Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PRMT7 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Arginine methyltransferase that can both catalyze the formation of omega-N monomethylarginine (MMA) and symmetrical dimethylarginine (sDMA), with a preference for the formation of MMA. Specifically mediates the symmetrical dimethylation of arginine residues in the small nuclear ribonucleoproteins Sm D1 (SNRPD1) and Sm D3 (SNRPD3); such methylation being required for the assembly and biogenesis of snRNP core particles. Specifically mediates the symmetric dimethylation of histone H4 'Arg-3' to form H4R3me2s. Plays a role in gene imprinting by being recruited by CTCFL at the H19 imprinted control region (ICR) and methylating histone H4 to form H4R3me2s, possibly leading to recruit DNA methyltransferases at these sites. May also play a role in embryonic stem cell (ESC) pluripotency. Also able to mediate the arginine methylation of histone H2A and myelin basic protein (MBP) in vitro; the relevance of such results is however unclear in vivo. {ECO:0000269|PubMed:15044439, ECO:0000269|PubMed:15494416, ECO:0000269|PubMed:17709427, ECO:0000269|PubMed:19110445}.
• Disease: DISEASE: Short stature, brachydactyly, intellectual developmental disability, and seizures (SBIDDS) [MIM:617157]: An autosomal recessive disease characterized by developmental delay, learning disabilities, mild mental retardation, delayed speech, and skeletal abnormalities. Skeletal features include short stature, brachydactyly, and short metacarpals and metatarsals. {ECO:0000269|PubMed:26437029}. Note=The disease is caused by mutations affecting the gene represented in this entry.
