POLR1D, Official Symbol POLR1Dprovided by HGNC Official Full Name RNA polymerase I and III subunit Dprovided by HGNC Primary source HGNC:HGNC:20422 See related Ensembl:ENSG00000186184 MIM:613715; AllianceGenome:HGNC:20422 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as AC19; RPA9; TCS2; RPA16; RPAC2; RPC16; POLR1C; RPO1-3 Summary The protein encoded by this gene is a component of the RNA polymerase I and RNA polymerase III complexes, which function in the synthesis of ribosomal RNA precursors and small RNAs, respectively. Mutations in this gene are a cause of Treacher Collins syndrome (TCS), a craniofacial development disorder. Alternative splicing results in multiple transcript variants.
