Genes affected

NOTCH1 (HGNC:7881): (notch receptor 1) This gene encodes a member of the NOTCH family of proteins. Members of this Type I 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 signaling is an evolutionarily conserved intercellular signaling pathway that regulates interactions between physically adjacent cells through binding of Notch family receptors to their cognate ligands. The encoded preproprotein is proteolytically processed in the trans-Golgi network to generate two polypeptide chains that heterodimerize to form the mature cell-surface receptor. This receptor plays a role in the development of numerous cell and tissue types. Mutations in this gene are associated with aortic valve disease, Adams-Oliver syndrome, T-cell acute lymphoblastic leukemia, chronic lymphocytic leukemia, and head and neck squamous cell carcinoma.

NOTCH1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NOTCH1. . Trascript score misZ 3.6761 (greater than threshold 3.09). GenCC has associacion of gene with familial bicuspid aortic valve, familial thoracic aortic aneurysm and aortic dissection, Adams-Oliver syndrome, connective tissue disorder, Adams-Oliver syndrome 5, aortic valve disease 1.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.847
