The c.1876G>A (p.G626S) alteration is located in exon 20 (coding exon 20) of the ACAP3 gene. This alteration results from a G to A substitution at nucleotide position 1876, causing the glycine (G) at amino acid position 626 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
