What is the official name of the POLR1D gene?The official name of this gene is “polymerase (RNA) I polypeptide D, 16kDa.” POLR1D is the gene's official symbol. The POLR1D gene is also known by other names, listed below. Read more about gene names and symbols on the About page. What is the normal function of the POLR1D gene?The POLR1D gene provides instructions for making one part (subunit) of two related enzymes called RNA polymerase I and RNA polymerase III. These enzymes are involved in the production (synthesis) of ribonucleic acid (RNA), a chemical cousin of DNA. Both enzymes help synthesize a form of RNA known as ribosomal RNA (rRNA). RNA polymerase III also plays a role in the synthesis of several other forms of RNA, including transfer RNA (tRNA). Ribosomal RNA and transfer RNA assemble protein building blocks (amino acids) into functioning proteins, which is essential for the normal functioning and survival of cells. Based on its involvement in Treacher Collins syndrome (described below), the POLR1D gene appears to play a critical role in the early development of structures that become bones and other tissues of the face. How are changes in the POLR1D gene related to health conditions?
Where is the POLR1D gene located?Cytogenetic Location: 13q12.2 Molecular Location on chromosome 13: base pairs 28,194,879 to 28,241,558 The POLR1D gene is located on the long (q) arm of chromosome 13 at position 12.2. More precisely, the POLR1D gene is located from base pair 28,194,879 to base pair 28,241,558 on chromosome 13. See How do geneticists indicate the location of a gene? in the Handbook.
