Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.1424G>C (p.R475P) alteration is located in exon 6 (coding exon 6) of the UGT2A3 gene. This alteration results from a G to C substitution at nucleotide position 1424, causing the arginine (R) at amino acid position 475 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
