Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_017617.5(NOTCH1):c.5284C>T(p.Arg1762Trp) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,460,008 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1762Q) has been classified as Uncertain significance.

Adams-Oliver syndrome 5 Uncertain:2

This sequence change replaces arginine with tryptophan at codon 1762 of the NOTCH1 protein (p.Arg1762Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with NOTCH1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
