    What are the genetic changes related to Beckwith-Wiedemann syndrome ?
    ### Response:
    The genetic causes of Beckwith-Wiedemann syndrome are complex. The condition usually results from the abnormal regulation of genes in a particular region of chromosome 11. People normally inherit one copy of this chromosome from each parent. For most genes on chromosome 11, both copies of the gene are expressed, or "turned on," in cells.
