Genes affected
TCF12 (HGNC:11623): (transcription factor 12) The protein encoded by this gene is a member of the basic helix-loop-helix (bHLH) E-protein family that recognizes the consensus binding site (E-box) CANNTG. This encoded protein is expressed in many tissues, among them skeletal muscle, thymus, B- and T-cells, and may participate in regulating lineage-specific gene expression through the formation of heterodimers with other bHLH E-proteins. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitter | clinical testing | Seattle Children's Hospital Molecular Genetics Laboratory, Seattle Children's Hospital | Jun 22, 2021 | The c.722C>A pathogenic variant is located in exon 10 of 21 of the TCF12 gene and introduces a premature stop codon. It is predicted to cause a loss of protein function. The variant is absent from large population studies (Genome Aggregation Database v2.1.1). This specific nucleotide change has not been reported in the literature or patient databases; however, other TCF12 nonsense and frameshift variants at this amino acid position and across the protein have been reported as pathogenic in individuals with craniosynostosis (PMID: 23354436, PMID: 29215649, ClinVar Variation ID: 55913). - |
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Nov 29, 2021 | Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 23354436) - |
