Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2021The c.1572G>C (p.K524N) alteration is located in exon 6 (coding exon 6) of the UGT2B4 gene. This alteration results from a G to C substitution at nucleotide position 1572, causing the lysine (K) at amino acid position 524 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
