FSHD4ICFICF1M.HsaIIIB
Chromosome 20
Chromosome location 20q11.21
Summary CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA met
