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).

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.48).

BP6

Variant 19-15166054-C-A is Benign according to our data. Variant chr19-15166054-C-A is described in ClinVar as Benign. ClinVar VariationId is 256143.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-1.24 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00544 (828/152272) while in subpopulation AFR AF = 0.0192 (797/41546). AF 95% confidence interval is 0.0181. There are 8 homozygotes in GnomAd4. There are 396 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 8 AD,AR gene
