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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TCF4. . Gene score misZ 4.1035 (greater than the threshold 3.09). Trascript score misZ 4.5676 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, corneal dystrophy, Fuchs endothelial, 3, autosomal dominant non-syndromic intellectual disability, autism spectrum disorder, Fuchs' endothelial dystrophy, Pitt-Hopkins syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.3966272).

BP6

Variant 18-55275682-C-A is Benign according to our data. Variant chr18-55275682-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 380236.Status of the report is criteria_provided_single_submitter, 1 stars.
