Genes affected

RPAP2 (HGNC:25791): (RNA polymerase II associated protein 2) Enables RNA polymerase II CTD heptapeptide repeat phosphatase activity. Involved in dephosphorylation of RNA polymerase II C-terminal domain and snRNA transcription. Located in cytosol and nucleolus. Part of RNA polymerase II, holoenzyme. [provided by Alliance of Genome Resources, Apr 2022]

RPAP2 links:

GLMN (HGNC:14373): (glomulin, FKBP associated protein) This gene encodes a phosphorylated protein that is a member of a Skp1-Cullin-F-box-like complex. The protein is essential for normal development of the vasculature and mutations in this gene have been associated with glomuvenous malformations, also called glomangiomas. Multiple splice variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2016]
