Genes affected

NOTCH2 (HGNC:7882): (notch receptor 2) This gene encodes a member of the Notch family. Members of this Type 1 transmembrane protein family share structural characteristics including an extracellular domain consisting of multiple epidermal growth factor-like (EGF) repeats, and an intracellular domain consisting of multiple, different domain types. Notch family members play a role in a variety of developmental processes by controlling cell fate decisions. The Notch signaling network is an evolutionarily conserved intercellular signaling pathway which regulates interactions between physically adjacent cells. In Drosophilia, notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signaling pathway that plays a key role in development. Homologues of the notch-ligands have also been identified in human, but precise interactions between these ligands and the human notch homologues remain to be determined. This protein is cleaved in the trans-Golgi network, and presented on the cell surface as a heterodimer. This protein functions as a receptor for membrane bound ligands, and may play a role in vascular, renal and hepatic development. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2011]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NOTCH2. . Gene score misZ 3.5024 (greater than the threshold 3.09). Trascript score misZ 6.0283 (greater than threshold 3.09). GenCC has associacion of gene with Alagille syndrome due to a NOTCH2 point mutation, Alagille syndrome, Acroosteolysis dominant type.

BP4

Computational evidence support a benign effect (MetaRNN=0.012528539).

BP6

Variant 1-119967571-C-T is Benign according to our data. Variant chr1-119967571-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 463169.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-119967571-C-T is described in Lovd as [Likely_benign].

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000243 (37/152308) while in subpopulation SAS AF= 0.00518 (25/4822). AF 95% confidence interval is 0.0036.
