The c.898A>G (p.N300D) alteration is located in exon 9 (coding exon 8) of the SLC17A1 gene. This alteration results from a A to G substitution at nucleotide position 898, causing the asparagine (N) at amino acid position 300 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
