Organ System | Phenotype Count | Example Features |
|---|---|---|
Brain and nerves | 6 | Brain shrinkage (cerebral atrophy), Delayed speech and language development, Loss of previously acquired skills (developmental regression) |
CLN8 encodes CLN8 transmembrane ER and ERGIC protein (286 aa). Could play a role in cell proliferation during neuronal differentiation and in protection against cell death
Neuronal ceroid lipofuscinosis 8 is associated with mutations in the CLN8 gene on chromosome 8.
CLN8 is classified as a druggable target with score 7.5.
Genetic testing for CLN8 is available. Testing is considered confirmatory for diagnosis.
