A newly described partial trisomy of the short arm of chromosome number 7 is reported in a familial translocation between 7 and 22. The unbalanced translocation was found in one family member, the propositus, and the balanced form in 5 other members. The possibility of this translocation being a rare telomeric attachment previously undescribed in humans is discussed. Prominent clinical features...

Two mentally and physically retarded girls, one with an interstitial deletion 7 (pter leads to q21::q32 leads to qter), and the other with an interstitial deletion 7 (pter leads to q11::q22 leads to qter), are described. Their clinical features are compared with those of 11 earlier reported cases with a deletion 7q. The Hageman factor, the locus of which is assigned to the distal part of 7q, wa...

Wide-spread provision of broadband multimedia services requires a powerful signaling system, which does not exist yet. Future signaling will have to support calls with several participants, several connections and heterogeneous terminals. This paper introduces a new framework for an overall signaling system designed to meet the requirements of multimedia services. An object-oriented call model ...
