ABSTRACT
Haploinsufficiency of FOXP1 gene is responsible for a neurodevelopmental disorder presenting with intellectual disability (ID), autism spectrum disorder (ASD), hypotonia, mild dysmorphic features, and multiple congenital anomalies. Joint contractures are not listed as a major feature of FOXP1-related disorder. We report five unrelated individuals, each harboring likely gene disruptive de novo FOXP1 variants or whole gene microdeletion, who showed multiple joint contractures affecting at least two proximal and/or distal joints. Consistent with the phenotype of FOXP1-related disorder, all five patients showed developmental delay with moderate-to-severe speech delay, ID, ASD, and facial dysmorphic features. FOXP1 is implicated in neuronal differentiation and in organizing motor axon projections, thus providing a potential developmental basis for the joint contractures. The combination of joint contractures and neurodevelopmental disorders supports the clinical suspicion of FOXP1-related phenotype.
