Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP5BS2BA1

This summary comes from the ClinGen Evidence Repository: The allele frequency of the p.Ala315Val variant in TCF4 is 0.1% in European (Non-Finnish) sub population in gnomAD, which is high enough to be classified as benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BA1). The p.Ala315Val variant is observed in at least 2 unaffected individuals (internal database) (BS2). The p.Ala315Val variant is found in a patient with an alternate molecular basis of disease (internal database) (BP5). In summary, the p.Ala315Val variant in TCF4 is classified as benign based on the ACMG/AMP criteria (BA1, BS2, BP5).

Genes affected
TCF4 (HGNC:11634): (transcription factor 4) This gene encodes transcription factor 4, a basic helix-loop-helix transcription factor. The encoded protein recognizes an Ephrussi-box ('E-box') binding site ('CANNTG') - a motif first identified in immunoglobulin enhancers. This gene is broadly expressed, and may play an important role in nervous system development. Defects in this gene are a cause of Pitt-Hopkins syndrome. In addition, an intronic CTG repeat normally numbering 10-37 repeat units can expand to >50 repeat units and cause Fuchs endothelial corneal dystrophy. Multiple alternatively spliced transcript variants that encode different proteins have been described. [provided by RefSeq, Jul 2016]

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -
