BACKGROUND: Kufs disease type B (also termed CLN13), an adult-onset form of neuronal ceroid lipofuscinosis (NCL), is genetically heterogeneous and challenging to diagnose. Recently, mutations in cathepsin-F have been identified as the causative gene for autosomal recessive Kufs disease type B. RESULTS: Here, we report a sporadic case of Kufs disease type B with novel compound heterozygous mutations, a novel missense mutation c.977G>T (p.C326F) and a novel nonsense mutation c.416C>A (p.S139X), in the cathepsin-F gene. The magnetic resonance imaging findings were consistent with those demonstrated in adult neuronal ceroid lipofuscinosis: diffuse cortical atrophy, mild hyperintensity and reduction of the deep white matter on T2-weighted images. A skin biopsy was negative for abnormalities. CONCLUSIONS: Altogether, our findings broaden the mutation database in relation to the neuronal ceroid lipofuscinosis, and the clinical diagnosis of Kufs disease type B was confirmed.
