The c.776C>G (p.P259R) alteration is located in exon 8 (coding exon 8) of the CCZ1 gene. This alteration results from a C to G substitution at nucleotide position 776, causing the proline (P) at amino acid position 259 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
