Genes affected
POLR2I (HGNC:9196): (RNA polymerase II subunit I) This gene encodes a subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. This subunit, in combination with two other polymerase subunits, forms the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA. The product of this gene has two zinc finger motifs with conserved cysteines and the subunit does possess zinc binding activity. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2023The c.256T>C (p.C86R) alteration is located in exon 4 (coding exon 4) of the POLR2I gene. This alteration results from a T to C substitution at nucleotide position 256, causing the cysteine (C) at amino acid position 86 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
