The c.992A>G (p.H331R) alteration is located in exon 9 (coding exon 9) of the PHTF2 gene. This alteration results from a A to G substitution at nucleotide position 992, causing the histidine (H) at amino acid position 331 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
