Six cases of trisomy 4p and three of trisomy 9p are reported. Growth retardation is an aspecific clinical sign, present in both of these “new autosomal” syndromes. Growth hormone determinations fit in the normal range. The attempts to subclassify these disorders correlating the severity of clinical manifestations and the size of the imbalanced chromosome segment, are considered unrealistic approaches.
