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.

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	May 17, 2023	The p.Q353R variant (also known as c.1058A>G), located in coding exon 8 of the BMPR1A gene, results from an A to G substitution at nucleotide position 1058. The glutamine at codon 353 is replaced by arginine, an amino acid with highly similar properties. This alteration has been previously identified in one individual from a North American cohort of individuals with early onset colon cancer. (Pearlman R et al. JAMA Oncol, 2017 Apr;3:464-471).This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Juvenile polyposis syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Oct 04, 2021	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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 460472). This missense change has been observed in individual(s) with colon cancer (PMID: 27978560). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with arginine at codon 353 of the BMPR1A protein (p.Gln353Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine. -
