Uncertain significance, criteria provided, single submitter | clinical testing | ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories | Oct 19, 2023 | The NOTCH1 c.2734C>T; p.Arg912Trp variant (rs201620358) is reported in the literature in individuals with aortic valve stenosis, aortic root aneurysm, bicuspid aortic valve, or coarctation of the aorta (Kerstjens-Frederikse 2016, Ziganshin 2015). Incomplete penetrance and variable expressivity are reported for NOTCH1 (Roifman 2021). This variant is also reported in ClinVar (Variation ID: 134921). This variant is found in the general population with an overall allele frequency of 0.18% (469/263284 alleles, including one homozygote) in the Genome Aggregation Database. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.402). Based on the available information, the clinical significance of this variant is uncertain.

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Apr 21, 2017 | The R912W variant of uncertain significance in the NOTCH1 gene has previously been reported in a 52 year-old male with an aortic root aneurysm and bicuspid aortic valve (Ziganshin et al., 2015). This variant has also been reported in 5 unrelated Dutch individuals with left-sided congenital heart defects; one individual with a bicuspid aortic valve, one individual with aortic valve stenosis, and three individuals with coarctation of the aorta (Kerstjens-Frederikse et al., 2016). For one of the individuals with coarctation of the aorta, this variant was also found in the father who had a bicuspid aortic valve; segregation studies for the remaining four individuals were either not completed or non-informative (Kerstjens-Frederikse et al., 2016). R912W was observed in approximately 0.3% of alleles from individuals of European (Non-Finnish) ancestry and 0.2% of alleles from individuals of both Latino and European (Finnish) ancestry in the Exome Aggregation Consortium, indicating it may be a rare benign variant in these populations (Lek et al., 2016). Furthermore, this substitution occurs at a position that is not conserved across species. Nevertheless, R912W variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In silico analysis predicts this variant is probably damaging to the protein structure/function. - |

Familial thoracic aortic aneurysm and aortic dissection Benign:3
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 08, 2019 | This alteration is classified as likely 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. - |

Aortic valve disease 1;C4014970:Adams-Oliver syndrome 5 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Center for Genomics, Ann and Robert H. Lurie Children's Hospital of Chicago | Mar 30, 2021 | NOTCH1 NM_017617.5 exon 17 p.Arg912Trp (c.2734C>T): This variant has been reported in the literature in one individual with an aortic aneurysm and in five individuals with nonsyndromic congenital heart disease (bicuspid aortic valve, coarctation of the aorta, aortic valve stenosis) (Ziganshin 2015 PMID:26188975, Kerstijens-Frederikse 2016 PMID:26820064). However, this variant is also present in 0.2% (317/119414) of European alleles in the Genome Aggregation Database, including one homozygote (https://gnomad.broadinstitute.org/variant/9-139405111-G-A). This variant is present in ClinVar (Variation ID:134921). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. - |
