Genes affected
UGT2B17 (HGNC:12547): (UDP glucuronosyltransferase family 2 member B17) This gene encodes a member of the uridine diphosphoglucuronosyltransferase protein family. The encoded enzyme catalyzes the transfer of glucuronic acid from uridine diphosphoglucuronic acid to a diverse array of substrates including steroid hormones and lipid-soluble drugs. This process, known as glucuronidation, is an intermediate step in the metabolism of steroids. Copy number variation in this gene is associated with susceptibility to osteoporosis.[provided by RefSeq, Apr 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2023The c.1278G>C (p.L426F) alteration is located in exon 5 (coding exon 5) of the UGT2B17 gene. This alteration results from a G to C substitution at nucleotide position 1278, causing the leucine (L) at amino acid position 426 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
