Genes affected

E2F6 (HGNC:3120): (E2F transcription factor 6) This gene encodes a member of a family of transcription factors that play a crucial role in the control of the cell cycle. The protein encoded by this gene lacks the transactivation and tumor suppressor protein association domains found in other family members, and contains a modular suppression domain that functions in the inhibition of transcription. It interacts in a complex with chromatin modifying factors. There are pseudogenes for this gene on chromosomes 22 and X. Alternative splicing results in multiple transcript variants.

Collection Method: clinical testing

The c.754G>A (p.G252R) alteration is located in exon 6 (coding exon 6) of the E2F6 gene. This alteration results from a G to A substitution at nucleotide position 754, causing the glycine (G) at amino acid position 252 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
