The c.865G>C (p.E289Q) alteration is located in exon 8 (coding exon 6) of the SLC22A31 gene. This alteration results from a G to C substitution at nucleotide position 865, causing the glutamic acid (E) at amino acid position 289 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
