Genes affected
POLR2M (HGNC:14862): (RNA polymerase II subunit M) This gene encodes a subunit of a specific form of RNA polymerase II termed Pol II(G). The encoded protein may act as a negative regulator of transcriptional activation by the Mediator complex. Alternative splicing results in multiple transcript variants. There is a pseudogene for this gene on chromosome 4. Readthrough transcription between this gene and the neighboring upstream gene MYZAP (myocardial zonula adherens protein) is represented with GeneID 145781. [provided by RefSeq, Oct 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 24, 2023The c.691T>C (p.Y231H) alteration is located in exon 2 (coding exon 2) of the POLR2M gene. This alteration results from a T to C substitution at nucleotide position 691, causing the tyrosine (Y) at amino acid position 231 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
