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.

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The BMPR1A c.961C>T; p.Leu321Leu variant (rs377412651), to our knowledge, is not reported in the medical literature but is reported as benign or likely benign in ClinVar (Variation ID: 184634). This variant is observed in the general population with an overall allele frequency of 0.02% (55/276926 alleles) in the Genome Aggregation Database. This is a synonymous change and computational algorithms do not predict this variant to impact splicing (Alamut v.2.10). Based on available information, this variant is considered likely benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: The BMPR1A c.961C>T (p.Leu321Leu) variant involves the alteration of a conserved nucleotide causing a synonymous change and 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may create an ESE binding site. However, these predictions have yet to be confirmed by functional studies. This variant was found in 55/276926 control chromosomes at a frequency of 0.0001986, which is approximately 99 times the estimated maximal expected allele frequency of a pathogenic BMPR1A variant (0.000002), suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign/benign. Taken together, this variant is classified as benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
