Genes affected
POLR2C (HGNC:9189): (RNA polymerase II subunit C) This gene encodes the third largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. The product of this gene contains a cysteine rich region and exists as a heterodimer with another polymerase subunit, POLR2J. These two subunits form a core subassembly unit of the polymerase. A pseudogene has been identified on chromosome 21. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2024The c.28C>T (p.R10W) alteration is located in exon 1 (coding exon 1) of the POLR2C gene. This alteration results from a C to T substitution at nucleotide position 28, causing the arginine (R) at amino acid position 10 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
