The c.793T>C (p.S265P) alteration is located in exon 11 (coding exon 11) of the SLC38A6 gene. This alteration results from a T to C substitution at nucleotide position 793, causing the serine (S) at amino acid position 265 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
