The c.1342A>G (p.M448V) alteration is located in exon 15 (coding exon 14) of the SLC38A2 gene. This alteration results from a A to G substitution at nucleotide position 1342, causing the methionine (M) at amino acid position 448 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
