Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BS2_SupportingBA1

This summary comes from the ClinGen Evidence Repository: The allele frequency of the p.Val168= variant in TCF4 is 0.057% 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.Val168= variant is observed in 1 unaffected individual (Baylor Genetics internal database) (BS2_supporting). In summary, p.Val168= variant in TCF4 is classified as benign based on the ACMG/AMP criteria (BA1, BS2_supporting).

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]
