Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS2
The NM_004329.3(BMPR1A):c.140G>A(p.Gly47Glu) variant causes a missense change. The variant allele was found at a frequency of 0.00000682 in 1,613,952 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G47V) has been classified as Uncertain significance.

Juvenile polyposis syndrome Uncertain:4
This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 47 of the BMPR1A protein (p.Gly47Glu). This variant is present in population databases (rs368595543, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with BMPR1A-related conditions. ClinVar contains an entry for this variant (Variation ID: 186884). Invitae Evidence Modeling incorporating data from in vitro experimental studies (internal data) indicates that this missense variant is not expected to disrupt BMPR1A function with a negative predictive value of 95%. 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. -
This variant is classified as a variant of uncertain significance as there is insufficient evidence to determine its impact on protein function and/or cancer risk. -

This missense variant replaces glycine with glutamic acid 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 been identified in 9/251408 chromosomes 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. -
not provided Uncertain:2
In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
The BMPR1A c.140G>A (p.Gly47Glu) variant has not been reported in individuals with BMPR1A-related conditions in the published literature. The frequency of this variant in the general population, 0.00026 (9/34590 chromosomes in Admixed American subpopulation (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is higher than would generally be expected for pathogenic variants in this gene. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is deleterious or benign. Based on the available information, we are unable to determine the clinical significance of this variant. -
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
This alteration is classified as 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. -
