Variant summary

Our verdict is Pathogenic. Variant got 14 ACMG points: 14P and 0B. PS1_ModeratePM1PM2PM5PP3_StrongPP5_Moderate

The NM_000435.3(NOTCH3):​c.634T>A​(p.Cys212Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,908 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 Pathogenic (★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C212R) 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 14 ACMG points.

PS1
Transcript NM_000435.3 (NOTCH3) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 2 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 chr19-15192005-A-C is described in ClinVar as [Pathogenic]. Clinvar id is 2915520.Status of the report is criteria_provided_single_submitter, 1 stars.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.996
PP5
Variant 19-15192005-A-T is Pathogenic according to our data. Variant chr19-15192005-A-T is described in ClinVar as [Pathogenic]. Clinvar id is 447864.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr19-15192005-A-T is described in Lovd as [Pathogenic].
