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]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 8-30580265-G-A is Benign according to our data. Variant chr8-30580265-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2991583.Status of the report is criteria_provided_single_submitter, 1 stars.
