Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ACVRL1 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: Type I receptor for TGF-beta family ligands BMP9/GDF2 and BMP10 and important regulator of normal blood vessel development. On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. May bind activin as well. {ECO:0000269|PubMed:22718755, ECO:0000269|PubMed:22799562, ECO:0000269|PubMed:26176610}.;
Disease
DISEASE: Telangiectasia, hereditary hemorrhagic, 2 (HHT2) [MIM:600376]: A multisystemic vascular dysplasia leading to dilation of permanent blood vessels and arteriovenous malformations of skin, mucosa, and viscera. The disease is characterized by recurrent epistaxis and gastro-intestinal hemorrhage. Visceral involvement includes arteriovenous malformations of the lung, liver, and brain. {ECO:0000269|PubMed:10694922, ECO:0000269|PubMed:10767348, ECO:0000269|PubMed:11170071, ECO:0000269|PubMed:11484689, ECO:0000269|PubMed:14684682, ECO:0000269|PubMed:15024723, ECO:0000269|PubMed:15712270, ECO:0000269|PubMed:16525724, ECO:0000269|PubMed:16752392, ECO:0000269|PubMed:20414677, ECO:0000269|PubMed:26176610, ECO:0000269|PubMed:8640225, ECO:0000269|PubMed:9245985}.
