Genetic polymorphisms in drug-metabolizing enzymes, transporters, and immune pathways contribute to interindividual variability in antiretroviral pharmacokinetics and toxicity. HLA-B *57:01 screening prior to abacavir initiation is an example of clinically implemented pharmacogenetics in high-income settings. Conversely, despite robust evidence linking UGT1A1 variants to atazanavir-associated hyperbilirubinaemia, routine UGT1A1 testing has not been widely adopted. We conducted a narrative review of genetic polymorphisms associated with the toxicity and pharmacokinetics of current antiretroviral therapy. We searched Pharmacogenomics Knowledgebase (PharmGKB®) for abacavir, tenofovir disoproxil fumarate, tenofovir alafenamide, lamivudine, emtricitabine, dolutegravir, elvitegravir, raltegravir, bictegravir, cabotegravir, atazanavir/ritonavir, darunavir/ritonavir, lopinavir/ritonavir, lenacapavir, rilpivirine and doravirine. We supplemented our review with targeted searches in PubMed®. We found that most pharmacogenetic associations for current antiretroviral drugs come from single studies and lack replication. Although UGT1A1 loss-of-function alleles increase dolutegravir and cabotegravir exposure, no association with toxicity has been shown. No relevant studies were identified for doravirine, lenacapavir or bictegravir. Actionable pharmacogenetic associations with antiretroviral drugs remain limited to abacavir. Future research should prioritize replicating pharmacogenetic associations across diverse populations and establishing clinical relevance.","PeriodicalId":20018,"journal":{"name":"Pharmacogenomics","volume":" ","pages":"145-158"},"PeriodicalIF":1.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13203070/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147875076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explores the emerging field of long non-coding RNAs (lncRNAs) in CLL, and their association with survival outcomes. We discuss how these pleiotropic transcripts act as master regulators of gene expression, orchestrating key cancer-related cellular processes, such as proliferation, apoptosis and communication with the tumor microenvironment. Furthermore, we examine how the aberrant expression of specific lncRNAs correlates with the established clinical and biological prognostic markers, response to treatment and survival of patients. By summarizing current findings, this review evaluates the potential of these regulatory transcripts as prognostic and/or predictive markers, as well as their prospects as innovative therapeutic targets. Understanding the mechanisms of action and functional roles of lncRNAs in pathobiology of CLL cells may contribute to refining risk stratification and developing personalized management strategies for patients with this complex leukemia.","PeriodicalId":20018,"journal":{"name":"Pharmacogenomics","volume":" ","pages":"159-177"},"PeriodicalIF":1.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13203066/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147949099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building on prior findings suggesting that SLC6A2 variation predicts venlafaxine response in LLD, we examined whether such genetic associations extend to older adults with chronic low back pain in the ADAPT study (Addressing Depression and Pain Together).Methods: Older adults with LLD and chronic low back pain received venlafaxine treatment over 20 weeks. The primary analysis focused on the SLC6A2 rs2242446 variant, whereas secondary analyses evaluated 37 variants across 14 candidate genes implicated in depression or pain. Outcomes included percentage improvement in PHQ-9 scores, remission, and time to remission.Results: Genotype data were available for 101 participants.

In secondary analyses, the serotonin 1A receptor gene (HTR1A) variant rs6295 emerged as the most consistent nominal genetic signal.Conclusion: Previously reported pharmacogenetic signal involving SLC6A2 did not extend to a more clinically complex population, whereas exploratory serotonergic variation showed a nominal association.
