Summaries for Ceroid Lipofuscinosis, Neuronal, 4b, Autosomal Dominant

OMIM : 57 Neuronal ceroid lipofuscinosis-4B is an autosomal dominant neurodegenerative disorder characterized by onset of symptoms in adulthood. It belongs to a group of progressive neurodegenerative diseases characterized by accumulation of intracellular autofluorescent lipopigment storage material in the brain and other tissues. Several different forms have been described according to age of onset (see, e.g., CLN3, 204200). Individuals with the adult form, sometimes referred to as Kufs disease, develop psychiatric manifestations, seizures, cerebellar ataxia, and cognitive decline. Retinal degeneration is usually not present (summary by Benitez et al., 2011 and Velinov et al., 2012). For a general phenotypic description and a discussion of genetic heterogeneity of CLN, see CLN1 (256730). (162350)

MalaCards based summary : Ceroid Lipofuscinosis, Neuronal, 4b, Autosomal Dominant, also known as ceroid lipofuscinosis, neuronal, parry type, is related to neuronal ceroid lipofuscinosis and cln4 disease, and has symptoms including seizures, myoclonus and abnormality of extrapyramidal motor function. An important gene associated with Ceroid Lipofuscinosis, Neuronal, 4b, Autosomal Dominant is DNAJC5 (DnaJ Heat Shock Protein Family (Hsp40) Member C5). Affiliated tissues include brain, eye and cerebellum, and related phenotypes are depressivity and seizures

Disease Ontology : 12 A neuronal ceroid lipofuscinosis that is characterized by autosomal dominant inhetitance, onset of symptoms (psychiatric manifestations, seizures, cerebellar ataxia, and cognitive decline) in adulthood and has material basis in heterozygous mutation in the DNAJC5 gene (611203) on chromosome 20q13.

NIH Rare Diseases : 53 Autosomal dominant neuronal ceroid lipofuscinosis 4B is a form of adult neuronal ceroid lipofuscinosis, which is a rare condition that affects the nervous system. Signs and symptoms usually begin around age 30, but they can develop anytime between adolescence and late adulthood. Affected people generally experience behavioral abnormalities, dementia; difficulties with muscle coordination (ataxia); and involuntary movements such as tremors or tics. It can be caused by changes (mutations) in the DNAJC5 or CTSF gene and is inherited in an autosomal dominant manner. Treatment options are limited to therapies that can help relieve some of the symptoms.

UniProtKB/Swiss-Prot : 75 Ceroid lipofuscinosis, neuronal, 4B: An adult-onset neuronal ceroid lipofuscinosis. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. CLN4B has no visual involvement and is characterized by seizures and other neurologic symptoms.
