The c.959C>G (p.S320C) alteration is located in exon 9 (coding exon 9) of the PHTF2 gene. This alteration results from a C to G substitution at nucleotide position 959, causing the serine (S) at amino acid position 320 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
