CLN5 subtype of Batten Disease
Obtaining a definitive genetic diagnosis is an important first step in seeking appropriate care and treatment, learning about potential research or therapies that may become available, and preparing for the future. Patients and their families should consider discussing the implications of obtaining a diagnosis of CLN5 with their physician and a genetic counselor or other specialists who are familiar with the disease management of CLN5.
If you believe your child is showing signs or symptoms of CLN5, tests are available for a physician or other healthcare professional to order to confirm a diagnosis.
Many academic and commercial laboratories offer genetic blood testing. Testing for CLN5 may not be included in standard testing panels; however, upon request, a diagnostic genetic test including an Through this diagnostic test performed by a geneticist, the exome -- a sequence of all exons of protein coding genes in the human genome -- can be captured and analyzed with the intention of identifying a disease with a genetic component. for CLN5 can confirm a diagnosis. Your physician can help you navigate the process or refer you to a geneticist.
Neurogene has partnered with genetic testing company Invitae to offer a no-cost, 190+ gene Comprehensive Epilepsy Panel to any child under the age of 8 who has had an unprovoked seizure. For additional details:

A Clinician's Perspective on Diagnosis:
“CLN5 and CLN7 are two very rare forms of
Batten disease, both marked by regression of motor and language skills, as well as seizures, during childhood years. While signs and symptoms for both are similar to other types of Batten disease, these subtypes are not currently tested within a standard panel. If your child is experiencing motor and language regression, consider speaking to your healthcare provider about an Through this diagnostic test performed by a geneticist, the exome — a sequence of all exons of protein coding genes in the human genome — can be captured and analyzed with the intention of identifying a disease with a genetic component.. With a positive diagnosis, children may be eligible to participate in research that could help the community better understand Batten disease.”
