Function
DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Common component of RNA polymerases I and III which synthesize ribosomal RNA precursor pre-rRNA and short non-coding RNAs including 5S rRNA, snRNAs, tRNAs and miRNAs, respectively. {ECO:0000250|UniProtKB:P28000, ECO:0000269|PubMed:20413673, ECO:0000269|PubMed:35637192}.

HI Evidence:
  • PUBMED: 21131976
    Dauwerse et al. (2011) describe 17 mutations in POLR1D detected in 20 unrelated individuals with clinical diagnoses of Treacher-Collins syndrome and no mutations in TCOF1, including 10 different nonsense variants. This group also describes a 156 kb de novo deletion encompassing all of POLR1D and the first exon of LNX2. The variants segregated with disease in familial cases. Two families demonstrated reduced penetrance.
  • PUBMED: 25790162
    Vincent et al. (2016) evaluated 146 patients with Treacher-Collins syndrome. They reported nine variants in POLR1D, including 7 molecular variants and 2 intragenic deletions. Variants were inherited from an asymptomatic parent in 4/9 cases. All mutations were heterozygous except one missense variant that was homozygous and inherited in a recessive manner. Based on the 19 clinical features compared, POLR1D may account for somewhat more mild phenotype but additional studies are needed.
