Criteria Specification Information

Criteria Specifications for this VCEP
Evidence submitted by expert panel
Rett and Angelman-like Disorders VCEP
The p.Arg580Trp variant in TCF4 has been reported in at least 2 de novo occurrences (biological parentage unconfirmed) in individuals with Pitt-Hopkins syndrome (PMID 17436254, 22045651) (PM6_strong, PS4_supporting, PP4). The p.Arg580Trp in TCF4 is absent from gnomAD (PM2_supporting). The p.Arg580Trp variant occurs in the well-characterized basic Helix-Loop-Helix domain of TCF4 (PM1). In vitro binding assays have shown that this variant impacts protein function (PMID 22460224) (PS3_supporting). Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance on its own (PP3). In summary, the p.Arg580Trp variant in TCF4 is classified as Pathogenic for Pitt-Hopkins syndrome based on the ACMG/AMP criteria (PM6_strong, PM1, PM2_supporting, PS4_supporting, PP3, PP4).
