Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.989C>G (p.P330R) alteration is located in exon 3 (coding exon 3) of the UGT2A3 gene. This alteration results from a C to G substitution at nucleotide position 989, causing the proline (P) at amino acid position 330 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
