The c.2339C>G (p.P780R) alteration is located in exon 22 (coding exon 22) of the EPS15L1 gene. This alteration results from a C to G substitution at nucleotide position 2339, causing the proline (P) at amino acid position 780 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
