Pharmacogenomics is the integration of genomics and pharmacology to optimize drug response and reduce side effects. In terms of personalized or individualized medicine, PGx is defined as the identification and analysis of specific genetic variants associated with particular drug treatments for each patient. Under a precision public health (PPH) approach, population-level data are analyzed to generate public health strategies. The objective of this study was to conduct a scoping review of technological tools, examining their evolution, the predominance of high-income countries in their development, and the gaps and needs for genomic data and advances in low- and middle-income countries (LMICs). This review was conducted in accordance with the ScPRISMA guidelines. A search was conducted in PubMed, Web of Science and Embase until January 2024. A total of 40 documents were selected, which revealed the continuous evolution and progressive development of pharmacogenomic tools. The technological tools developed come from high-income countries, particularly the United States, Canada, China, and several European nations, where international collaboration has been essential to maintain and expand these tools, which have evolved to keep pace with the rapid generation of genomic data. This trend shows a scarce development of technological tools for public health precision in LMICs, which evidences the need to increase investment in genomic research infrastructure in this aspect and in the development of capacities to guarantee global accessibility and boost PPH for all populations.

Genetic polymorphisms in the genes encoding enzymes and proteins in drug metabolism, transport, and response can significantly impact enzymatic activity and overall pharmacokinetics and pharmacodynamics, leading to inter-individual and inter-population differences in drug efficacy and safety. The prevalence of pharmacogenomic variants often differs among populations due to unique evolutionary and demographic factors. By studying the genetic variation within 100 pharmacogenes in the Kinh Vietnamese population, a relatively underexplored group in pharmacogenomic research, we aim to provide insights into the population-specific pharmacogenomic landscape.

In addition, a nomogram model to predict the prognosis of breast cancer patients was constructed in this study.

Joubert syndrome (JS) is an infrequent congenital neurodevelopmental ciliopathy, typically identified in children around the average age of 33 months. This disorder is characterized by developmental delay, cognitive impairment, and infantile hypotonia that may evolve into ataxia. Mutations in results in Joubert syndrome with a variety of phenotypes. Here, we identified a child who presented with Joubert syndrome exhibiting orofaciodigital spectrum anomalies, polydactyly, and retinitis pigmentosa. Whole exome sequencing and Sanger sequencing revealed a splicing mutation (NM_003611.2, c.2387+1G>A) in the gene of the patient and his mother. mRNA sequencing further confirmed this mutation. However, since the patient is homozygous and the mother is heterozygous, only the patient has the phenotype and the mother is normal. This mutation can lead to the loss of sixth coiled-coil domains of OFD1 protein, which further disrupt the ciliary signaling pathway and Hedgehog signaling pathway. This study presents a new case of JS and expands the mutant spectrum of , but also enhances our understanding of the mechanism by which is associated with ciliosis.

KRAS mutations are typically mutually exclusive in non-small cell lung cancer (NSCLC), with the G12C mutation being the most common subtype. The coexistence of KRAS and EGFR mutations is exceedingly rare and is typically emerges as a secondary event following acquired resistance to EGFR-targeted therapies. We presented a case of a newly diagnosed NSCLC patient harboring concurrent EGFR L858R and KRAS G12A mutations.

We aimed to determine the prevalence of interactions between PGx drugs metabolized by CYP2C9, CYP2C19, and CYP2D6 and drugs that act as inhibitors or inducers of those enzymes in the Swiss population.

Ulcerative colitis represents an inflammatory bowel disease with multiple contributing factors, marked by persistent inflammation of the colonic mucosa, which can lead to a reduced life expectancy and an elevated likelihood of requiring colectomy as well as developing colorectal cancer. Despite impacting roughly 5 million individuals worldwide, the intricate mechanisms underlying ulcerative colitis are still inadequately defined, hindering the development of effective treatments. Extra-intestinal complications, including enteropathic arthritis, are also addressed in the context of disease burden and management. This review explores the multifaceted pathogenesis of ulcerative colitis, emphasizing critical factors such as abnormalities in the epithelial barrier, irregular immune responses, the release of inflammatory mediators, and alterations in gut microbiota composition. We also underscore recent advancements in diagnostic biomarkers that improve the accuracy of disease detection and monitoring. Conventional medicinal strategies are reviewed alongside the emergence of biological therapies, notably those that target tumor necrosis factor (TNF), interleukins, and integrins, which have significantly altered management approaches. Established therapies (eg, 5-aminosalicylic acid, corticosteroids) and emerging agents (eg, JAK inhibitors, S1P modulators) are clearly delineated. Combination strategies-such as dual biologic regimens or JAK inhibitors combined with anti-integrin agents-are also discussed in dedicated subsections. We discuss novel therapies that utilize small molecule targeting, particularly those that inhibit Janus kinase (JAK) and modulate sphingosine-1-phosphate (S1P) receptors, presenting promising avenues for treatment. Additionally, fecal microbiota transplantation (FMT) is evaluated as a therapeutic option, as it shows promise in restoring microbial balance. Collectively, these advances underscore the pivotal roles of immune dysregulation, biologic therapies, and microbiota modulation in reshaping precision management of ulcerative colitis. This synthesis of current knowledge underscores the necessity for continued research to refine therapeutic strategies and improve patient outcomes in ulcerative colitis.

The purpose of this study was to investigate the association of SNPs in miRNA genes targeting the PI3K/AKT/GSK3β pathway with T2DM.

This paper systematically reviews recent advances in clopidogrel clinical applications to optimize therapeutic precision and medication safety. Using a literature review methodology, we elucidate clopidogrel's pharmacokinetic properties and pharmacodynamic mechanisms, while evaluating its clinical efficacy and adverse reactions in disease management. Recent studies have emphasized the key role of genetic polymorphisms in regulating the efficacy and safety of clopidogrel. Polymorphisms in the gene have a significant effect on the metabolism of clopidogrel, with loss-of-function (LOF) alleles () reducing the production of active metabolites, leading to elevated platelet reactivity and increasing the risk of major adverse cardiovascular events (MACE), particularly in the Asian populations, where the prevalence of LoF alleles is as high as 29-35%. In contrast, the gain-of-function allele results in a reduced risk of cardiovascular events but increases the risk of bleeding. This article summarizes the latest research progress and monitoring methods of clopidogrel, and suggests that clinics should combine genotyping and platelet function testing with monitoring of blood levels to optimize treatment and provide data reference for clinical administration of clopidogrel.

Pharmacogenomics holds significant promise in improving the efficacy and safety of chemotherapy for childhood cancers. However, the field remains underexplored in Africa, where high genetic diversity and substantial disease burdens, including cancers, create unique challenges. This review investigates the current state of pharmacogenomics research in childhood cancer chemotherapies across Africa, focusing on genetic variations influencing chemotherapy efficacy and adverse drug reactions. It also highlights critical gaps, such as limited infrastructure and insufficient healthcare worker knowledge, and emphasizes the importance of capacity-building initiatives in the region.

Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disease that is characterized by progressive proximal muscle weakness and pseudohypertrophy. Currently, genetic diagnosis of DMD relies largely on multiplex ligation-dependent probe analysis (MLPA) and Sanger sequencing to identify pathogenic mutations. This study aimed to confirm the genetic etiology of a boy presenting with clinical manifestations that are highly indicative of DMD. A 14-year-old boy with heart failure and extreme muscle weakness along with his family members was recruited for this study. DNA from each participant was isolated from peripheral blood samples. We used MLPA to detect the deletion or duplication mutations of the gene and Sanger sequencing to verify the missing region of the exon in the proband. Furthermore, the functional role of the mutation was assessed using bioinformatics. We found that the proband carried a small deletion in the gene (c.6808_6811delTTAA). The deletion of those four nucleotides resulted in a frameshift mutation and a premature nonsense codon, which resulted in a truncated dystrophin that lost its most critical function and underwent post-transcriptional degradation. Our study demonstrated that MLPA, in combination with Sanger sequencing, is a reliable and practical approach for the genetic diagnosis of DMD, which is a significant step towards developing personalized therapy.
