Collection Method: clinical testing

The c.961G>A (p.V321M) alteration is located in exon 9 (coding exon 7) of the SLC38A7 gene. This alteration results from a G to A substitution at nucleotide position 961, causing the valine (V) at amino acid position 321 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
