Genes affected
ACVRL1 (HGNC:175): (activin A receptor like type 1) This gene encodes a type I cell-surface receptor for the TGF-beta superfamily of ligands. It shares with other type I receptors a high degree of similarity in serine-threonine kinase subdomains, a glycine- and serine-rich region (called the GS domain) preceding the kinase domain, and a short C-terminal tail. The encoded protein, sometimes termed ALK1, shares similar domain structures with other closely related ALK or activin receptor-like kinase proteins that form a subfamily of receptor serine/threonine kinases. Mutations in this gene are associated with hemorrhagic telangiectasia type 2, also known as Rendu-Osler-Weber syndrome 2. [provided by RefSeq, Jul 2008]

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 6 ACMG points.
PM1
In a disulfide_bond (size 23) in uniprot entity ACVL1_HUMAN there are 9 pathogenic changes around while only 1 benign (90%) in NM_000020.3
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the ACVRL1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 203 curated pathogenic missense variants (we use a threshold of 10). The gene has 24 curated benign missense variants. Gene score misZ: 2.4458 (below the threshold of 3.09). Trascript score misZ: 3.182 (above the threshold of 3.09). GenCC associations: The gene is linked to hereditary hemorrhagic telangiectasia, telangiectasia, hereditary hemorrhagic, type 2.
PP5
Variant 12-51913180-GGGCC-AGCCT is Pathogenic according to our data. Variant chr12-51913180-GGGCC-AGCCT is described in ClinVar as [Pathogenic]. Clinvar id is 8247.Status of the report is no_assertion_criteria_provided, 0 stars.
