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. Cafer's Mood Stabilizers and Antiepileptics - Visualize to Memorize. CaferMed LLC, 2020. UGT1A4 UM *1a/*3b [Increased activity] Ultrarapid metabolizer: Risk of decreased serum levels. 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). 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. The patient is expected to have normal: enzyme activity. I've never had a histamine level drawn, that I know of (possibly done by allergist). My folate level has always been above register (> 25.2 ng/ml). Poor Metabolizer Breaks down medications very slowly. Jason Cafer UGT1A4 isoform is part of the UGT1A complex locus which displays alternative use of promoters, first exons and terminal exons. 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 Breaks down medications rapidly. 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 … The trend among fast metabolizers was quite the opposite. from psychiatrist: A woman with pronounced adverse effects CYP2D6*4/*4, poor metaboliser, no bioactivation of codeine. (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? The locus is defined by 13 first exons, which are alternatively spliced to 3 other common exons and 2 alternative terminal exons 5. 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.

Our findings therefore indicate that UGT1A4‐mediated metabolism is not a major contributor to interpatient variability in olanzapine levels.
