Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 15, 2023The c.1429C>T (p.R477W) alteration is located in exon 6 (coding exon 6) of the UGT2B4 gene. This alteration results from a C to T substitution at nucleotide position 1429, causing the arginine (R) at amino acid position 477 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
