Witryna25 sty 2024 · SNHG14 transcripts originate from the PWS/AS locus and are paternally expressed. The SNHG14 transcriptional unit is subject to alternative splicing and produces a long primary noncoding transcript that initiates from the U exons upstream of the PWS imprinting control (IC) region. This transcript includes PWS-IC, SNURF … WitrynaMost genes are expressed from both parental chromosomes; however, a small number of genes in mammals are imprinted and expressed in a parent-of-origin specific …
