Genes affected

E2F3 (HGNC:3115): (E2F transcription factor 3) This gene encodes a member of a small family of transcription factors that function through binding of DP interaction partner proteins. The encoded protein recognizes a specific sequence motif in DNA and interacts directly with the retinoblastoma protein (pRB) to regulate the expression of genes involved in the cell cycle. Altered copy number and activity of this gene have been observed in a number of human cancers. There are pseudogenes for this gene on chromosomes 2 and 17. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2013]

Ambry Genetics

Nov 14, 2023

The c.18G>C (p.Q6H) alteration is located in exon 1 (coding exon 1) of the E2F3 gene. This alteration results from a G to C substitution at nucleotide position 18, causing the glutamine (Q) at amino acid position 6 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
