The c.520T>G (p.F174V) alteration is located in exon 6 (coding exon 5) of the PLSCR4 gene. This alteration results from a T to G substitution at nucleotide position 520, causing the phenylalanine (F) at amino acid position 174 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
