The c.388G>A (p.G130S) alteration is located in exon 2 (coding exon 2) of the CCDC85A gene. This alteration results from a G to A substitution at nucleotide position 388, causing the glycine (G) at amino acid position 130 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
