Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 1P and 13B. PP3BP4_StrongBP6BS1BS2

The NM_017617.5(NOTCH1):c.2495C>T(p.Pro832Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00017 in 1,612,396 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P832S) has been classified as Uncertain significance.

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 was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, Cadd, Dann, M_CAP, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when BayesDel_addAF, max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.053106725).

BP6

Variant 9-136511244-G-A is Benign according to our data. Variant chr9-136511244-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 134918.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000368 (56/152256) while in subpopulation AMR AF = 0.00307 (47/15298). AF 95% confidence interval is 0.00237. There are 1 homozygotes in GnomAd4. There are 38 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 56 AD gene.
