We used chromosomal microarray analysis to identify the microdeletion 3q13.33q21.2. Next-generation sequencing was utilized to exclude the presence of allelic mutations within the microdeletion region 3q13.33q21.2, which may have a potential role in the development of disease in patients affected with secondary genetic alterations.

Patient 6 was diagnosed with attention deficit hyperactivity disorder, short stature, intellectual disability, and concurrent epilepsy. By investigating the 3q13.33q21.2 band of the University of California, Santa Cruz database, we screened out the genes related to developmental delay and intellectual disability, including ADCY5 SEMA5B andKPNA1, which were highly suspected to be related to intelligence. This region also involves CASR, a gene that has been reported to be associated with epilepsy. The ADCY5 and SEMA5B genes may be key genes to cause neurodevelopmental disorder.

Human chorionic gonadotropin pretreatment in HS is proposed to decrease the severity of the anomaly and improve the clinical outcome of surgery. The underlying mechanisms that drive these outcomes have not been explored. Few studies have explored the endocrine signaling and pathways which lead to the development of the condition.

Serum samples from all these children and preputial skin samples taken during surgery were used in the analysis. The hormonal milieu was normal in all children in our cohort. A comparison of previously reported genes with our cohort sequencing revealed changes in several major pathways involved in cell proliferation and differentiation, cell signaling, angiogenesis, and immune response pathways. Compared with healthy controls, HS subjects had 152 differentially expressed genes. Of these, 93 genes were up-regulated, and 59 genes were found to be significantly down-regulated.

Examination showed a failure to thrive, microcephaly, rachitic rosary, checkerboard and phylloid type of pigmentary mosaicism, fundus showed disc pallor with generalized narrowing of arterioles, bilateral retinitis pigmentosa, spasticity and dystonia, brisk reflexes, extensor plantar, and left choreoathetoid movements. Investigations showed hypocalcemia (7.8 mg/dL), normal phosphorus (3.9 mg/dL), elevated alkaline phosphatase (508.8 U/L), elevated parathyroid hormone (513.35 pg/mL), low 1,25-dihydroxy-vitamin D (9.93 pg/mL), and normal renal function. The child had metabolic acidosis, elevated ammonia (403.9 micromol/L), lactate (95 mg/dL, normal range 4.5-19.8 mg/dL), and creatine phosphokinase (432 U/L) level, and normal tandem mass spectroscopy. X-ray wrist showed healing vitamin deficiency rickets. Abnormal electroencephalogram was suggestive of low voltage activity.

A 6-year-old girl, whose parents were first-cousin consanguineous, was referred to the pediatric hematology department due to growth retardation, thrombocytopenia, neutropenia, and anemia. The patient had low-set ears, pectus excavatum inferiorly, and cafe-au-lait spots. In whole-exome analysis, p.K385T (c.1154A &gt; C) variant in the RASA3 gene was detected as homozygous. The amino acid position of the alteration is located in the conserved and ordered region, corresponding to the Ras GTPase activation domain (Ras-GAP) in the center of the protein. Importantly, most of in silico prediction tools of pathogenicity predicts the variant as damaging. RASopathies, which are characterized by many common clinical findings, such as atypical facial features, growth delays, and heart defects, are a group of rare genetic diseases caused by mutations in the genes involved in the Ras-MAPK pathway. The findings in this patient were consistent with the RASopathy-like phenotype and bone marrow failure. Interestingly, enrichment of RASopathy genes was observed in the RASA3 protein–protein interaction network. Furthermore, the subsequent topological clustering revealed a putative function module, which further implicates RASA3 in this disease as a novel potential causative gene. In this context, the detected RASA3 mutation could be manifesting itself clinically as the observed phenotype by disrupting the functional cooperation between the RASA3 protein and its interaction partners. Relatedly, current literature also supports the obtained findings. Overall, this study provides new insights into RASopathy and put forward the RASA3 gene as a novel candidate gene for this disease group.","PeriodicalId":16695,"journal":{"name":"Journal of pediatric genetics","volume":"7 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134907843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several factors such as various genetic backgrounds are associated with the pathogenesis of ITP. Interleukin (IL)-10 is a complicated cytokine that has a role in tumor progression, antitumor immunity, and immune system regulation. rs1800890 is an IL-10 single nucleotide polymorphism linked to lower levels of IL-10. A total of 67 patients with ITP and 70 healthy individuals (controls) were considered in this study. The IL-10 polymorphism was detected by the amplification refractory mutation system–polymerase chain reaction technique. According to our analysis, individual carriers of the AA genotype were less likely to develop ITP. The AT genotype was more common in patients with ITP in comparison to the control group. However, there was no significant association between rs1800890 genotypes (p = 0.775, odds ratio =1.517, 95%) in the acute and chronic groups. We observed that women had a higher mean frequency of this polymorphism (p = 0.0012). The rs1800890 AA genotype was associated with the highest platelet counts. However, the mean platelet volume and platelet distribution width values among alleles of the polymorphisms did not vary significantly. The IL-10 rs1800890 polymorphism may have a role in idiopathic thrombocytopenic purpura etiology. As a result, more research with a larger number of sample sizes is suggested.","PeriodicalId":16695,"journal":{"name":"Journal of pediatric genetics","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135193912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
