Abstract
A new locus for restless legs syndrome (RLS3) was identified on chromosome 9p24-22. The authors analyzed transmission disequilibrium tests (TDTs) and affecteds-only linkage analysis in one large family of Bavarian origin, taking into account age at onset. P values were 0.0054 for marker D9S1810 for TDT and 0.0009 for the affecteds-only linkage analysis, providing a confirmation of RLS3. This study narrows the region containing the autosomal dominant RLS3 locus to 11.1 cM (16.6 Mbp).
