| Abstract: | We have analyzed the segregation of five loci in the region Xq27/28 in a large family affected by the fragile X syndrome. The marker DXS115 (767) is shown to be polymorphic with the enzyme PstI, as well as with BstXI. This marker will be useful in the analysis of both fragile X and haemophilia A families. The data presented here are consistent with the following order of loci: Xcen-F9-DXS105(cX55.7,55E)-DXS98(4D-8)- FRAXA-DXS52(St14)-DXS115(767)-qter. |
