Linkage analysis was performed in 19 families segregating for the Wiskott-Aldrich syndrome (WAS) and in 1 family with X-linked thrombocytopenia using nine polymorphic DNA markers spanning the interval DXS7-DXS14. The results confirm close linkage of WAS to the DXS7, TIMP, OATL1, DXS255, DXS146, and

โฆ Synopsis
To provide a more precise genetic map of the p22.3-p21.2 region on the short arm of the human X chromosome, we performed multilocus linkage studies in an expanded database including 31 retinoschisis families and 40 normal families. Twelve loci from this region were examined. Although significant lod scores were observed between various pairs of markers by two-point linkage analysis, the confidence limits were found to be broad. The most likely gene order on the basis of multilocus analysis was Xpter-DXS89-DXS85-DXS16-(DXS207,DXS43++ +)-DXS274-(DXS41, DXS92)-ZFX-DXS164-Xcen. All other alternative orders were excluded by odds of at least 40:1.
