Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2023The c.1034A>G (p.N345S) alteration is located in exon 5 (coding exon 5) of the UGT3A1 gene. This alteration results from a A to G substitution at nucleotide position 1034, causing the asparagine (N) at amino acid position 345 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
