The locus is defined by 13 first exons, which are alternatively spliced to 3 other common exons and 2 alternative terminal exons 5. The patient is expected to have normal: enzyme activity. UGT1A4 isoform is part of the UGT1A complex locus which displays alternative use of promoters, first exons and terminal exons. CaferMed LLC, 2020. CYP2D6*4/*4, poor metaboliser, no bioactivation of codeine. UGT1A4 UM *1a/*3b [Increased activity] Ultrarapid metabolizer: Risk of decreased serum levels. My folate level has always been above register (> 25.2 ng/ml). (UGT1A4*3) increased glucuronidation’’ from GP: A male with chronic ischaemic pain in legs; no pain relief despite very high doses of codeine – ultrarapid metabolism? Poor Metabolizer Breaks down medications very slowly. However, with respect to other drugs for which UGT1A4 has a dominant role in clearance, increased glucuronidation encoded by UGT1A4*3 might impact the risk for subtherapeutic drug exposure. Labs this year that may be of interest: (Genesight, others) I was found to be homozygous for 677T, CYP2C9 Poor Metabolizer, UGT1A4 Ultrarapid Metabolizer, COMT MET/MET, ADRA2A C/C. Ultrarapid Metabolizer Breaks down medications rapidly. from psychiatrist: A woman with pronounced adverse effects Possible adverse events associated with increased active metabolites A dose adjustment or alternate therapy may be considered U Be advised that there may be altered exposure to medications metabolized by UGT1A4 ABCB1 (rs2032583) A/G [Increased absorption/ May experience side ... + CYP3A4+ CYP2B6 + UGT1A4 CYP2D6 + CYP2C19 + CYP1A2 + CYP2C9 + CYP3A4+ CYP2B6 + UGT1A4 … I've never had a histamine level drawn, that I know of (possibly done by allergist). Cafer's Mood Stabilizers and Antiepileptics - Visualize to Memorize. Specifically UGT1A4 Was going over some old results and looking into things and I am an Ultrarapid Metabolizer for UGT1A4, which when I look up mentions rapid clearance of hormones, and specifically mentioned testosterone. Those who drank one to three cups of coffee daily had a significantly reduced risk of heart attacks – suggesting that for them coffee was protective.

Ultrarapid Metabolizer: UGT1A4 *1/*1: UGT1A4*1 allele enzyme activity: Normal UGT1A4*1 allele enzyme activity: Normal: This genotype is most consistent with the extensive (normal) metabolizer phenotype. By using the AmpliChip CYP450 Test, out of 182 subjects, we identified 8 poor metabolizer (PM), 17 intermediate metabolizer (IM), 151 extensive metabolizer (EM) and 3 ultrarapid metabolizer (UM). May not get enough medication at normal doses. Jason Cafer Our findings therefore indicate that UGT1A4‐mediated metabolism is not a major contributor to interpatient variability in olanzapine levels.
