Adams-Oliver syndrome 5 Uncertain:2
This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 90 of the NOTCH1 protein (p.Ala90Val). Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This variant has not been reported in the literature in individuals affected with NOTCH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 520084). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
- -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Aortic valve disease 1 Uncertain:1
- -
Familial thoracic aortic aneurysm and aortic dissection Benign:1
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. -
