The c.1117C>G (p.L373V) alteration is located in exon 9 (coding exon 8) of the CCDC13 gene. This alteration results from a C to G substitution at nucleotide position 1117, causing the leucine (L) at amino acid position 373 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
