Submissions by phenotype
not provided Uncertain:2
- -
Not observed in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Adams-Oliver syndrome 5 Uncertain:2
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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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 NOTCH1 protein function. ClinVar contains an entry for this variant (Variation ID: 264032). This variant has not been reported in the literature in individuals affected with NOTCH1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 593 of the NOTCH1 protein (p.Pro593Leu). -

Familial thoracic aortic aneurysm and aortic dissection Uncertain:1
The p.P593L variant (also known as c.1778C>T), located in coding exon 11 of the NOTCH1 gene, results from a C to T substitution at nucleotide position 1778. The proline at codon 593 is replaced by leucine, an amino acid with similar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6463 samples (12926 alleles) with coverage at this position. This amino acid position is 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 variant remains unclear. -
