title: Assignment of the X-linked torsion dystonia gene to Xq21 by linkage analysis.
abstract: We performed linkage analysis of X-linked torsion dystonia (XLTD) in 7 Filipino families, studying DNA from a total of 36 family members (9 obligate carrier females, and 18 affected and 9 unaffected males). Application of 21 informative X chromosomal DNA sequences allowed assignment of the XLTD locus to the proximal long arm of the X chromosome (Xq21). A maximum LOD score of 3.06 at [symbol: see text] = 0.0 was obtained with DXYS2, previously assigned to Xq21.3.
