Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.1399C>T (p.R467C) alteration is located in exon 6 (coding exon 6) of the UGT2A3 gene. This alteration results from a C to T substitution at nucleotide position 1399, causing the arginine (R) at amino acid position 467 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
