The c.1405A>G (p.S469G) alteration is located in exon 11 (coding exon 10) of the CCDC13 gene. This alteration results from a A to G substitution at nucleotide position 1405, causing the serine (S) at amino acid position 469 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
