The c.1487A>G (p.H496R) 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 1487, causing the histidine (H) at amino acid position 496 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
