Variant summary

Our verdict is Benign. The variant received -18 ACMG points: 2P and 20B. PM5BP4_StrongBP6_Very_StrongBS1BS2

The NM_000435.3(NOTCH3):c.2039G>A(p.Arg680His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00262 in 1,613,488 control chromosomes in the GnomAD database, including 99 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R680C) has been classified as Likely 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).

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -18 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr19-15185593-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1676246.

BP4

Computational evidence support a benign effect (MetaRNN=0.0072473586).

BP6

Variant 19-15185592-C-T is Benign according to our data. Variant chr19-15185592-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 256125.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0141 (2144/152178) while in subpopulation AFR AF = 0.0489 (2028/41492). AF 95% confidence interval is 0.0471. There are 55 homozygotes in GnomAd4. There are 1032 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2
