Markers in and around the dystrophin gene

(last modified January 6, 2006)


This page gives an overview of the markers that have been described in and directly flanking the DMD gene, including RFLP (Restriction Fragment Length Polymorphism) and VNTR (Variable Number of Tandem Repeats, CA-repeats); for details regarding their localization, see "Sequences / markers in and around the dystrophin gene" . These markers can be used for mapping studies (linkage, association) in relation to DMD/BMD and the DMD-gene. Rarely, these markers are used these to screen carriers for deletions.
