1,333 Possible Causes for Mutation in the SCN1A Gene, Small Hippocampi, Visual Hallucination

  • Temporal Lobe Epilepsy

    For example, most infants with Dravet syndrome, a type of epilepsy associated with seizures that begin before the age of one year, carry a mutation in the SCN1A gene that[] The control of water movement is achieved through a family of small integral membrane channel proteins called aquaporins (AQPs).[] In a study published this week in Medical Humanities, the authors feel that temporal lobe epilepsy is a more likely explanation as it can produce complex visual hallucinations[]

  • Early Infantile Epileptic Encephalopathy Type 6

    Abstract BACKGROUND: Mutations in the gene encoding the alpha subunit of the voltage-gated sodium channel SCN1A are associated with several epilepsy syndromes.[] (E) Coronal views of the hippocampi at 2 months show bilateral small hippocampi with left hippocampal malrotation.[] In Idiopathic Childhood Epilepsy of Gastaut seizures are brief, diurnal and frequent, consisting generally of elementary visual hallucinations and/or ictal blindness.[]

  • Panayiotopoulos Syndrome

    Mutations in the SCN1A gene have been associated with the development of this syndrome.[] Complex visual hallucinations, visual illusions and other symptoms resulting from more anterior ictal spreading rarely occur from the start.[] .  May experience febrile myoclonus  Associated with mutations of the SCN1A sodium channel gene. 17.  Previously called early-benign childhood seizures with occipital spikes[]

  • Epilepsy

    De novo mutations in the sodium-channel gene SCN1A cause severe myoclonic epilepsy of infancy.[] , such as blindness, visual hallucinations, illusions, and distorted scenery like macropsia, where everything surrounding you seems larger than normal.[] The cortex is the outer layer of the brain, and seizure symptoms can vary from unusual sensations to visual hallucinations, emotional changes, or convulsions.[]

  • Epileptic Aura

    Interestingly, mutations in all three FHM genes [CACNA1A (FHM1), ATP1A2 (FHM2) and SCN1A (FHM3)] can also cause epileptic seizures.[] The elementary visual hallucinations detailed cannot be anything else but visual seizures.[] Case 1, a 14-year-old boy with weekly episodes of visual hallucinations beginning at age 8, first complained of concentric spherical rings of red and yellow moving from left[]

  • Basilar Migraine

    Mutations in three genes have been described in FHM patients: CACNA1A (FHM1), ATP1A2 (FHM2) and SCN1A (FHM3).[] Symptoms may include scintillating scotomata, formed stereotyped visual hallucinations in a single visual field or bilaterally, micropsia, and tunnel vision. [80] Other auras[] […] castles (teichopsia), wavy images or hallucinations.[]

  • Generalized Epilepsy with Febrile Seizures Plus

    Here, we provide the first report of clinical presentation and mutational analysis of SCN1A gene in 36 Malaysian GEFS patients.[] The syndrome is usually associated with visual hallucinations.[] It was associated with mutations in the neuronal voltage-gated sodium channel subunit gene (SCN1A, SCN2A, SCN1B) and ligand-gated gamma aminobutyric acid receptors genes ([]
