The c.1580A>G (p.E527G) alteration is located in exon 6 (coding exon 6) of the UGT2A3 gene. This alteration results from a A to G substitution at nucleotide position 1580, causing the glutamic acid (E) at amino acid position 527 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
