Hereditary cancer-predisposing syndrome Uncertain:2
This missense variant replaces alanine with threonine at codon 13 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 hereditary cancer in the literature. This variant has been identified in 1/251334 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. -
The p.A13T variant (also known as c.37G>A), located in coding exon 1 of the BMPR1A gene, results from a G to A substitution at nucleotide position 37. The alanine at codon 13 is replaced by threonine, an amino acid with similar properties. This amino acid position is well 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. -
Juvenile polyposis syndrome Uncertain:1
This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 13 of the BMPR1A protein (p.Ala13Thr). This variant is not present in population databases (gnomAD no frequency). 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: 239861). 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%. 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. -
