    What are the genetic changes related to Russell-Silver syndrome ?
    ### Response:
    The genetic causes of Russell-Silver syndrome are complex. The disorder often results from the abnormal regulation of certain genes that control growth. Research has focused on genes located in particular regions of chromosome 7 and chromosome 11.  People normally inherit one copy of each chromosome from their mother and one copy from their father.
