The c.1184G>C (p.R395P) alteration is located in exon 4 (coding exon 3) of the CCDC181 gene. This alteration results from a G to C substitution at nucleotide position 1184, causing the arginine (R) at amino acid position 395 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
