    ### Instruction:
    What are the genetic changes related to Nicolaides-Baraitser syndrome ?
    ### Response:
    Nicolaides-Baraitser syndrome is caused by mutations in the SMARCA2 gene. This gene provides instructions for making one piece (subunit) of a group of similar protein complexes known as SWI/SNF complexes. These complexes regulate gene activity (expression) by a process known as chromatin remodeling.
