Genes affected

BMPR1A (HGNC:1076): (bone morphogenetic protein receptor type 1A) The bone morphogenetic protein (BMP) receptors are a family of transmembrane serine/threonine kinases that include the type I receptors BMPR1A and BMPR1B and the type II receptor BMPR2. These receptors are also closely related to the activin receptors, ACVR1 and ACVR2. The ligands of these receptors are members of the TGF-beta superfamily. TGF-betas and activins transduce their signals through the formation of heteromeric complexes with 2 different types of serine (threonine) kinase receptors: type I receptors of about 50-55 kD and type II receptors of about 70-80 kD. Type II receptors bind ligands in the absence of type I receptors, but they require their respective type I receptors for signaling, whereas type I receptors require their respective type II receptors for ligand binding.

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM1: In a topological_domain Extracellular (size 128) in uniprot entity BMR1A_HUMAN there are 7 pathogenic changes around while only 0 benign (100%) in NM_004329.3
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the BMPR1A gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 17 curated pathogenic missense variants (we use a threshold of 10). The gene has 19 curated benign missense variants. Gene score misZ: 1.9176 (below the threshold of 3.09). Trascript score misZ: 3.8989 (above the threshold of 3.09). GenCC associations: The gene is linked to polyposis syndrome, hereditary mixed, 2, generalized juvenile polyposis/juvenile polyposis coli, hereditary mixed polyposis syndrome, pulmonary arterial hypertension, juvenile polyposis syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.888
