Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.1193T>A (p.L398H) alteration is located in exon 5 (coding exon 5) of the UGT2A3 gene. This alteration results from a T to A substitution at nucleotide position 1193, causing the leucine (L) at amino acid position 398 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
