Trait

Visually-induced seizure

Seizures evoked by visual stimuli. This includes clinical seizures induced by strobe lighting, television and other screens, flickering environmental lighting and self-induction by causing a strobe effect.

3 genes linked to Visually-induced seizure

Changes in these genes cause rare conditions in which Visually-induced seizure is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.

Gene	How often it is seen	Conditions
CHD2chromodomain helicase DNA binding protein 2	Often (30–79%)	In 1 condition
CPA6carboxypeptidase A6	Sometimes (5–29%)	In 1 condition
SCN1Asodium voltage-gated channel alpha subunit 1	Not recorded	In 1 condition

How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
