Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1PM2PM5PP3_StrongPP5_Moderate
The NM_000435.3(NOTCH3):c.349T>G(p.Cys117Gly) variant causes a missense change. 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 Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C117F) has been classified as Pathogenic.

Genes affected
NOTCH3 (HGNC:7883): (notch receptor 3) This gene encodes the third discovered human homologue of the Drosophilia melanogaster type I membrane protein notch. In Drosophilia, notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signalling pathway that plays a key role in neural development. Homologues of the notch-ligands have also been identified in human, but precise interactions between these ligands and the human notch homologues remains to be determined. Mutations in NOTCH3 have been identified as the underlying cause of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).

Classification made for transcript
Verdict is Pathogenic. Variant got 12 ACMG points.
PM1
?
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 3 benign, 3 uncertain in NM_000435.3
PM2
?
Very rare variant in population databases, with high coverage;
PM5
?
Other missense variant is known to change same aminoacid residue: Variant chr19-15192289-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 447838.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
PP3
?
MetaRNN computational evidence supports a deleterious effect, 0.992
PP5
?
Variant 19-15192290-A-C is Pathogenic according to our data. Variant chr19-15192290-A-C is described in ClinVar as [Pathogenic]. Clinvar id is 447836.Status of the report is criteria_provided_single_submitter, 1 stars.
