The c.1515G>T (p.L505F) alteration is located in exon 6 (coding exon 6) of the UGT2A3 gene. This alteration results from a G to T substitution at nucleotide position 1515, causing the leucine (L) at amino acid position 505 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
