| Invitae | RCV001228641 | SCV001401049 | uncertain significance | Juvenile polyposis syndrome | 2023-03-20 | criteria provided, single submitter | clinical testing | 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BMPR1A protein function. ClinVar contains an entry for this variant (Variation ID: 955921). This variant has not been reported in the literature in individuals affected with BMPR1A-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 137 of the BMPR1A protein (p.Thr137Pro). |
| Ambry Genetics | RCV002322103 | SCV002630576 | uncertain significance | Hereditary cancer-predisposing syndrome | 2018-06-27 | criteria provided, single submitter | clinical testing | The p.T137P variant (also known as c.409A>C), located in coding exon 4 of the BMPR1A gene, results from an A to C substitution at nucleotide position 409. The threonine at codon 137 is replaced by proline, an amino acid with highly similar properties. 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. |
