The c.1346G>A (p.G449E) alteration is located in exon 5 (coding exon 4) of the SLC45A3 gene. This alteration results from a G to A substitution at nucleotide position 1346, causing the glycine (G) at amino acid position 449 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
