FMR3 is a novel gene associated with FRAXE CpG island and transcriptionally silent in FRAXE full mutations.

Abstract excerpt

We have identified a novel gene, FMR3, originating from the FRAXE CpG island. The FMR3 gene is transcribed from the opposite strand to the FMR2 gene. Analogous to the silencing of the FMR1 and FMR2 genes, FMR3 transcription is extinguished by FRAXE full mutation. Although the role of FMR3 in FRAXE associated mild to borderline mental retardation is not yet clear, lack of expression of FMR3 in FRAXE full mutation...
