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 serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 289 of the GTF2E2 protein (p.Ser289Cys). This variant is present in population databases (rs751070215, gnomAD 0.005%). 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: 1450425). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
