It will be important to determine the expression of moesin protein and the MSNP1AS noncoding RNA in neurons derived from patients with the ASD-associated rs4307059 allele, as well as from patients with Cri-du-chat syndrome with deletion of chromosome 5p14.1, as these experiments may provide further evidence of a contribution of MSNP1AS to altered brain development. Here, MSN is linked to Cri-du-chat syndrome.
