The lack of NGF signaling results in the improper development and function of sensory and sympathetic neurons. Patients with CIPA often suffer from repeated injuries, infections, and hyperthermia due to their inability to sense pain and regulate body temperature. Management focuses on preventing injuries, controlling infections, and providing supportive care, as there is no definitive cure for CIPA. We present several hypotheses for treating CIPA using stem cells and modern genetic techniques. One approach involves using induced pluripotent stem cells (iPSCs) to replace defective neurons. Another hypothesis suggests in vivo gene editing of neural progenitors to restore TrkA function. Additionally, mesenchymal stem cells (MSCs) genetically modified to overexpress NGF could provide trophic support.

CHD2 is a chromatin remodeler that was identified in 2013 as being a genetic cause for developmental and epileptic encephalopathies. Pathogenic changes in CHD2 can cause treatment-resistant epilepsy, intellectual and developmental delays, and autism, and some individuals experience neurodevelopmental regression. There are currently no targeted therapies available for CHD2-related disorders. Haploinsufficiency of CHD2 is a causative mechanism of disease for individuals with pathogenic variants (primarily truncating) in CHD2. Recently, identification of individuals with deletion of nearby gene CHASERR, a regulator of CHD2 gene expression, has established dosage sensitivity in CHD2 and solidified the CHASERR gene as a potential therapeutic target for CHD2 levels. Through collaboration with our community and our scientific advisory board, CCC has created a Roadmap to Cure CHD2 as our guide toward a targeted cure that can benefit our community, with steps including (1) identifying and defining patients, (2) developing models of CHD2, (3) studying models of CHD2, (4) testing therapies, (5) involving patients, and (6) reaching a cure. Despite some of the challenges inherent in CHD2 research including establishing animal and cellular models that recapitulate the CHD2 clinical phenotype, identifying measurable outcomes and reliable biomarkers, or testing emerging therapeutic approaches, CCC continues to engage with our community to support ongoing research that aligns with our priorities.

Following the birth of her two lovely twins, Amber Freed noticed how her son, Maxwell, missed motor development milestones and would often stare. Eventually, these signs led to a diagnosis of an <i>SLC6A1</i> variant. The <i>SLC6A1</i> gene is located on the short arm of chromosome 3 and the gene encodes for the gamma-aminobutyric acid (GABA) transporter 1 (GAT-1) protein. This transporter is responsible for the reuptake of the inhibitory neurotransmitter, GABA. The transporter usually removes GABA from the synapse space between two neurons, limiting over-excitability in the brain, which can lead to seizures and motor deficits as Amber noticed in her son, Maxwell. Amber realized that there were nearly no treatment options for her son's condition so she began forming connections with scientists and doctors. Initially, she flew to see Dr. Steven Gray, with whom she developed a research plan for a gene replacement therapy to treat the variant along with a design for a clinical trial. Not only this but they needed to raise four million dollars to fund these endeavors. Freed founded the <i>SLC6A1</i> Connect organization to raise money and awareness and put together a network of dedicated researchers and families. Since then, the organization has raised over two million dollars and grown to offer families a base of support. The organization even hosts a yearly symposium with families, scientists, and biotech or pharmaceutical companies worldwide. In addition, we detail how the organization now offers informational resources to families to help them understand the science behind the variant and ways to help their children such as registry links and genetic testing options. These endeavors have led the organization to collaborate with scientists based on institutions such as Vanderbilt University Medical Center, UT Southwestern Medical Center, the Cleveland Clinic, and many industrial pharmaceutical partners.</p>","PeriodicalId":75218,"journal":{"name":"Therapeutic advances in rare disease","volume":"5 ","pages":"26330040241283734"},"PeriodicalIF":0.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11459543/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142395861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
