of these nonsynonymous mutations have not been previously reported. CONCLUSION Our results show that there is a spectrum of GATA4 mutations resulting in septal defects.

GATA4 Variants in Individuals With a 46,XY Disorder of Sex Development (DSD) May or May Not Be Associated With Cardiac Defects Depending on Second Hits in Other DSD Genes. Front Endocrinol (Lausanne) 2018; 9:142. [PMID: 29670578 PMCID: PMC5893726 DOI: 10.3389/fendo.2018.00142] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Accepted: 03/16/2018] [Indexed: 12/18/2022] Open
Abstract
Disorders of sex development (DSD) consist of a wide range of conditions involving numerous genes. Nevertheless, about half of 46,XY individuals remain genetically unsolved. GATA4 gene variants, mainly related to congenital heart defects (CHD), have also been recently associated with 46,XY DSD. In this study, we characterized three individuals presenting with 46,XY DSD with or without CHD and GATA4 variants in order to understand the phenotypical variability. We studied one patient presenting CHD and 46,XY gonadal dysgenesis, and two patients with a history of genetically unsolved 46,XY DSD, also known as male primary hypogonadism. Mutation analysis was carried out by candidate gene approach or targeted gene panel sequencing. Functional activity of GATA4 variants was tested in vitro on the CYP17 promoter involved in sex development using JEG3 cells. We found two novel and one previously described GATA4 variants located in the N-terminal zinc finger domain of the protein. Cys238Arg variant lost transcriptional activity on the CYP17 promoter reporter, while Trp228Cys and Pro226Leu behaved similar to wild type. These results were in line with bioinformatics simulation studies. Additional DSD variations, in the LRP4 and LHCGR genes, respectively, were identified in the two 46,XY individuals without CHD. Overall, our study shows that human GATA4 mutations identified in patients with 46,XY DSD may or may not be associated with CHD. Possible explanations for phenotypical variability may comprise incomplete penetrance, variable sensitivity of partner genes, and oligogenic mechanisms.

Abstract
Conotruncal heart defects (CTDs) are severe malformations of outflow tract with heterogeneous morphology. Several missense variants of CITED2 have been identified to cause CTDs in recent researches. In this study, we screened the coding regions of CITED2 in 605 Chinese children with CTDs and found two possible pathogenic mutant sites: p.Q117L and p.T257A, both located in the conserved regions of CITED2. Then, we investigated the biological and functional alterations of them. Western blotting showed low level of protein expression of mutant Q117 and T257A compared with wild-type CITED2. Dual-luciferase reporter assay demonstrated that mutant Q117 and T257A decreased the ability of CITED2 to modulate the expression of paired-like homeodomain transcription factor 2 gamma (PITX2C), which are closely related to cardiac growth and left-right patterning. Meanwhile, T257A also exhibited impaired ability to mediate vascular endothelial growth factor expression, another gene closely associated with the normal development of cardiovascular system. Three-dimensional molecular conformation showed reduced hydrogen bond between Asp254 and mutant Thr257, indicating the weakened stability and binding ability of CITED2. All these results suggest that CITED2 mutations in conserved regions lead to disease-causing biological and functional changes and may contribute to the occurrence of CTDs.

Abstract
BACKGROUND GATA4 gene is a cardiac transcriptional factor playing important role in cardiac formation and development. Three GATA4 gene mutations, 99 G>T, 487 C>T, and 354 A>C, have been reported in congenital heart disease (CHD). Therefore, a meta-analysis was performed to explore the associations between 99 G>T, 487 C>T, or 354 A>C mutations and the risk of CHD. METHODS We searched the relevant studies in electronic databases, including ISI Science Citation Index, Embase, PubMed, CNKI, and Wan fang, from January 2006 to March 2016. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to estimate the associations between 99 G>T, 487 C>T, or 354 A>C mutations and the risk of CHD. RESULTS A total of 11 studies including 2878 CHD cases and 3339 controls were evaluated. There was no significant association between GATA4 99 G>T (OR = 1.22, 95% CI = 0.74-2.01, P = .43) or 487 C>T (OR = 1.16, 95% CI = 0.48-2.78, P = .74) mutations and the risk of CHD, whereas GATA4 354 A>C (OR = 1.49, 95% CI = 1.15-1.93, P = .003) mutation was significantly associated with CHD risk. Subgroup analysis was further performed for GATA4 99 G>T, 487 C>T, and 354 A>C mutations based on sample size and ethnicity, and no significant association between GATA4 99 G>T or 487 C>T mutations and the risk of CHD was found in all subgroups, whereas GATA4 354 A>C mutation was significantly associated with CHD risk in large-sample-size and Asian subgroups. However, subgroup analysis by types of CHD indicated that there was no significant association between GATA4 354 A>C mutation and the risk of ventricular septal defects. CONCLUSIONS Our findings suggested that GATA4 99 G>T and 487 C>T mutations may not be related to the incidence of CHD. However, GATA4 354 A>C mutation was significantly associated with CHD risk.

Abstract
Cardiac rehabilitation is an important part of daily routine for cardiac disorder patients in adults. However, pediatric rehabilitation is an emerging field, and is totally different and new field in case of pediatric patients. The main reason of variability is the Pediatric patients differ from adult patients in several ways. The main difference is they are dependent on their parents for meeting their needs, including for transportation and following of rehabilitation initiatives. Furthermore, rehabilitation initiatives are often connected to large urban university hospitals and unavailable to children whose parents cannot bring them for exercise training on a regular basis. The present review article is focused on these aspects of rehabilitation during congenital heart disease.
