The c.433G>A (p.D145N) alteration is located in exon 5 (coding exon 4) of the CCDC9 gene. This alteration results from a G to A substitution at nucleotide position 433, causing the aspartic acid (D) at amino acid position 145 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
