Abstract

Schizophrenia is a severe mental disorder that affects how a person thinks, feels, and behaves. Antipsychotic drugs are the treatment of choice for patients with schizophrenia. Clozapine is an atypical antipsychotic with unique efficacy in treatment-resistant schizophrenia. However, genetic variations in CYP1A2 can influence the differences in the activity of this enzyme, which in turn can affect the metabolism of clozapine and the response to treatment. This review aims to examine the impact of CYP1A2 genetic variations on clozapine metabolism in patients with schizophrenia. This review is prepared using the narrative literature review method, literature search was conducted through PubMed over the past ten years (2014-2024) using relevant keywords. The findings indicate that CYP1A2 genetic variations *1F is an ultrarapid metabolizer whose activity is strengthened by the presence of cigarettes, while *1C and *1D shows a decrease in CYP1A2 enzyme metabolism. This review underscores the importance of considering genetic factors, particularly CYP1A2, in tailoring treatment plans for schizophrenia patients

Abstract

Reliable clinical diagnosis of Single Nucleotide Polymorphisms (SNPs) is necessary for personalizing tamoxifen medication according to CYP2D6*10 genetic variations. Our research aimed to create a recombinant plasmid for external control material with a molecular size of 3812 bp. The recombinant plasmid was achieved by cloning an 838 bp gene insert of CYP2D6*10 rs1065852 into a 2974 bp pJET1.2 plasmid into Escherichia coli DH10B and selection on ampicillin agar medium. Isolated E. coli recombinants provided the plasmid molecules for analysis. Bi-directional sequencing and Real-Time PCR confirmed the presence of wild-type and mutant rs1065852 DNA fragments in the plasmid, namely homozygote CC and TT. The conclusion is that we have successfully introduced a novel recombinant plasmid developed by cloning the SNP rs1065852, which carries the 100C>T mutation, using pJET 1.2/blunt system, which could significantly enhance the accuracy of clinical SNP diagnostics for personalized medicine in breast cancer treatment.
