    It is suggested that the majority of symptoms found in 7q trisomic patients are not specific, are little characteristic and are unable to evoke this specific chromosomal defect. Therefore, the possibility of recognizing patients, with duplications of 7q, on clinical grounds alone, is rather unrealistic.
