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]

The c.1063T>C (p.Y355H) alteration is located in exon 4 (coding exon 4) of the UGT2B17 gene. This alteration results from a T to C substitution at nucleotide position 1063, causing the tyrosine (Y) at amino acid position 355 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
