Genes affected

LEO1 (HGNC:30401): (LEO1 homolog, Paf1/RNA polymerase II complex component) LEO1, parafibromin (CDC73; MIM 607393), CTR9 (MIM 609366), and PAF1 (MIM 610506) form the PAF protein complex that associates with the RNA polymerase II subunit POLR2A (MIM 180660) and with a histone methyltransferase complex (Rozenblatt-Rosen et al., 2005 [PubMed 15632063]).[supplied by OMIM, Mar 2008]

LEO1 links:

MAPK6 (HGNC:6879): (mitogen-activated protein kinase 6) The protein encoded by this gene is a member of the Ser/Thr protein kinase family, and is most closely related to mitogen-activated protein kinases (MAP kinases). MAP kinases also known as extracellular signal-regulated kinases (ERKs), are activated through protein phosphorylation cascades and act as integration points for multiple biochemical signals. This kinase is localized in the nucleus, and has been reported to be activated in fibroblasts upon treatment with serum or phorbol esters. [provided by RefSeq, Jul 2008]

Ambry Genetics

May 24, 2023

The c.1274G>C (p.R425P) alteration is located in exon 7 (coding exon 7) of the LEO1 gene. This alteration results from a G to C substitution at nucleotide position 1274, causing the arginine (R) at amino acid position 425 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
