Test ID: UGTFG    
UDP-Glucuronosyl Transferase 1A1 (UGT1A1), Full Gene Sequencing

Useful For Suggests clinical disorders or settings where the test may be helpful

Identifying individuals who are at increased risk of adverse drug reactions with drugs that are metabolized by UGT1A1, including irinotecan, atazanavir, nilotinib, pazopanib, and belinostat

 

Identifying individuals who are at risk of hyperbilirubinemia

 

Follow-up testing for individuals with a suspected UGT1A1 variant, who had negative TA repeat region testing

 

Establishing a diagnosis of Gilbert, Crigler-Najjar syndrome type I or type II

 

Establishing carrier status for Gilbert, Crigler-Najjar syndrome type I or type II

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

This is a full gene sequencing test for UGT1A1 that includes the TA repeat region of the promoter and all intron/exon boundaries. Results are interpreted for the purposes of UGT1A1 drug metabolism and hereditary hyperbilirubinemia syndromes (Gilbert syndrome and Crigler-Najjar syndrome).

Highlights

This test screens for UGT1A1 gene variants associated with increased risk of adverse drug reactions when taking UGT1A1-metabolized drugs. These drugs include irinotecan, atazanavir, nilotinib, pazopanib, and belinostat

 

This test screens for UGT1A1 gene variants associated with congenital hyperbilirubinemia conditions including Gilbert syndrome, Crigler-Najjar syndrome type I and type II
