The c.1489G>A (p.A497T) alteration is located in exon 8 (coding exon 8) of the SLC2A13 gene. This alteration results from a G to A substitution at nucleotide position 1489, causing the alanine (A) at amino acid position 497 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
