The c.1726A>G (p.K576E) alteration is located in exon 13 (coding exon 13) of the PHTF1 gene. This alteration results from a A to G substitution at nucleotide position 1726, causing the lysine (K) at amino acid position 576 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
