The c.2275G>A (p.G759S) alteration is located in exon 23 (coding exon 23) of the ACAP3 gene. This alteration results from a G to A substitution at nucleotide position 2275, causing the glycine (G) at amino acid position 759 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
