Introduction

Zinc finger nuclear factor involved in transcription by regulating chromatin structure and organization (PubMed:20219459, PubMed:21570965). Involved in the pluripotency and differentiation of embryonic stem cells by regulating SOX2, POU5F1/OCT4, and NANOG (PubMed:21570965). By binding PBX1, prevents the heterodimerization of PBX1 and HOXA9 and their binding to DNA (By similarity). Regulates neuronal development and neural cell differentiation (PubMed:21570965).

ABSTRACTWeiss‐Kruszka syndrome (WKS) is a rare genetic disorder characterized by metopic ridging, ptosis, arched eyebrows, down slanting palpebral fissures, abnormalities in the corpus callosum, cardiac malformations, and variable neurodevelopmental delay. To date, 32 individuals with a diagnosis of WKS have been reported in the literature. The syndrome is caused by a heterozygous pathogenic variant in the ZNF462 gene or a deletion of the 9p31.2 region involving ZNF462. There is significant phenotypic heterogeneity and intrafamilial variability among these patients. Our study reviewed nine patients from seven unrelated families and identified seven novel heterozygous ZNF462 variants through exome sequencing. GestaltMatcher analysis of our cohort's facial images, alongside previously published images of ZNF462 patients, demonstrated a high degree of facial similarity. Further longitudinal research is needed to delineate this rare condition's long‐term health implications and adult‐onset features.

Phenotypic spectrum in Weiss-Kruszka syndrome caused by ZNF462 variants: Three new patients and literature review

Review

Weiss-Kruszka Syndrome (WSKA) is caused by pathogenic variants in ZNF462 representing a rare autosomal dominant congenital anomaly syndrome. It is characterized by global developmental delay, hypotonia, feeding difficulties, and craniofacial abnormalities, documented in fewer than 30 patients. ZNF462, located on chromosome 9p31.2, is a transcription factor and has an important role during embryonic development and chromatin remodelling. Here, we report three new patients with WSKA, Through whole exome sequencing (WES) analysis, we identified two novel variants in three patients, two of whom are siblings. These variants (c.3078dup, p.Val1027Cysfs5 and c.4792A > T p.Lys1598*) in the ZNF462 gene are likely resulting in haploinsufficiency. Our patients help to further delineate the phenotype, genotype and potential therapeutic management strategies for WSKA. Since we report a second WSKA patient with an autoimmune disease further clinical and functional studies are needed to elucidate the association between this chromatin remodelling disorder and the development of autoimmune problems. In the future, collaborative efforts are encouraged to develop an episignature for WSKA, given the gene's function and associated patient phenotypes. This new technology has the potential to provide valuable insights into the disorder.

Prenatal hypoxia (PH) is one of the most common complications of obstetrics and is closely associated with many neurological disorders such as depression, anxiety, and cognitive impairment. Our previous study found that Zfp462 heterozygous (Het) mice exhibit significant anxiety-like behavior. Interestingly, offspring mice with PH also have anxiety-like behaviors in adulthood, accompanied by reduced expression of Zfp462 and increased expression of miR-377-3p; however, the exact regulatory mechanisms remain unclear. In this study, western blotting, gene knockdown, immunofluorescence, dual-luciferase reporter assay, immunoprecipitation, cell transfection with miR-377-3p mimics or inhibitors, quantitative real-time PCR, and rescue assay were used to detect changes in the miR-377-3p-Zfp462-Pbx1 (pre-B-cell leukemia homeobox1) pathway in the brains of prenatal hypoxic offspring to explain the pathogenesis of anxiety-like behaviors. We found that Zfp462 deficiency promoted Pbx1 protein degradation through ubiquitination and that Zfp462 Het mice showed downregulation of the protein kinase B (PKB, also called Akt)-glycogen synthase kinase-3β (GSK3β)-cAMP response element-binding protein (CREB) pathway and hippocampal neurogenesis with anxiety-like behavior. In addition, PH mice exhibited upregulation of miR-377-3p, downregulation of Zfp462/Pbx1-Akt-GSK3β-CREB pathway activity, reduced hippocampal neurogenesis, and an anxiety-like phenotype. Intriguingly, miR-377-3p directly targets the 3'UTR of Zfp462 mRNA to regulate Zfp462 expression. Importantly, microinjection of miR-377-3p antagomir into the hippocampal dentate gyrus of PH mice upregulated Zfp462/Pbx1-Akt-GSK3β-CREB pathway activity, increased hippocampal neurogenesis, and improved anxiety-like behaviors. Collectively, our findings demonstrated a crucial role for miR-377-3p in the regulation of hippocampal neurogenesis and anxiety-like behaviors via the Zfp462/Pbx1-Akt-GSK3β-CREB pathway. Therefore, miR-377-3p could be a potential therapeutic target for anxiety-like behavior in prenatal hypoxic offspring.
