 The final known associated gene is EFHC1.Myoclonin1/EFHC1 encodes for a protein that has been known to play a wide range of roles from cell division, neuroblast migration and synapse/dendrite formation.EFHC1 is expressed in many tissues, including the brain, where it is localized to the soma and dendrites of neurons, particularly the hippocampal CA1 region, pyramidal neurons in the cerebral cortex, and Purkinje cells in the cerebellum.
