Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP2PP3_Strong

The NM_017617.5(NOTCH1):​c.1367G>T​(p.Cys456Phe) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C456Y) has been classified as Likely pathogenic.

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.

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 11 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 4 benign, 5 uncertain in NM_017617.5
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr9-136517826-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 219377.Status of the report is criteria_provided_single_submitter, 1 stars.
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, 0.997
