    30 autistic children and 30 controls were examined.
    The cFS found were at 1p21, 1p36, 1q44, 2p16, 2q37, 3p24, 4q27, 6p22, 6p25, 7q31, 7q32, 10q25, 11p13, 13q21, 14q23, 15q22 and 16q22. The rFS found were at 2q13, 6p23, 10q23, 12q13 and 20p11.

    Parental karyotypes were normal. No evidence of translocation of the missing material was detected. The causal relationship of the abnormalities in the proposita to the deleted chromosome 20 is uncertain. The 11-month-old patient had a dysmorphic syndrome, multiple congenital anomalies, psychomotor and growth retardation.
