Este hallazgo puede permitir aislar el gen que predispone a este tipo de migraña. Los autores analizaron marcadores genéticos en muestras de sangre de 50 familias finlandesas con tres o más miembros de distintas generaciones afectados por este tipo de cefalea. En el 30% de los 430 individuos estudiados descubrieron tres marcadores frecuentes relacionados con la región 4q24 del cromosoma 4.
Una vez localizada la región cromosómica será más sencillo identificar el posible gen o genes que predisponen a la migraña con aura, lo cual también sentará las basas para el desarrollo de fármacos más efectivos.
