The c.52G>A (p.G18R) alteration is located in exon 1 (coding exon 1) of the ATP2C2 gene. This alteration results from a G to A substitution at nucleotide position 52, causing the glycine (G) at amino acid position 18 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
