The c.2017C>T (p.R673W) alteration is located in exon 18 (coding exon 18) of the PLA2G4F gene. This alteration results from a C to T substitution at nucleotide position 2017, causing the arginine (R) at amino acid position 673 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
