Dutch Pharmacogenetics Working Group (DPWG) Guideline for the Gene-Drug Interaction of CYP2C9, HLA-A, and HLA-B with Anti-epileptic Drugs

Dutch Pharmacogenetics Working Group Guideline for CYP2C9, HLA-A and HLA-B Gene-Drug Interactions with Antiepileptic Drugs Background Pharmacogenetics (PGx) studies how genetic variations affect individual drug responses, aiming to guide drug selection and dosing, optimize drug therapy, prevent adverse drug reactions, and achieve safer and more cos...

POT1 Tumour Predisposition: A Broader Spectrum of Associated Malignancies and Proposal for Additional Screening Program

POT1 Tumor Susceptibility Research: A Broader Spectrum of Related Malignancies and Recommendations for Additional Screening Plans Research Background POT1 (Protection of Telomeres Protein 1) is an important component of the Shelterin telomere-binding complex, responsible for regulating telomere length. Some pathogenic variants (PVs) of the POT1 gen...

Defining the Variant-Phenotype Correlation in Patients Affected by Noonan Syndrome with the RAF1:c.770C>T p.(Ser257Leu) Variant

Phenotypic Correlation Study of RAF1:c.770C>T p.(Ser257Leu) Variant in Noonan Syndrome Patients Academic Background Noonan syndrome (NS) is one of the most common RASopathies, primarily caused by the upregulation of RAS protein and mitogen-activated protein kinase (MAPK) signaling pathways. These disorders are characterized by facial dysmorphism, c...

Genome Sequencing Enables Diagnosis and Treatment of SLC5A6 Neuropathy

Diagnosis and Treatment of SLC5A6-Related Neuropathy: Insights from Genomic Sequencing Academic Background Genomics has always played an important role in the study and treatment of human diseases. The sodium-dependent multivitamin transporter (SMVT) encoded by the SLC5A6 gene is responsible for the uptake of biotin, pantothenic acid, and α-lipoic ...

Study on GABRA4 Gene Mutations and Neurological Phenotypes

New Scientific Research Reveals Association Between GABRA4 Gene and Neurological Phenotypes Research Background In recent years, significant progress has been made in the study of epilepsy and developmental disorder syndromes associated with single gene mutations. GABAA receptors (gamma-aminobutyric acid sub-type A receptors, GABAARs) are heterogen...

COQ7 Defect Causes Prenatal Onset of Mitochondrial CoQ10 Deficiency with Cardiomyopathy

Perinatal onset of mitochondrial CoQ10 deficiency due to COQ7 defect with cardiomyopathy and gastrointestinal obstruction Background Coenzyme Q10 (CoQ10) is a lipid-soluble molecule with antioxidant properties and a key component in electron transfer during oxidative phosphorylation in mitochondria. CoQ10 deficiency is a rare mitochondrial metaboli...

Loss-of-function variants in ERF are associated with a Noonan syndrome-like phenotype with or without craniosynostosis

Correlation between Erf Gene Loss-of-Function Variants and Noonan Syndrome-like Phenotype - With or Without Craniosynostosis Research Background Members of the ETS transcription factor family play a crucial role in RAS-MAPK signal transduction, regulating the expression of “early response” genes and other functionally related genes. Among them, ETS...

Validity of European-Centric Cardiometabolic Polygenic Scores in Multi-Ancestry Populations

Effectiveness of European-derived Cardiometabolic Polygenic Scores in Multi-ancestral Populations In recent years, Polygenic Scores (PGS) have received widespread attention as a tool for assessing individual genetic risk. However, most existing PGS are based on Genome-Wide Association Studies (GWAS) data from white European populations. This has le...

Somatic CAG Repeat Instability in Intermediate Alleles of the HTT Gene and its Potential Association with a Clinical Phenotype

Potential Association between Somatic CAG Repeat Instability in HTT Intermediate Alleles and Clinical Phenotype Research Background Huntington’s disease (HD) is a neurodegenerative disorder caused by the expansion of CAG trinucleotide repeats (≥36 CAG repeats) in the HTT gene. Intermediate alleles (IAs) with 27-35 CAG repeats are generally not cons...

Clinical Impact of Preemptive Pharmacogenomic Testing on Antiplatelet Therapy in a Real-World Setting

Clinical Impact of Pharmacogenomic Testing on Antiplatelet Therapy Background Pharmacogenomics (PGx) is changing the use of P2Y12 inhibitors (antiplatelet drugs), which are widely used in the treatment of acute coronary syndrome (ACS), neurovascular problems, and vascular diseases. Among them, clopidogrel is a commonly used P2Y12 inhibitor. This pr...
