The c.1255A>G (p.T419A) alteration is located in exon 5 (coding exon 5) of the UGT2B4 gene. This alteration results from a A to G substitution at nucleotide position 1255, causing the threonine (T) at amino acid position 419 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
