Question Title: Batten disease (J NCL) carrier testingForum: Neurology Forum
| |
Interested in the neuro-degenerative genetic Spielmeyer-Vogt-Sjogren-Batten disease. Have learned that a test is available that will identify 73% of Batten disease (juvenile neuronal ceroid-lipofuscinosis) carriers by detecting a deletion of a gene on chromosome 16, CLN3. I understand that mutants of this gene are not detectable using the current test. What is the nature of the test? [immunoassay? electrophoretic? HPLC? ??] What are the requirements for the specimen? Post mortem testing possible? If an affected individual were tested, could the current test distinguish whether both copies of chromosome 16 were in the detectable 73%? Or would the test tell only that a detectable defect exists on at least one chromosome? Do I need to contact an organization or doctor in Finland for the latest information? If so, how? I am already aware of the Batten Disease Support and Research Association www.bdsra.org> Thank you for your service. :-) SS
