The c.526T>C (p.C176R) alteration is located in exon 7 (coding exon 7) of the CCDC12 gene. This alteration results from a T to C substitution at nucleotide position 526, causing the cysteine (C) at amino acid position 176 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
