Genes affected

GTF2E2 (HGNC:4651): (general transcription factor IIE subunit 2) The general transcription factor IIE (TFIIE) is part of the RNA polymerase II transcription initiation complex, recruiting TFIIH and being essential for promoter clearance by RNA polymerase II. TFIIE is a heterodimer (and sometimes heterotetramer) of alpha and beta subunits. The protein encoded by this gene represents the beta subunit of TFIIE. [provided by RefSeq, Jan 2017]

This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 250 of the GTF2E2 protein (p.Pro250Arg). This variant is present in population databases (rs773888848, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with GTF2E2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1409883). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GTF2E2 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
