SLC6A1 patient & organization perspective: founding of SLC6A1 connect, research, and ongoing efforts

This paper describes the founding of the SLC6A1 Connect organization, which offers resources to patients and families with SLC6A1 diagnoses while keeping current with a scientific overview of the disorder. 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 SLC6A1 variant. The SLC6A1 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 SLC6A1 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.
