Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM1PP2PP3
The NM_004329.3(BMPR1A):c.1412G>A(p.Arg471His) variant causes a missense change. The variant allele was found at a frequency of 0.00000684 in 1,461,886 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R471C) has been classified as Uncertain significance.

Juvenile polyposis syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | All of Us Research Program, National Institutes of Health | Feb 05, 2024 | This missense variant replaces arginine with histidine at codon 471 of the BMPR1A protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 3/251488 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 20, 2024 | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 471 of the BMPR1A protein (p.Arg471His). This variant is present in population databases (rs779371501, gnomAD 0.003%). 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: 489687). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is not expected to disrupt BMPR1A function with a negative predictive value of 95%. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on BMPR1A function (PMID: 29522511). 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. - |

Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Jul 20, 2023 | This missense variant replaces arginine with histidine at codon 471 of the BMPR1A protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). Functional studies performed are not sufficient to determine the impact of this variant on BMPR1A protein function (PMID: 29522511). This variant has not been reported in individuals affected with BMPR1A-related disorders in the literature. This variant has been identified in 3/251488 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. - |
Benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 07, 2023 | 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. - |
