The c.1007A>G (p.E336G) alteration is located in exon 8 (coding exon 6) of the SLC22A31 gene. This alteration results from a A to G substitution at nucleotide position 1007, causing the glutamic acid (E) at amino acid position 336 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
