    35 SMCs derived from all the human chromosomes, except 6, were studied.
    In nine cases without an aberrant phenotype, neither partial proximal trisomies nor UPD could be detected. Small proximal trisomies of 1p, 1q, 2p, 6p, 6q, 7q, 9p, and 12q seem to lead to clinical manifestations, whereas partial proximal trisomies of 2q, 3p, 3q, 5q, 7p, 8p, 17p, and 18p may not be associated with significant clinical symptoms.
