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 GeneticsAug 02, 2021The c.1307C>T (p.S436L) alteration is located in exon 12 (coding exon 12) of the GTF2F1 gene. This alteration results from a C to T substitution at nucleotide position 1307, causing the serine (S) at amino acid position 436 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
