DXS539, a polymorphic DNA marker proximal of the fragile-X gene

Hum Genet. 1993 Mar;91(1):80-2. doi: 10.1007/BF00230229.

Abstract

We report a new polymorphic DNA marker (pJH89, DXS539) proximal to the fragile-X site. The pJH89 probe identifies a TaqI and a NcoI restriction fragment length polymorphism (combined heterozygosity of 42%) and is linked to the fragile-X locus with a maximal LOD score of 12 at 4 cM. Multipoint linkage analysis and physical mapping studies indicate that the pJH89 probe is located within in the interval defined by the markers DXS369 and DXS548.
