The c.826G>A (p.V276M) alteration is located in exon 3 (coding exon 2) of the SLC45A3 gene. This alteration results from a G to A substitution at nucleotide position 826, causing the valine (V) at amino acid position 276 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
