15q.13.3 microdeletion has been described in a variety of neurodevelopmental disorders. Epilepsy appears to be a common feature and, specifically, the 15q13.3 microdeletion is found in about 1% of patients with idiopathic generalized epilepsy. Recently, absence seizures with intellectual disability (ID) have been reported in patients carrying this mutation. We describe two families in which several affected members carry a 15q13.3 microdeletion in a pattern suggestive of autosomal dominant inheritance. Their phenotype includes mainly absence epilepsy and mild ID, suggesting only similarities with genetic/idiopathic generalized epilepsies but not typical features. The importance of studying such families is crucial to broaden the phenotype and understand the long-term outcome of patients with this condition.
