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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), BMPR1A. . Gene score misZ 1.9176 (greater than the threshold 3.09). Trascript score misZ 3.8989 (greater than threshold 3.09). GenCC has associacion of gene with polyposis syndrome, hereditary mixed, 2, generalized juvenile polyposis/juvenile polyposis coli, hereditary mixed polyposis syndrome, pulmonary arterial hypertension, juvenile polyposis syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.25785658).

Submissions by phenotype

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2023The p.R188S variant (also known as c.562C>A), located in coding exon 6 of the BMPR1A gene, results from a C to A substitution at nucleotide position 562. The arginine at codon 188 is replaced by serine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
