The c.1420A>G (p.S474G) alteration is located in exon 11 (coding exon 11) of the CCDC125 gene. This alteration results from a A to G substitution at nucleotide position 1420, causing the serine (S) at amino acid position 474 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
