Genes affected
GTF2F1 (HGNC:4652): (general transcription factor IIF subunit 1) Enables several functions, including RNA polymerase II general transcription initiation factor activity; phosphatase activator activity; and promoter-specific chromatin binding activity. Involved in several processes, including positive regulation of transcription by RNA polymerase II; response to virus; and transcription initiation from RNA polymerase II promoter. Located in cell junction and nucleoplasm. Part of transcription factor TFIID complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 06, 2023The c.976G>A (p.E326K) alteration is located in exon 9 (coding exon 9) of the GTF2F1 gene. This alteration results from a G to A substitution at nucleotide position 976, causing the glutamic acid (E) at amino acid position 326 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
