Summaries for Ceroid Lipofuscinosis, Neuronal, 7

NIH Rare Diseases : 49 Neuronal ceroid lipofuscinosis 7 (CLN7-NCL) is a rare condition that affects the nervous system. Signs and symptoms of the condition generally develop in early childhood (average age 5 years) and may include loss of muscle coordination (ataxia), seizures that do not respond to medications, muscle twitches (myoclonus), visual impairment, and developmental regression (the loss of previously acquired skills). CLN7-NCL is caused by changes (mutations) in the MFSD8 gene and is inherited in an autosomal recessive manner. Treatment options are limited to therapies that can help relieve some of the symptoms. Last updated: 9/2/2015

MalaCards based summary : Ceroid Lipofuscinosis, Neuronal, 7, also known as cln7, is related to ceroid lipofuscinosis, neuronal, 1 and neuronal ceroid lipofuscinosis, and has symptoms including ataxia, eeg abnormality and sleep disturbance. An important gene associated with Ceroid Lipofuscinosis, Neuronal, 7 is MFSD8 (Major Facilitator Superfamily Domain Containing 8), and among its related pathways/superpathways is Lysosome. Related phenotypes are behavior/neurological and nervous system

OMIM : 53 The neuronal ceroid lipofuscinoses (NCL, or CLN) are a clinically and genetically heterogeneous group of neurodegenerative disorders characterized by the intracellular accumulation of autofluorescent lipopigment storage material in different patterns ultrastructurally (summary by Mole et al., 2005). For a general phenotypic description and a discussion of genetic heterogeneity of CLN, see CLN1 (256730). (610951)

UniProtKB/Swiss-Prot : 71 Ceroid lipofuscinosis, neuronal, 7: A form of neuronal ceroid lipofuscinosis with onset in early childhood. 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. The lipopigment patterns observed most often in neuronal ceroid lipofuscinosis type 7 comprise mixed combinations of granular, curvilinear, fingerprint, and rectilinear profiles.

Genetics Home Reference : 24 CLN7 disease is an inherited disorder that primarily affects the nervous system. The signs and symptoms of this condition typically begin between ages 2 and 7. The initial features usually include recurrent seizures (epilepsy) and the loss of previously acquired skills (developmental regression). Affected children also develop muscle twitches (myoclonus), difficulty coordinating movements (ataxia), speech impairment, and vision loss. Mental functioning and motor skills (such as sitting and walking) decline with age. Individuals with CLN7 disease typically do not survive past their teens.

Disease Ontology : 12 A neuronal ceroid lipofuscinosis that is characterized by late-infantile onset of symptoms (seizures or motor impairment followed by mental regression, myoclonus, speech impairment, loss of vision, and personality disorders) and has material basis in homozygous or compound heterozygous mutation in the MFSD8 gene on chromosome 4q28.
