The c.745A>G (p.M249V) alteration is located in exon 6 (coding exon 6) of the SLC2A3 gene. This alteration results from a A to G substitution at nucleotide position 745, causing the methionine (M) at amino acid position 249 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
