The c.973C>G (p.P325A) alteration is located in exon 8 (coding exon 8) of the APMAP gene. This alteration results from a C to G substitution at nucleotide position 973, causing the proline (P) at amino acid position 325 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
