The c.764A>G (p.Q255R) alteration is located in exon 8 (coding exon 8) of the GADL1 gene. This alteration results from a A to G substitution at nucleotide position 764, causing the glutamine (Q) at amino acid position 255 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
