Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the UGT2A3 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000024743.4. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: UDP-glucuronosyltransferases catalyze phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase water solubility and enhance excretion. They are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds (By similarity). {ECO:0000250}.
• Pathway: Retinol metabolism - Homo sapiens (human);Steroid hormone biosynthesis - Homo sapiens (human);Metabolism of xenobiotics by cytochrome P450 - Homo sapiens (human);Drug metabolism - other enzymes - Homo sapiens (human);Drug metabolism - cytochrome P450 - Homo sapiens (human);Porphyrin and chlorophyll metabolism - Homo sapiens (human);Chemical carcinogenesis - Homo sapiens (human);Ascorbate and aldarate metabolism - Homo sapiens (human);Pentose and glucuronate interconversions - Homo sapiens (human);Glucuronidation;Metapathway biotransformation Phase I and II;Glucuronidation;Phase II - Conjugation of compounds;Biological oxidations;Metabolism (Consensus)
