The c.1789C>T (p.R597C) alteration is located in exon 13 (coding exon 13) of the PHTF1 gene. This alteration results from a C to T substitution at nucleotide position 1789, causing the arginine (R) at amino acid position 597 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
