The c.2120A>G (p.Y707C) alteration is located in exon 18 (coding exon 18) of the PLA2G4F gene. This alteration results from a A to G substitution at nucleotide position 2120, causing the tyrosine (Y) at amino acid position 707 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
