The c.788G>A (p.R263Q) alteration is located in exon 8 (coding exon 6) of the SLC22A31 gene. This alteration results from a G to A substitution at nucleotide position 788, causing the arginine (R) at amino acid position 263 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
