The c.1246G>A (p.V416M) alteration is located in exon 10 (coding exon 9) of the SLC41A1 gene. This alteration results from a G to A substitution at nucleotide position 1246, causing the valine (V) at amino acid position 416 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
