A new microduplication syndrome encompassing the region of the Miller-Dieker (17p13 deletion) syndrome.

abstract：:BACKGROUND Mutations in SCN1A can cause genetic epilepsy with febrile seizures plus (GEFS+, inherited missense mutations) or Dravet syndrome (DS, de novo mutations of all types). Although the mutational spectra are distinct, these disorders share major features and 10% of DS patients have an inherited SCN1A mutation. ...
