Outline of the thesis
The autosomal dominant myopathy facioscapulohumeral muscular dystrophy (FSHD) is the third most common inherited neuromuscular disorder and is characterized by progressive muscle weakness and atrophy, initially involving muscles in the face, upper arm and shoulder girdle. FSHD is caused by contractions of the D4Z4 repeat on chromosome 4q35. An almost identical D4Z4 repeat is present on chromosome 10q26 but contractions of this repeat have never been associated with FSHD. Because transcriptional activity from D4Z4 has never been demonstrated, other disease models have been proposed in which the D4Z4 contraction causes inappropriate transcription of cisand/or transgenes.
