The c.970C>T (p.L324F) alteration is located in exon 9 (coding exon 9) of the PHTF2 gene. This alteration results from a C to T substitution at nucleotide position 970, causing the leucine (L) at amino acid position 324 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
