ZNF142 mutation causes sex-dependent neurologic disorder. J Med Genet 2024; 61:566-577.

Abstract
BACKGROUND Sex-specific predilection in neurological diseases caused by mutations in autosomal genes is a phenomenon whose molecular basis is poorly understood. We studied females of consanguineous Bedouin kindred presenting with severe global developmental delay and epilepsy. METHODS Linkage analysis, whole exome sequencing, generation of CRISPR/cas9 knock-in mice, mouse behaviour and molecular studies RESULTS: Linkage analysis and whole exome sequencing studies of the affected kindred delineated a ~5 Mbp disease-associated chromosome 2q35 locus, containing a novel homozygous frameshift truncating mutation in ZNF142, in line with recent studies depicting similar ZNF142 putative loss-of-function human phenotypes with female preponderance. We generated knock-in mice with a truncating mutation adjacent to the human mutation in the mouse ortholog. Behaviour studies of homozygous Zfp142R1508* mice showed significant phenotype only in mutant females, with learning and memory deficits, hyperactivity and aberrant loss of fear of open spaces. Bone marrow and spleen of homozygous Zfp142R1508* mice showed depletion of lymphoid and haematopoietic cells, mostly in females. RT-PCR showed lower expression of Zpf142 in brain compartments of female versus male wild-type mice. RNA-seq studies of hippocampus, hypothalamus, cortex and cerebellum of female wild-type versus homozygous Zfp142R1508* mice demonstrated differentially expressed genes. Notably, expression of Taok1 in the cortex and of Mllt6 in the hippocampus was downregulated in homozygous Zfp142R1508* mice. Taok1 mutations have been associated with aberrant neurodevelopment and behaviour. Mllt6 expression is regulated by sex hormones and Mllt6 null-mutant mice present with haematopoietic, immune system and female-specific behaviour phenotypes. CONCLUSION ZNF142 mutation downregulates Mllt6 and Taok1, causing a neurodevelopmental phenotype in humans and mice with female preponderance.

[PMID: 38754172 DOI: 10.1016/j.sbi.2024.102836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 04/21/2024] [Accepted: 04/23/2024] [Indexed: 05/18/2024]
Abstract
C2H2 zinc-finger (ZF) proteins form the largest family of DNA-binding transcription factors coded by mammalian genomes. In a typical DNA-binding ZF module, there are twelve residues (numbered from -1 to -12) between the last zinc-coordinating cysteine and the first zinc-coordinating histidine. The established C2H2-ZF "recognition code" suggests that residues at positions -1, -4, and -7 recognize the 5', central, and 3' bases of a DNA base-pair triplet, respectively. Structural studies have highlighted that additional residues at positions -5 and -8 also play roles in specific DNA recognition. The presence of bulky and either charged or polar residues at these five positions determines specificity for given DNA bases: guanine is recognized by arginine, lysine, or histidine; adenine by asparagine or glutamine; thymine or 5-methylcytosine by glutamate; and unmodified cytosine by aspartate. This review discusses recent structural characterizations of C2H2-ZFs that add to our understanding of the principles underlying the C2H2-ZF recognition code.

Am J Med Genet A 2024:e63636.

Abstract
Biallelic pathogenic variations in the zinc finger protein 142 (ZNF142) gene are associated with neurodevelopmental disorder with impaired speech and hyperkinetic movements (NEDISHM). This disorder is characterized by developmental delay, intellectual disability, speech delay, and movement disorders such as dystonia, tremor, ataxia, and chorea. Here, we report a patient who exhibited common neurological features and rarely reported brain MRI findings. Exome sequencing identified a novel biallelic variant in ZNF142 (c.3528_3529delTG; p.C1176fs*5 (NM_001105537.4)). NEDISHM was first described by Khan et al. (2019) and has been reported in 39 patients to date. Furthermore, upon reviewing our in-house data covering 750 individuals, we identified three different pathogenic ZNF142 variants. It appears that the frequency of ZNF142 alleles is not as low as initially thought, suggesting that this gene should be included in new generation sequencing panels for similar clinical scenarios. Our goal is to compile and expand upon the clinical features observed in NEDISHM, providing novel insights and presenting a new variant to the literature. We also aim to demonstrate that ZNF142 pathogenic variants should be considered in neurodevelopmental diseases.

Novel missense variants cause intermediate phenotypes in the phenotypic spectrum of SLC5A6-related disorders. J Hum Genet 2024; 69:69-77. [PMID: 38012394 DOI: 10.1038/s10038-023-01206-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 11/05/2023] [Accepted: 11/05/2023] [Indexed: 11/29/2023]
Abstract
SLC5A6 encodes the sodium-dependent multivitamin transporter, a transmembrane protein that uptakes biotin, pantothenic acid, and lipoic acid. Biallelic SLC5A6 variants cause sodium-dependent multivitamin transporter deficiency (SMVTD) and childhood-onset biotin-responsive peripheral motor neuropathy (COMNB), which both respond well to replacement therapy with the above three nutrients. SMVTD usually presents with various symptoms in multiple organs, such as gastrointestinal hemorrhage, brain atrophy, and global developmental delay, at birth or in infancy. Without nutrient replacement therapy, SMVTD can be lethal in early childhood. COMNB is clinically milder and has a later onset than SMVTD, at approximately 10 years of age. COMNB symptoms are mostly limited to peripheral motor neuropathy. Here we report three patients from one Japanese family harboring novel compound heterozygous missense variants in SLC5A6, namely NM_021095.4:c.[221C>T];[642G>C] p.[(Ser74Phe)];[(Gln214His)]. Both variants were predicted to be deleterious through multiple lines of evidence, including amino acid conservation, in silico predictions of pathogenicity, and protein structure considerations. Drosophila analysis also showed c.221C>T to be pathogenic. All three patients had congenital brain cysts on neonatal cranial imaging, but no other morphological abnormalities. They also had a mild motor developmental delay that almost completely resolved despite no treatment. In terms of severity, their phenotypes were intermediate between SMVTD and COMNB. From these findings we propose a new SLC5A6-related disorder, spontaneously remitting developmental delay with brain cysts (SRDDBC) whose phenotypic severity is between that of SMVTD and COMNB. Further clinical and genetic evidence is needed to support our suggestion.

A deleterious frameshift insertion mutation in the ZNF142 gene leads to intellectual developmental disorder with impaired speech in three affected siblings: Clinical features and literature review. Mol Genet Genomic Med 2023; 11:e2261. [PMID: 37496384 PMCID: PMC10724506 DOI: 10.1002/mgg3.2261] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 06/28/2023] [Accepted: 07/19/2023] [Indexed: 07/28/2023] Open
Abstract
BACKGROUND ZNF142 gene is a protein-coding gene encoding Zinc Finger Protein 142. ZNF proteins are a vast group of cellular effectors with a wide range of functions such as signal transduction, transcriptional regulation, meiotic recombination, DNA repair, development, and cell migration. Mutations in the ZNF142 gene are related to neurodevelopmental disorder with impaired speech and hyperkinetic movements (NEDISHM). This study on a family with three affected siblings identified a pathogenic frameshift insertion variant. In addition, we conducted a review of the literature on previously reported ZNF142 gene variants and their clinical manifestations. MATERIALS AND METHODS Three affected siblings with severe intellectual developmental disabilities and speech impairments, their parents, and other sibs in the family were included. The patients were studied by the whole exome sequencing. Sanger sequencing, co-segregation analysis, and in silico analysis were carried out to verify candidate variant. The identified variant was interpreted based on the ACMG guideline. RESULTS We identified a frameshift insertion variant in the ZNF142 gene, NM_001379659.1: c.3755dup (NP_001366588.1:p.Arg1253ThrfsTer15), that was related to the clinical features of three patients. The identified variant was found to be pathogenic. CONCLUSION The current study findings expand the existing knowledge of the variant on the ZNF142 gene implicated in the neurodevelopmental disorder, intellectual disability, and impaired speech and it presents a detailed clinical feature associated with related conditions. The data have implications for genetic diagnosis and counseling in families with the same disorders.

Evolutionary Conserved Short Linear Motifs Provide Insights into the Cellular Response to Stress. Antioxidants (Basel) 2022; 12:antiox12010096.

Abstract
Short linear motifs (SLiMs) are evolutionarily conserved functional modules of proteins composed of 3 to 10 residues and involved in multiple cellular functions. Here, we performed a search for SLiMs that exert sequence similarity to two segments of alpha-fetoprotein (AFP), a major mammalian embryonic and cancer-associated protein. Biological activities of the peptides, LDSYQCT (AFP14-20) and EMTPVNPGV (GIP-9), have been previously confirmed under in vitro and in vivo conditions. In our study, we retrieved a vast array of proteins that contain SLiMs of interest from both prokaryotic and eukaryotic species, including viruses, bacteria, archaea, invertebrates, and vertebrates. Comprehensive Gene Ontology enrichment analysis showed that proteins from multiple functional classes, including enzymes, transcription factors, as well as those involved in signaling, cell cycle, and quality control, and ribosomal proteins were implicated in cellular adaptation to environmental stress conditions. These include response to oxidative and metabolic stress, hypoxia, DNA and RNA damage, protein degradation, as well as antimicrobial, antiviral, and immune response. Thus, our data enabled insights into the common functions of SLiMs evolutionary conserved across all taxonomic categories. These SLiMs can serve as important players in cellular adaptation to stress, which is crucial for cell functioning.
