The results of the present study strongly suggest that most mitotic D4Z4 rearrangements occur via an interchromatid gene conversion mechanism without crossover in which the donor

In conclusion, we have shown (1) that the D4Z4 repeat reduction associated with FSHD arises in ~40% of the de novo cases, mitotically, in either parent or patient; (2) that the

We examined two CpG methylation-sensitive restriction sites (BsaAI and FseI) in the first (proximal) unit of the D4Z4 repeat array on chromosome 4q35 (see Supplementary subjec ts

When these two groups were analysed separately, the relationship was abolished (FSHD patients: BsaAI P = 0.24 and FseI P = 0.45; control individuals: BsaAI P = 0.54 and FseI P =

Because DNA from monosomic individuals provides a unique opportunity to examine DNA methylation of a single healthy or disease chromosome 4 repeat array, we took advantage of
