Konstantinos Varvagiannis gene: ZNF142 was added gene: ZNF142 was added to Genetic epilepsy syndromes. Sources: Literature Mode of inheritance for gene: ZNF142 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: ZNF142 were set to 31036918 Phenotypes for gene: ZNF142 were set to Global developmental delay; Intellectual disability; Seizures; Tremor; Dystonia Penetrance for gene: ZNF142 were set to Incomplete Review for gene: ZNF142 was set to AMBER Added comment: Khan et al. (2019 - PMID: 31036918) describe the phenotype of 7 females from 4 families, harboring biallelic likely pathogenic ZNF142 variants. Overlapping features included cognitive impairment (ID in 6/7 from 3 families, borderline intellectual functioning was reported one occasion), speech impairement and motor impairment (7/7), and variably penetrant seizures (5/7), tremor (4/7) and dystonia (3/7). Most individuals (5/7) had experienced at least one episode of seizures (tonic-clonic) though seizures were recurrent in 3 sibs. Other disorders with ID (eg. Angelman syndrome, Rett syndrome, chromosomal disorders) or movement disorders as a feature were previously ruled out for many subjects. 6 individuals were homozygous or compound heterozygous for LoF (stopgain or frameshift) variants. One individual harbored 2 missense SNVs in the compound heterozygous state. Variants reported include (NM_001105537.2): c. 817_818delAA (p.Lys273Glufs*32), c.1292delG (p.Cys431Leufs*11), c.3175C>T (p.Arg1059*), c.4183delC (p.Leu1395*), c.3698G>T (p.Cys1233Phe), c.4498C>T (p.Arg1500Trp) with the LoF variants predicted to result in NMD. Expression or functional studies were not carried out. ZNF142 encodes a C2H2 domain-containing transcription factor. Mutations in other zinc finger proteins (ZNF/zfp) have been reported in several neurodevelopmental disorders impacting the CNS (eg. ZBTB20 and ZBTB11 heterozygous and biallelic mutations, respectively) and/or presenting with movement disorders among their manifestations (eg. YY1). As the authors comment, homozygous ablation of the orthologous (Zfp142) locus in mice results in behavioral and neurological phenotypes [MGI ref.ID: J:211773 cited - http://www.informatics.jax.org/marker/reference/J:211773 (though Zfp142 or its locus do not seem to appear in the list)]. ZNF142 is not - at least commonly - included in gene panels for ID offered by diagnostic laboratories. It is not associated with any phenotype in OMIM, nor in G2P. As a result, this gene can be considered for inclusion in the current panel as probably as amber (seizures in 5/7 individuals, though many had a single occurrence) or green. Sources: Literature |
