The c.319A>G (p.K107E) 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 319, causing the lysine (K) at amino acid position 107 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
