Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.1074T>A (p.N358K) alteration is located in exon 4 (coding exon 4) of the UGT2A3 gene. This alteration results from a T to A substitution at nucleotide position 1074, causing the asparagine (N) at amino acid position 358 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
