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.

Juvenile polyposis syndrome

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	May 25, 2020	This sequence change replaces glycine with valine at codon 47 of the BMPR1A protein (p.Gly47Val). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and valine. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). This variant has not been reported in the literature in individuals with BMPR1A-related conditions. ClinVar contains an entry for this variant (Variation ID: 419865). This variant is present in population databases (rs368595543, ExAC 0.001%). -
Uncertain significance, criteria provided, single submitter	clinical testing	All of Us Research Program, National Institutes of Health	Dec 18, 2023	This missense variant replaces glycine with valine at codon 47 of the BMPR1A protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with BMPR1A-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

This variant is denoted BMPR1A c.140G>T at the cDNA level, p.Gly47Val (G47V) at the protein level, and results in the change of a Glycine to a Valine (GGA>GTA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BMPR1A Gly47Val was not observed at a significant allele frequency in the NHLBI Exome Sequencing Project. Since Glycine and Valine share similar properties, this is considered a conservative amino acid substitution. BMPR1A Gly47Val occurs at a position that is conserved in mammals and is located within the extracellular domain (UniProt). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available information, it is unclear whether BMPR1A Gly47Val is pathogenic or benign. We consider it to be a variant of uncertain significance. -
