Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 12, 2021The c.1181T>C (p.F394S) alteration is located in exon 5 (coding exon 5) of the UGT2A3 gene. This alteration results from a T to C substitution at nucleotide position 1181, causing the phenylalanine (F) at amino acid position 394 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
