The c.2596G>A (p.D866N) alteration is located in exon 22 (coding exon 21) of the CCDC178 gene. This alteration results from a G to A substitution at nucleotide position 2596, causing the aspartic acid (D) at amino acid position 866 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
