The c.1603A>G (p.R535G) alteration is located in exon 2 (coding exon 2) of the DDN gene. This alteration results from a A to G substitution at nucleotide position 1603, causing the arginine (R) at amino acid position 535 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
