An allele-aware approach identifies altered nuclear associations of the contracted D4Z4 array at the FSHD locus

ABSTRACT: Facioscapulohumeral dystrophy (FSHD) is caused by a deletion in a D4Z4 macrosatellite repeat array in the 4q subtelomere that leads to somatic de-repression of the transcription factor DUX4. It is not fully understood how array contractions cause de-repression, but they alter the local chromatin structure of D4Z4, resulting in loss of heterochromatic markers. In order to determine whether pathogenic contractions also alter the nuclear organization of the FSHD locus, we designed an allele-aware, high-throughput circular chromosome conformation capture assay (4C-seq) that distinguishes the two 4q copies of the locus from each other and from a paralogous locus in the 10q subtelomere. Using a short sequence length polymorphism (SSLP) four kilobasepairs from the array as âharacterized the genom
