The c.761C>A (p.A254D) alteration is located in exon 4 (coding exon 4) of the UGT3A2 gene. This alteration results from a C to A substitution at nucleotide position 761, causing the alanine (A) at amino acid position 254 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
