The localization of the gene for the majority of cases of facioscapulohumeral muscular dystrophy is established as 4q35-qter (FSHD1A), although locus heterogeneity has been demonstrated with a minority of families unlinked to 4q. In FSHD1A, the disease is associated with a deletion of 3.3 kb repeats from a tandem repeat located near the as-yet-unidentified gene. This repeat cross-hybridizes with a telomeric region on 10q, making this cross-hybridizing region a feasible candidate gene for FSHD1B. We have tested the most telomeric marker on 10q (sAVA4) and excluded ∼17 cM on either side of this marker as harboring the FSHD1B gene.
