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.

Submissions by phenotype
Hereditary cancer-predisposing syndrome Benign:2
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 03, 2021 | 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. - |

Juvenile polyposis syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 10, 2022 | 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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 411613). This variant has not been reported in the literature in individuals affected with BMPR1A-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change falls in intron 4 of the BMPR1A gene. It does not directly change the encoded amino acid sequence of the BMPR1A protein. It affects a nucleotide within the consensus splice site. - |
