Genes affected
PRMT9 (HGNC:25099): (protein arginine methyltransferase 9) This gene encodes a type II methyltransferase. Post-translational modification of target proteins by PRMTs plays an important regulatory role in many biological processes, whereby PRMTs methylate arginine residues by transferring methyl groups from S-adenosyl-L-methionine to the guanidino nitrogen atoms of arginine. The protein encoded by this gene methylates spliceosome associated protein 145 to regulate alternative splicing and acts as a modulator of small nuclear ribonucleoprotein maturation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Apr 2017]
TMEM184C (HGNC:25587): (transmembrane protein 184C) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
