β¦ Synopsis
A highly informative microsatellite marker, DXS426, which maps proximal to DXS7 in the interval Xp11.4-Xp11.23, has been used to refine further the localisation of the gene for Norrie disease (NDP). The results from a multiply informative crossover localize the NDP gene proximal to DXS7. In conjunction with information from 2 NDP patients who have a deletion for DXS7 but not for DSX426, our data indicate that the NDP gene lies between DXS7 and DXS426 on proximal Xp.

A disease gene introduced into a rapidly growing population by a single individual remains in strong linkage disequilibrium with the surrounding molecular markers. Mapping strategies taking advantage of this phenomenon allow increased mapping resolution as compared to pedigree analysis. Demographic
