The c.216A>G (p.I72M) alteration is located in exon 3 (coding exon 2) of the SLC17A2 gene. This alteration results from a A to G substitution at nucleotide position 216, causing the isoleucine (I) at amino acid position 72 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
