The c.595G>A (p.V199M) alteration is located in exon 7 (coding exon 7) of the GLT1D1 gene. This alteration results from a G to A substitution at nucleotide position 595, causing the valine (V) at amino acid position 199 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
