The c.328A>G (p.S110G) alteration is located in exon 3 (coding exon 3) of the PLA2G16 gene. This alteration results from a A to G substitution at nucleotide position 328, causing the serine (S) at amino acid position 110 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
