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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2022The c.2107G>C (p.V703L) alteration is located in exon 10 (coding exon 10) of the PRMT9 gene. This alteration results from a G to C substitution at nucleotide position 2107, causing the valine (V) at amino acid position 703 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
