Abstract: A method for controlling communication in a Mobile Integrated Voice and Dat (IVD) system, the system having a plurality of Cell  Stations  (CS's)  interconnected through communication networks including a LAN, A PBX telephone network and Personal Stations (PS's). A first CS registers the LAN identifier of a first PS in accordance with the first PS that exists within its own radio cell, and assigns a PBX telephone number to the first PS. Subsequently, a calling information which includes a LAN identifier for the second PS and the PBX telephone number assigned to the first PS is broadcast via a LAN. Thereafter, the second CS which registers the LAN identifier of the second PS receives the calling information via a LAN and transfers the information of the second mobile station via radio link.  The second PS then dials the PBX telephone number included in the calling information. Thus, the link between the first PS and the second PS is connected when the first PS receives the calling.

Abstract: Familial dysautonomia (FD), the Riley-Day syndrome, is an autosomal recessive disorder characterized by developmental loss of neurons from the sensory and autonomic nervous system. It is limited to the Ashkenazi Jewish population, where the carrier frequency is 1 in 30. We have mapped the FD gene to the chromosome region 9q31-q33 by linkage with ten DNA markers in twenty-six families. The maximum lod score of 21.1 with no recombinants was achieved with D9S58. This marker also showed strong linkage disequilibrium with FD, with one allele present on 73 % of all affected chromosomes compared, to 5.4 % of control chromosomes (X2 = 3142, 15 d.f. p < 0.0001). The other nine markers, distributed within 23 cM proximal or distal to D9S58, also yielded significant linkage to FD. D9S53 and D9S105 represent the closest flanking markers for the disease gene. This localization will permit prenatal diagnosis of FD in affected families.
