MTNR1A and facioscapulohumeral muscular dystrophy: Other 4q35.2 genes represented on the microarray were FAT1 (the only 4q35.2 gene with muscle-lineage specific DNaseI hypersensitivity sites [24]), F11, CYP4V2, MTNR1A, ZFP42, TRIML1, and TRIML2. They showed no differences in RNA signal between FSHD and control myogenic cells.
