Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.883T>C (p.F295L) alteration is located in exon 3 (coding exon 3) of the UGT2B4 gene. This alteration results from a T to C substitution at nucleotide position 883, causing the phenylalanine (F) at amino acid position 295 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
