The c.699T>G (p.S233R) alteration is located in exon 7 (coding exon 6) of the SLC17A1 gene. This alteration results from a T to G substitution at nucleotide position 699, causing the serine (S) at amino acid position 233 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
