The c.310G>T (p.A104S) alteration is located in exon 4 (coding exon 2) of the SLC38A7 gene. This alteration results from a G to T substitution at nucleotide position 310, causing the alanine (A) at amino acid position 104 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
