Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.1538C>T (p.S513F) 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 1538, causing the serine (S) at amino acid position 513 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
