Gene-Based Therapy Restores Cellular Development and Function in Brain Cells From People With Timothy Syndrome

            The article “Gene-Based Therapy Restores Cellular Development and Function in Brain Cells From People With Timothy Syndrome'' explains that there is a potential new therapy for Timothy syndrome, which is a life-threatening genetic disorder that affects many body styles, leading to cardiac, neurological, and psychiatric symptoms as well as leading to webbed fingers and toes. The particular treatment used is a cellular function; a 3D structure known as organoids could be a foundation for a new treatment. The specific gene that is examined is CACNA1Ct, which has a mutation that causes Timothy syndrome in small pieces of genetic material that can bind the gene products, which will promote the production of a protein not carrying the mutation, which is called antisense oligonucleotides (ASOs).In the lab, researchers applied antisense oligonucleotides to human brain tissue to restore normal cell function. It was transplanted into the brain at rates and was used from cells with people with Timothy syndrome. The gene mutation Timothy syndrome affects the exon 8A region of the CACNA1C gene, which is critical for cellular communication. Lastly, the findings in the lab will be used in a clinic to treat Timothy's syndrome effectively.
