Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2PP2BP4_Strong
The NM_017617.5(NOTCH1):c.244G>T(p.Val82Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign 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. V82M) has been classified as Likely benign.

Adams-Oliver syndrome 5 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jul 30, 2018 | This sequence change replaces valine with leucine at codon 82 of the NOTCH1 protein (p.Val82Leu). The valine residue is weakly conserved and there is a small physicochemical difference between valine and leucine. 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. - |
