Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2PP2PP3_Moderate
The NM_017617.5(NOTCH1):c.3974C>A(p.Ala1325Asp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. A1325A) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Genome-Nilou Lab | Mar 15, 2022 | - - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 21, 2017 | This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a NOTCH1-related disease. This sequence change replaces alanine with aspartic acid at codon 1325 of the NOTCH1 protein (p.Ala1325Asp). The alanine residue is highly conserved and there is a moderate physicochemical difference between alanine and aspartic acid. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. - |
