The c.986C>G (p.A329G) alteration is located in exon 3 (coding exon 3) of the UGT2B4 gene. This alteration results from a C to G substitution at nucleotide position 986, causing the alanine (A) at amino acid position 329 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
