Recessive Mutations in POLR3B, Encoding the Second

Nov 11, 2011Mutations in POLR3A encoding the largest subunit of RNA polymerase III (Pol III) were found to be responsible for the majority of cases presenting with three clinically overlapping hypomyelinating leukodystrophy phenotypes. We uncovered in three cases without POLR3A mutation recessive mutations in POLR3B, which codes for the second largest subunit of Pol III.Recessive Mutations in POLR3B, Encoding the Second Mutations in POLR3A encoding the largest subunit of RNA polymerase III (Pol III) were found to be responsible for the majority of cases presenting with three clinically overlapping hypomyelinating leukodystrophy phenotypes.

Recessive Mutations in POLR3B Encoding RNA Polymerase

Oct 19, 2015The diagnosis of 4H leukodystrophy (hypomyelination, hypogonadotropic hypogonadism, and hypodontia) is based on clinical findings and magnetic reance imaging (MRI). Recently, mutations of the genes encoding Pol III (RNA polymerase III) subunit A (POLR3A) and subunit B (POL3B) have been identified as the genetic causes of hypomyelination.

Pol III-related leukodystrophy MedlinePlus Genetics

Pol III-related leukodystrophy is caused by mutations in the POLR3A or POLR3B gene. These genes provide instructions for making the two largest parts (subunits) of an enzyme called RNA polymerase III. This enzyme is involved in the production (synthesis) of ribonucleic acid (RNAPol III-related leukodystrophy MedlinePlus GeneticsPol III-related leukodystrophy is caused by mutations in the POLR3A or POLR3B gene.

POLR3A gene MedlinePlus Genetics

The POLR3A gene provides instructions for making the largest piece (subunit) of an enzyme called RNA polymerase III. This enzyme is involved in the production (synthesis) of ribonucleic acid (RNA), a chemical cousin of DNA. The RNA polymerase III enzyme attaches (binds) to DNA and synthesizes RNA molecules in accordance with the instructions carried by the DNA, a process called transcription.OMIM Entry - * 614258 - POLYMERASE III, RNA, SUBUNIT A; POLR3APOLR3A is the largest subunit of RNA polymerase III. RNA polymerase III is a DNA-directed RNA polymerase that transcribes genes encoding ribosomal 5S RNA (), tRNAs, U6 small nuclear RNA (see 180692), mitochondrial RNA-processing RNA (RMRP; 157660), H1 RNA (RPPH1; 608513), Y RNAs (see 601821), and 7SK RNA (RN7SK; 606515) (summary by Sepehri and Hernandez, 1997).

This system comprises several interrelated signal transduction pathways, one of which implicates the viral DNA sensor RNA polymerase (Pol) III. However, the link of this polymerase to innate immunity in humans remains largely unknown. Here, we describe a homozygous mutation (D40H) in the POLR3E gene,
