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.

The NOTCH1 c.5414T>C; p.Leu1805Pro variant (rs201779159) is reported in the literature in an individual affected with bicuspid aortic valve disease (Girdauskas 2017). This variant is reported in ClinVar (Variation ID: 499922) and if found in the non-Finnish European population with an allele frequency of 0.0109% (14/128,060 alleles) in the Genome Aggregation Database. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.648). Due to limited information, the clinical significance of this variant is uncertain at this time. References: Girdauskas E et al. Genetic abnormalities in bicuspid aortic valve root phenotype: preliminary results. Eur J Cardiothorac Surg. 2017 Jul 1;52(1):156-162. PMID: 28387797. -

The NOTCH1 c.5414T>C variant is predicted to result in the amino acid substitution p.Leu1805Pro. This variant was reported in a study of individuals with bicuspid aortic valve-associated aortopathy, however additional details were not provided (Girdauskas et al. 2017. PubMed ID: 28387797; Girdauskas et al. 2018. PubMed ID: 30059548). This variant is reported in 0.011% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-139396511-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

The p.L1805P variant (also known as c.5414T>C), located in coding exon 29 of the NOTCH1 gene, results from a T to C substitution at nucleotide position 5414. The leucine at codon 1805 is replaced by proline, an amino acid with similar properties. This alteration was reported in a bicuspid aortic valve cohort (Girdauskas E et al. Eur J Cardiothorac Surg, 2017 Jul;52:156-162). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
