Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BS2BA1BP4

This summary comes from the ClinGen Evidence Repository: The allele frequency of the p.Asn90Ser variant in TCF4 is 1.5% in Ashkenazi Jewish 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.Asn90Ser variant is observed in at least 2 unaffected individuals (internal database) (BS2). Computational analysis prediction tools suggest that the p.Asn90Ser variant does not have a deleterious impact; however this information does not predict clinical significance on its own (BP4). In summary, the p.Asn90Ser variant in TCF4 is classified as benign based on the ACMG/AMP criteria (BA1, BS2, BP4).

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]

ClinGen Rett and Angelman-like Disorders Variant Curation Expert Panel

Significance:Benign

Review Status:reviewed by expert panel

Collection Method:curation

The allele frequency of the p.Asn90Ser variant in TCF4 is 1.5% in Ashkenazi Jewish 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.Asn90Ser variant is observed in at least 2 unaffected individuals (internal database) (BS2). Computational analysis prediction tools suggest that the p.Asn90Ser variant does not have a deleterious impact; however this information does not predict clinical significance on its own (BP4). In summary, the p.Asn90Ser variant in TCF4 is classified as benign based on the ACMG/AMP criteria (BA1, BS2, BP4). -

Illumina Laboratory Services, Illumina

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Ambry Genetics

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
