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]

The c.1459G>A (p.E487K) alteration is located in exon 13 (coding exon 13) of the GTF2F1 gene. This alteration results from a G to A substitution at nucleotide position 1459, causing the glutamic acid (E) at amino acid position 487 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
