Added comment: Expansion of a polymorphic CGG-repeat located at the 5' end of the C11orf80 gene causes expression of the folate-sensitive fragile site FRA11A. The CGG-repeat elongation coincides with hypermethylation of the adjacent CpG island and subsequent transcriptional silencing of the C11orf80 gene. The expansion was identified in the 15-year-old proband with intellectual disability as well as in phenotypically normal members of the family.
