Gene therapy [8] uses genetically modified viruses to deliver genes that can cure diseases in human cells.These viruses can deliver DNA or RNA genetic material to the targeted cells. Gene therapy is also used by inactivating mutated genes that are causing the disease using viruses. [9]
Gene therapy may be classified into two types by the type of cell it affects: somatic cell and germline gene therapy. In somatic cell gene therapy (SCGT), the therapeutic genes are transferred into any cell other than a gamete , germ cell , gametocyte , or undifferentiated stem cell .

The therapy known as Casgevy [9] works through editing a dysfunctional protein that interferes with creation of adult hemoglobin. This gene is known as the BCL11A, and when people have Beta thalassemia, their bodies do not make enough adult hemoglobin. Casgevy uses precise gene editing of stem cells, and reduces the activity of BCL11A.
The gene therapy will compete with Australia-based CSL Behring’s Hemgenix, a similar treatment that won FDA approval for hemophilia B in 2022. That drug has a similar list price of $3.5 million ...
Goldman Sachs downgraded Regenxbio Inc (NASDAQ:RGNX), citing gene therapy’s appeal for wet AMD and diabetic retinopathy is uncertain, as most patients are elderly and newer anti-VEGF treatments ...
In gene therapy a gene that is intended for delivery is packaged into a replication-deficient viral particle to form a viral vector. [29] Viruses used for gene therapy to date include retrovirus, adenovirus, adeno-associated virus and herpes simplex virus. However, there are drawbacks to using viruses to deliver genes into cells.
A vast majority of PDCD patients (80-88%) have a mutation on their PDHA1 gene. PDHA1 was shown to be a good candidate for gene therapy using an adeno associated virus (AAV2) to express the protein in vitro nearly 15 years ago; [22] however, research was discontinued. Since then, AAV technology, which is used as the delivery method to express ...
