Ambry Genetics RCV001015310 SCV001176130 uncertain significance Hereditary cancer-predisposing syndrome 2023-06-14 criteria provided, single submitter clinical testing The p.N79S variant (also known as c.236A>G), located in coding exon 3 of the BMPR1A gene, results from an A to G substitution at nucleotide position 236. The asparagine at codon 79 is replaced by serine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Invitae RCV001365326 SCV001561592 uncertain significance Juvenile polyposis syndrome 2022-04-17 criteria provided, single submitter clinical testing 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: 821164). 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 asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 79 of the BMPR1A protein (p.Asn79Ser). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
