The c.325G>T (p.V109F) alteration is located in exon 2 (coding exon 2) of the PTGFRN gene. This alteration results from a G to T substitution at nucleotide position 325, causing the valine (V) at amino acid position 109 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
