Collection Method: clinical testing

The c.494C>G (p.P165R) alteration is located in exon 2 (coding exon 2) of the DDN gene. This alteration results from a C to G substitution at nucleotide position 494, causing the proline (P) at amino acid position 165 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
