Color Diagnostics, LLC DBA Color Health RCV001177667 SCV001341916 uncertain significance Hereditary cancer-predisposing syndrome 2019-11-25 criteria provided, single submitter clinical testing This missense variant replaces glutamic acid with glycine at codon 452 of the BMPR1A protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 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 been reported in an individual undergoing testing for Lynch Syndrome (PMID 25980754). This variant has not been identified 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.
Ambry Genetics RCV001177667 SCV002689285 uncertain significance Hereditary cancer-predisposing syndrome 2021-12-29 criteria provided, single submitter clinical testing The p.E452G variant (also known as c.1355A>G), located in coding exon 10 of the BMPR1A gene, results from an A to G substitution at nucleotide position 1355. The glutamic acid at codon 452 is replaced by glycine, an amino acid with similar properties. This alteration was identified in a cohort of 1260 individuals undergoing panel testing for Lynch syndrome due to having a diagnosis of a Lynch-associated cancer and/or polyps (Yurgelun MB et al. Gastroenterology, 2015 Sep;149:604-13.e20). This amino acid position is not well 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.
