Gene Expression and Pathophysiology Comments
Small rare recurrent deletion of chromosome 2q21.1, in which GPR148 might be the possible candidate gene, is pathogenic for developmental delay (DD)/intellectual disability (ID), attention-deficit hyperactivity disorder (ADHD), epilepsy and other neurobehavioral abnormalities [1].
