Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2022The c.844T>C (p.C282R) alteration is located in exon 2 (coding exon 2) of the UGT2B4 gene. This alteration results from a T to C substitution at nucleotide position 844, causing the cysteine (C) at amino acid position 282 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
