Genes affected

POLR2E (HGNC:9192): (RNA polymerase II, I and III subunit E) This gene encodes the fifth largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. This subunit is shared by the other two DNA-directed RNA polymerases and is present in two-fold molar excess over the other polymerase subunits. An interaction between this subunit and a hepatitis virus transactivating protein has been demonstrated, suggesting that interaction between transcriptional activators and the polymerase can occur through this subunit. A pseudogene is located on chromosome 11. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]

The c.8A>C (p.D3A) alteration is located in exon 1 (coding exon 1) of the POLR2E gene. This alteration results from a A to C substitution at nucleotide position 8, causing the aspartic acid (D) at amino acid position 3 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
