Genes affected

UGT2B7 (HGNC:12554): (UDP glucuronosyltransferase family 2 member B7) The protein encoded by this gene belongs to the UDP-glycosyltransferase (UGT) family. UGTs serve a major role in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This protein is localized in the microsome membrane, and has unique specificity for 3,4-catechol estrogens and estriol, suggesting that it may play an important role in regulating the level and activity of these potent estrogen metabolites. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2017]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.036030054).
• BP6: Variant 4-69096657-T-C is Benign according to our data. Variant chr4-69096657-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 718812.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Homozygotes in GnomAdExome4 at 25 AR gene
