The c.427G>A (p.G143R) alteration is located in exon 6 (coding exon 6) of the GLT1D1 gene. This alteration results from a G to A substitution at nucleotide position 427, causing the glycine (G) at amino acid position 143 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
