The c.337C>G (p.H113D) alteration is located in exon 2 (coding exon 2) of the CCDC59 gene. This alteration results from a C to G substitution at nucleotide position 337, causing the histidine (H) at amino acid position 113 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
