Genes affected

LOC124903407 (HGNC:):

MIR379 (HGNC:31872): (microRNA 379) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]

MEG8 (HGNC:14574): (maternally expressed 8, small nucleolar RNA host gene) This gene is located in a cluster of imprinted genes on chromosome 14q32.3. It encodes a a non-protein coding transcript that is preferentially expressed from the maternal allele in skeletal muscle, and appears to be coordinately regulated with other imprinted genes in this region.
