The c.2477C>G (p.P826R) alteration is located in exon 12 (coding exon 11) of the E2F7 gene. This alteration results from a C to G substitution at nucleotide position 2477, causing the proline (P) at amino acid position 826 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
