An autosomal dominant form of syndromic intellectual disability caused by mutation in the FOXP1 gene. It is characterized by global developmental delay with moderate to severe speech delay that affects expressive speech. Most patients have difficulty articulating words.

Some patients have autistic features and/or behavioral problems. Congenital malformations may be associated. All reported cases have occurred de novo (without any cases in the family).
