The c.959G>T (p.R320M) alteration is located in exon 3 (coding exon 3) of the UGT2B4 gene. This alteration results from a G to T substitution at nucleotide position 959, causing the arginine (R) at amino acid position 320 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
