The c.1304C>G (p.P435R) alteration is located in exon 5 (coding exon 4) of the SLC45A3 gene. This alteration results from a C to G substitution at nucleotide position 1304, causing the proline (P) at amino acid position 435 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
