The c.206G>A (p.G69E) alteration is located in exon 2 (coding exon 2) of the CCDC107 gene. This alteration results from a G to A substitution at nucleotide position 206, causing the glycine (G) at amino acid position 69 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
