An ex-vivo lentiviral vector (LVV) gene therapy, Zynteglo’s every dose is made by genetically modifying the bone marrow stem cells of the patient to produce functional beta-globin.
A trio of bioengineering scientists at Ecole Polytechnique Fédérale de Lausanne has found age and gender differences in gene expression related to the circadian clock. For their paper published in the journal Science, Lorenzo Talamanca, Cédric Gobet and Felix Naef analyzed data obtained for the Genotype-Tissue Expression project.
The treatment is indicated for CF patients who are homozygous for the F508del mutation (F/F genotype) in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. It enrolled 46 children aged one to under two years with the F/F genotype. According to the findings, Orkambi was found to be well tolerated.
Awareness of rare diseases is growing, and with a better understanding of the pathophysiology of many rare diseases, innovative treatment options are emerging, like gene therapies that can treat the root cause of rare genetic diseases and potentially provide long-term symptom relief, or even a definitive cure.
National Institutes of Health researchers have published an assessment of 13 studies that took a genotype-first approach to patient care. This approach contrasts with the typical phenotype-first approach to clinical research, which starts with clinical findings. The study was published in the American Journal of Human Genetics.

In some cases, the gene associated with a patient’s condition may not yet be discovered or included on the test ordered and the interpretation of genetic variants may change over time as new information is uncovered. single gene testing vs comprehensive panel), the reportable range (e.g.,
The test is based on the detection of actionable genes – genes with known driver mutations that can be targeted by an approved therapy (or investigational therapies in clinical trials). The panel of genes in the test only include known NSCLC-associated genes, making the test specific to the disease. Personalized Approach.
Using cervical or self-collected vaginal specimens, the test works with the BD Viper LT and BD COR systems to detect individual genotypes, such as HPV 16, 18 and 31, and grouped results for other types. Companion diagnostic for Pfizers hemophilia B gene therapy Beqvez (idanacogene elaparvovec-dzkt).
From a total of 30 single-nucleotide polymorphisms (SNPs) in genes previously identified as being associated with blood pressure, many had a relatively neutral effect on the risk of coronary artery disease. Figure 2: Using drug-target MR to validate sympathetic nervous system genes involved in heart failure.
Therefore, there is also a significant need for new therapies that target the underlying cause of CFD that may offer a cure for patients living with severe disease, or for patients with genotypes such as dysfibrinogenemia and hypodysfibrinogenemia, who are often ineligible for treatment with HFCs.
In patients with T790M mutant NSCLC receiving osimertinib, 63% experienced loss of T790M at progression, commonly linked to histological transdifferentiation, KRAS mutations, or gene fusions. In the same study, those with T790M loss had a shorter treatment duration (6.1 months vs. 15.2 months, p = 0.01).
How many genes need to be scanned in order to determine the presence of a genetic disease? HS: Due to the heterogeneity of the rare disease population, there are many relevant gene lists, and the genomic data analysis of these patients covers almost 2,000 different genetic targets.
Pharma has used this to begin creating targeted treatments, such as gene therapies , which are able to hone in on gene mutations that cause health issues and eradicate or replace the faulty gene. Scientists are able to study the aggregated, de-identified genetics of these individuals.
The study by a team at the Universities of East Anglia and Edinburgh shows that HRT use is associated with better memory, cognition, and larger brain volumes in later life among women carrying the APOE4 gene, a well-established risk factor for Alzheimer’s.
The human history study, which is being funded by the foundation and its supporters, will feed into gene reviews, an international point-of-source for inherited disorders. The team hopes that this study’s scope will also shed light on the gene’s impact on the women who carry it in addition to an elaborative genotype-phenotype correlation.
Pharmacogenomics, the understanding of how genes impact an individual’s response to medications, provides a potential outlet to better optimised therapies. The program is aiming to genotype roughly 150,000 participants over the next few years to demonstrate the impact personalised testing can have on a large scale.
ONWARD is investigating Adial’s lead drug candidate, AD04, as a therapeutic agent for the treatment of Alcohol Use Disorder (AUD) in persons with certain target genotypes related to the serotonin transporter and receptor genes. Key ONWARD highlights include:
All 25 planned investigative sites are active.
It recommends the National Library of Medicine, which has already published “considerable information” on resistance genes, genome sequences, antimicrobial susceptibility data, and bacterial genomes, establish an open-source, unified AMR database.
MoCD Type A is an autosomal recessive, inborn error of metabolism caused by mutations in the molybdenum cofactor synthesis 1 gene. In the analysis involving 31 patients, 13 were treated with Nulibry and compared to 18 genotype-matched untreated patients from the history control group. What is Molybdenum Cofactor Deficiency Type A?
According to a study, around 20,000 genes are present in the human body, all of which interact with the nutrients in the food, either directly or indirectly. For instance, carbohydrates increase the expression of genes responsible for the synthesis of enzymes and transporters involved in their metabolism.
Hybridization Tests – These tests utilize complementary DNA or RNA probes to detect and quantify specific genetic targets, enabling the identification of pathogens, genetic variations, and gene expression patterns. Such test can be used for gene expression profiling, genotyping and detecting chromosomal abnormalities.
In some areas, say Alzheimer’s disease, we have growing collections of imaging, gene, cerebrospinal fluid (CSF) and blood markers to follow and look at target engagement of our drugs,” says James Vornov, MD, PhD, Vice President of the Medical Department at Medpace.
such as the integrase gene and assay validation recommendations. The recommended specimen types for HIV drug resistance genotyping are plasma or dried blood spots. Dried blood spots should be used for HIV drug resistance surveys in which plasma cannot. be handled as per WHO recommendations.
The Chinese biopharmaceutical industry is growing in leaps and bounds, but there is still a huge unmet need when it comes to getting patients access to the breakthrough therapeutic modalities and platforms like RNAi, cell and gene therapy and others.
