Relevance to Autism
Association has been found between the ASTN2 gene and autism. Glessner et al. (2009) identified a rare ASTN2 deletion in an autism case. Another study found a link between rare ASTN2 CNVs and schizophrenia.
Molecular Function
This gene encodes a protein that is expressed in the brain and may function in neuronal migration, based on functional studies of the related astrotactin 1 gene in human and mouse. A deletion at this locus has been associated with schizophrenia.
