Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.1386C>A (p.F462L) alteration is located in exon 6 (coding exon 6) of the UGT2B4 gene. This alteration results from a C to A substitution at nucleotide position 1386, causing the phenylalanine (F) at amino acid position 462 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
