Submissions by phenotype
NOTCH1-related disorder Uncertain:1
The NOTCH1 c.2501C>T variant is predicted to result in the amino acid substitution p.Ala834Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0066% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Familial thoracic aortic aneurysm and aortic dissection Uncertain:1
The p.A834V variant (also known as c.2501C>T), located in coding exon 16 of the NOTCH1 gene, results from a C to T substitution at nucleotide position 2501. The alanine at codon 834 is replaced by valine, an amino acid with similar properties. 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 alteration remains unclear. -
