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]

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). This variant has not been reported in the literature in individuals affected with GTF2E2-related conditions. This variant is present in population databases (rs764969255, gnomAD 0.003%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 230 of the GTF2E2 protein (p.Glu230Lys). -
