Relevance to Autism
A de novo nonsense variant in the CUX2 gene was identified in an ASD proband from the Autism Sequencing Consortium in De Rubeis et al., 2014. Chatron et al., 2018 identified nine patients with a recurrent de novo missense variant in the CUX2 gene (p.Glu590Lys) that presented with developmental and epileptic encephalopathy; in addition to recurrent phenotypes including epilepsy and intellectual disability, several individuals with this variant also presented with autistic features and/or motor stereotypies.
Molecular Function
This gene encodes a protein which contains three CUT domains and a homeodomain; both domains are DNA-binding motifs. The encoded protein may be a transcription factor involved in neural specification.
