The c.1435G>A (p.G479S) alteration is located in exon 10 (coding exon 10) of the SLC2A3 gene. This alteration results from a G to A substitution at nucleotide position 1435, causing the glycine (G) at amino acid position 479 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
