Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SCN1A gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. Plays a key role in brain, probably by regulating the moment when neurotransmitters are released in neurons. Involved in sensory perception of mechanical pain: activation in somatosensory neurons induces pain without neurogenic inflammation and produces hypersensitivity to mechanical, but not thermal stimuli. {ECO:0000250|UniProtKB:A2APX8}.;
Disease
DISEASE: Generalized epilepsy with febrile seizures plus 2 (GEFS+2) [MIM:604403]: A rare autosomal dominant, familial condition with incomplete penetrance and large intrafamilial variability. Patients display febrile seizures persisting sometimes beyond the age of 6 years and/or a variety of afebrile seizure types. This disease combines febrile seizures, generalized seizures often precipitated by fever at age 6 years or more, and partial seizures, with a variable degree of severity. {ECO:0000269|PubMed:10742094, ECO:0000269|PubMed:11254444, ECO:0000269|PubMed:11254445, ECO:0000269|PubMed:11524484, ECO:0000269|PubMed:11756608, ECO:0000269|PubMed:12535936, ECO:0000269|PubMed:12576172, ECO:0000269|PubMed:12919402, ECO:0000269|PubMed:14672992, ECO:0000269|PubMed:15525788, ECO:0000269|PubMed:15694566, ECO:0000269|PubMed:15715999, ECO:0000269|PubMed:16525050, ECO:0000269|PubMed:17347258, ECO:0000269|PubMed:17507202, ECO:0000269|PubMed:17561957, ECO:0000269|PubMed:17927801, ECO:0000269|PubMed:17928445, ECO:0000269|PubMed:18251839, ECO:0000269|PubMed:18413471, ECO:0000269|PubMed:18566737, ECO:0000269|PubMed:19339291, ECO:0000269|PubMed:19464195, ECO:0000269|PubMed:19522081, ECO:0000269|PubMed:20117752, ECO:0000269|PubMed:20550552, ECO:0000269|PubMed:20600615, ECO:0000269|PubMed:20729507, ECO:0000269|PubMed:21248271, ECO:0000269|PubMed:21864321}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Epileptic encephalopathy, early infantile, 6 (EIEE6) [MIM:607208]: A severe form of epileptic encephalopathy characterized by generalized tonic, clonic, and tonic-clonic seizures that are initially induced by fever and begin during the first year of life. Later, patients also manifest other seizure types, including absence, myoclonic, and simple and complex partial seizures. Psychomotor development delay is observed around the second year of life. Some patients manifest a borderline disease phenotype and do not necessarily fulfill all diagnostic criteria for core EIEE6. EIEE6 is considered to be the most severe phenotype within the spectrum of generalized epilepsies with febrile seizures-plus. {ECO:0000269|PubMed:11359211, ECO:0000269|PubMed:12083760, ECO:0000269|PubMed:12566275, ECO:0000269|PubMed:12754708, ECO:0000269|PubMed:12821740, ECO:0000269|PubMed:14504318, ECO:0000269|PubMed:14672992, ECO:0000269|PubMed:14738421, ECO:0000269|PubMed:15087100, ECO:0000269|PubMed:15944908, ECO:0000269|PubMed:16122630, ECO:0000269|PubMed:16458823, ECO:0000269|PubMed:16713920, ECO:0000269|PubMed:17054684, ECO:0000269|PubMed:17054685, ECO:0000269|PubMed:17129991, ECO:0000269|PubMed:17347258, ECO:0000269|PubMed:17561957, ECO:0000269|PubMed:18413471, ECO:0000269|PubMed:18639757, ECO:0000269|PubMed:18930999, ECO:0000269|PubMed:19522081, ECO:0000269|PubMed:19563458, ECO:0000269|PubMed:19589774, ECO:0000269|PubMed:19783390, ECO:0000269|PubMed:20110217, ECO:0000269|PubMed:20431604, ECO:0000269|PubMed:20452746, ECO:0000269|PubMed:20522430, ECO:0000269|PubMed:20729507, ECO:0000269|PubMed:21248271, ECO:0000269|PubMed:21864321, ECO:0000269|PubMed:22092154, ECO:0000269|PubMed:22612257, ECO:0000269|PubMed:23195492, ECO:0000269|PubMed:23662938, ECO:0000269|PubMed:23708187, ECO:0000269|PubMed:25818041, ECO:0000269|PubMed:26993267, ECO:0000269|PubMed:27864847, ECO:0000269|PubMed:28544625}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Intractable childhood epilepsy with generalized tonic- clonic seizures (ICEGTC) [MIM:607208]: A disorder characterized by generalized tonic-clonic seizures beginning usually in infancy and induced by fever. Seizures are associated with subsequent mental decline, as well as ataxia or hypotonia. ICEGTC is similar to SMEI, except for the absence of myoclonic seizures. {ECO:0000269|PubMed:12566275, ECO:0000269|PubMed:16210358, ECO:0000269|PubMed:17507202, ECO:0000269|PubMed:23195492, ECO:0000269|PubMed:23708187}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Migraine, familial hemiplegic, 3 (FHM3) [MIM:609634]: A subtype of migraine associated with transient blindness in some families. Migraine is a disabling symptom complex of periodic headaches, usually temporal and unilateral. Headaches are often accompanied by irritability, nausea, vomiting and photophobia, preceded by constriction of the cranial arteries. The two major subtypes are common migraine (migraine without aura) and classic migraine (migraine with aura). Classic migraine is characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred vision, hallucinations, vertigo, numbness and difficulty in concentrating and speaking. {ECO:0000269|PubMed:16054936, ECO:0000269|PubMed:17397047, ECO:0000269|PubMed:18021921, ECO:0000269|PubMed:19332696}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Febrile seizures, familial, 3A (FEB3A) [MIM:604403]: Seizures associated with febrile episodes in childhood without any evidence of intracranial infection or defined pathologic or traumatic cause. It is a common condition, affecting 2-5% of children aged 3 months to 5 years. The majority are simple febrile seizures (generally defined as generalized onset, single seizures with a duration of less than 30 minutes). Complex febrile seizures are characterized by focal onset, duration greater than 30 minutes, and/or more than one seizure in a 24 hour period. The likelihood of developing epilepsy following simple febrile seizures is low. Complex febrile seizures are associated with a moderately increased incidence of epilepsy. {ECO:0000269|PubMed:16326807, ECO:0000269|PubMed:19522081}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Note=SCN1A mutations may be involved in Panayiotopoulos syndrome, a benign age-related focal seizure disorder occurring in early and mid-childhood. It is characterized by seizures, often prolonged, with predominantly autonomic symptoms, and by an electroencephalogram that shows shifting and/or multiple foci, often with occipital predominance. Autonomic seizures in Panayiotopoulos syndrome consist of episodes of disturbed autonomic function with emesis as the predominant symptom. Cardiorespiratory arrest is exceptional. {ECO:0000269|PubMed:17679682, ECO:0000269|PubMed:19339291, ECO:0000269|PubMed:19522081}.;
