The c.517C>G (p.P173A) alteration is located in exon 2 (coding exon 2) of the NXPH2 gene. This alteration results from a C to G substitution at nucleotide position 517, causing the proline (P) at amino acid position 173 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
